  Fix a situation in which Asterisk would not stop retransmitting 487s.
  
  If a CANCEL were received by Asterisk, we would send a 487 in response
  to the original INVITE and a 200 OK for the CANCEL. If there were a network
  hiccup which caused the 200 OK and the 487 to be lost, then the UA communicating
  with Asterisk may try to retransmit its CANCEL. Asterisk's response to this used
  to be to try sending another 487 to the canceled INVITE and another 200 OK to the
  CANCEL.
  
  The problem here is that the originally-sent 487 was sent "reliably" meaning that
  it will be retransmitted until it is received properly. So when we receive the second
  CANCEL it is likely that the first batch of 487s we sent is still going strong and
  reaches the UA. The result was that the second set of 487s would be retransmitted
  constantly until the maximum number of retries had been reached.
  
  The fix for this is that if we receive a second CANCEL for an INVITE, then we cancel
  the retransmission of the first set of 487s and start a second set. This causes the
  dialog to be terminated reasonably.

  Fix a possible infinite loop in SDP parsing during glare situation.
  
  There was a while loop in get_ip_and_port_from_sdp which was controlled
  by a call to get_sdp_iterate. The loop would exit either if what we were
  searching for was found or if the return was NULL. The problem is that
  get_sdp_iterate never returns NULL. This means that if what we were searching
  for was not present, the loop would run infinitely. This modification of the
  loop fixes the problem.

99b98d8f9a Fix problem with no audio due to ignoring the SDP.
A recent change to our SDP version comparison made audio not function
on some calls. This was because of a test wherein we were trying to
see if an unsigned value was less than 0. This is a dumb comparison
and arguably the compiler should have warned about it. Alas, though,
it slipped past. Now it's fixed by changing the variable to be a
signed type.

Found by several developers. Tested by mnicholson and dbrooks.

9bf67151c9 SIP registry ref count error
During a sip reload, the list of sip_registry objects are
supposed to be traversed, unlinked, and destroyed, but
destruction never takes place due to a ref counting error.
This causes a memory leak when registry items are removed
from sip.conf and reloaded.  While the registries are removed
from the global list, they are not removed from the scheduler.
Because of this, SIP register attempts continue to be sent
out for the item even though it may no longer be in the .conf.

f1dc620467 Enable applications to enable/disable digit and tone detection.
Some applications (notably app_fax) do not need digit detection nor FAX tone
detection while they are running, and if Asterisk is using software DSPs to provide
the detection, this consumes extra CPU cycles that could be better spent on the
actual application. This patch allows applications to query and control the state
of digit and tone detection on a channel, and modifies app_fax to disable them
while the FAX operations are occurring (and re-enable digit detection afterwards).

ee8cdd555f SIP transport type issues
What this patch addresses:
1. ast_sip_ouraddrfor() by default binds to the UDP address/port
reguardless if the sip->pvt is of type UDP or not.  Now when no
remapping is required, ast_sip_ouraddrfor() checks the sip_pvt's
transport type, attempting to set the address and port to the
correct TCP/TLS bindings if necessary.
2.  It is not necessary to send the port number in the Contact
header unless the port is non-standard for the transport type.
This patch fixes this and removes the todo note.
3.  In sip_alloc(), the default dialog built always uses transport
type UDP.  Now sip_alloc() looks at the sip_request (if present)
and determines what transport type to use by default.
4.  When changing the transport type of a sip_socket, the file
descriptor must be set to -1 and in some cases the tcptls_session's
ref count must be decremented and set to NULL.  I've encountered
several issues associated with this process and have created a function,
set_socket_transport(), to handle the setting of the socket type.

85e57521ab Accept T.38 re-INVITE responses with invalid SDP versions.
This commit changes the 'incoming SDP version' check logic a bit more; when
'ignoresdpversion' is *not* set for a peer, if we initiate a re-INVITE to
switch to T.38, we'll always accept the peer's SDP response, even if they
don't properly increment the SDP version number as they should. If this situation
occurs, a warning message will be generated suggesting that the peer's
configuration be changed to include the 'ignoresdpversion' configuration option
(although ideally they'd fix their SIP implementation to be RFC compliant).

78ee46f13f Some minor structure size improvements in sip_pvt and sip_peer.
Using the 'pahole' tool, it is now quite easy to see where structure fields
could be organized differently to keep the compiler from having to add
padding to satisfy alignment requirements. These changes reduced the sizes of
sip_pvt and sip_peer by a few bytes each (on 64-bit platforms), and also fixed
a spelling error in a field name.

14d05f57d7 A few fixes to SIP with regards to connected line updates during transfers.
* Set the invitestate to INV_CALLING when we send a connected line reinvite.
This prevents us from potentially rapid-firing reinvites to a single peer.

* Use the astdb to store a peer's allowed methods. This prevents us from sending
an UPDATE during the interval between startup and the peer's first registration
if the peer does not support the UPDATE method.

* Handle Polycom's method of indicating allowed methods in REGISTER. Instead of
using an Allow header, they place the allowed methods in a methods= parameter
in the Contact header.

f50bb3bfa4 SIP set outbound transport type from Registration
In sip.conf the transport option allows for the configuration of what transport types (udp, tcp, and tls) a peer will accept, but only the first type listed was used for outbound connections.  This patch changes this.  Now the default transport type is only used until the peer registers.  When registration takes place the transport type is parsed out of the Contact header.  If the Contact header's transport type is equal to one that the peer supports, the peer's default transport type for outbound connections is set to match the Contact header's type.  If the Contact header's transport type is not present, then the peer's default transport type is set to match the one the peer registered with.  When a peer unregisters or the registration expires, the default transport type for that peer is reset.

2c882626a0 Implement a new element in AstXML for AMI actions documentation.
A new xml element was created to manage the AMI actions documentation,
using AstXML.
To register a manager action using XML documentation it is now possible
using ast_manager_register_xml().
The CLI command 'manager show command' can be used to show the parsed
documentation.

Example manager xml documentation:
<manager name="ami action name" language="en_US">
    <synopsis>
        AMI action synopsis.
    </synopsis>
    <syntax>
        <xi:include xpointer="xpointer(...)" /> <-- for ActionID
        <parameter name="header1" required="true">
	    <para>Description</para>
	</parameter>
	...
    </syntax>
    <description>
        <para>AMI action description</para>
    </description>
    <see-also>
    	...
    </see-also>
</manager>

e6b2e9a750 Const-ify the world (or at least a good part of it)
This patch adds 'const' tags to a number of Asterisk APIs where they are appropriate (where the API already demanded that the function argument not be modified, but the compiler was not informed of that fact). The list includes:

- CLI command handlers
- CLI command handler arguments
- AGI command handlers
- AGI command handler arguments
- Dialplan application handler arguments
- Speech engine API function arguments

In addition, various file-scope and function-scope constant arrays got 'const' and/or 'static' qualifiers where they were missing.

56903a7485 Get rid of some duplicated code and correct a connected line error.
When receiving a 200 OK response to an INVITE, it was possible to transmit two
connected line updates instead of a single one. Furthermore, the second did not
have the proper information present.

Now the two have been combined into a single update and the correct information
is presented.

7b4eeed257 Add basic support for handling connected line-related UPDATE requests.
SIP purists may want to look the other way...

When COLP/CONP support for SIP was committed, there was a condition under 
which Asterisk may transmit a SIP UPDATE in order to communicate the change 
in connected line information. The issue here is that while we could send a 
SIP UPDATE message, we were not prepared to receive such an UPDATE and would 
always responde with a 501 when we received an UPDATE.

The situation was a bit rough. We really want to be able to receive UPDATEs 
having to do with connected line changes, but the amount of effort involved 
in properly supporting RFC 3311 was staggering. This commit represents a 
compromise.

First, it was decided that it is important to only send a SIP UPDATE to 
an endpoint that is able to handle one. So, now we have added parsing of 
the Allow header into SIP. We store the allowed methods on SIP peers so 
that when we communicate with them, we already will know what we can and 
cannot send to them. We will parse the peer's allowed methods when he registers
with us. If the peer is not the type to register with us, but the qualify option 
is enabled, then we will use the response to the OPTIONS request we send 
the peer to determine the peer's allowed methods. When the peer's registration 
expires, or when qualify deems the peer to be unreachable, we clear the allowed 
methods from the peer.

For an actual call, we will copy the peer's allowed methods to the sip_pvt 
representing the call leg. If we are communicating with an endpoint which is 
not a peer, then we will just parse the Allow header from the first message 
we receive during the call and store the information in the sip_pvt.

If, during communication with a peer, we receive a 501 response, then we will 
make sure to save the fact that we cannot use that method when communicating 
with that peer.

Now, with all that infrastructure in place, the only actual place we use this 
information currently is when attempting to send a connected line change using 
an UPDATE request. If we cannot send the change immediately using an UPDATE, 
we will set the SIP_NEEDREINVITE flag so that we can send a REINVITE as soon 
as it is allowed.

The second part of the changes here is for Asterisk to accept UPDATE requests 
that have connected line changes. Since we are not fully supporting RFC 3311, 
Asterisk will NOT place the UPDATE method in Allow headers it sends. Instead, 
if you are communicating with what you know to be another Asterisk box, you may 
set the rpid_update parameter in sip.conf so that we will send UPDATEs to that 
Asterisk box. When we send a connected line update, we set a custom header 
called "X-Asterisk-rpid-update."

On the receiving end, if Asterisk receives an UPDATE that does not have the 
"X-Asterisk-rpid-update" header present, then Asterisk will respond with a 501 
since media-changing UPDATEs are not supported. We should never get such 
UPDATEs, since as was stated earlier, Asterisk does not put UPDATE in its Allow
header. If the custom header is present in the received UPDATE, though, then we 
will check the incoming request for connected line updates and queue the update
on the channel where the change occurred.

  Fix a race condition where a reinvite could trigger a 482 response.
  
  The loop detection/spiral detection code in chan_sip used the owner
  channel's state as a criterion for determining if the incoming INVITE
  is a looped request. The problem with this is that the INVITE-handling
  code happens in a different thread than the thread that marks the owner
  channel as being up. As a result, if a reinvite were to come in very quickly,
  say from another Asterisk on the same LAN, it was possible for the reinvite
  to arrive before the owner channel had been set to the up state.
  
  This patch corrects the problem by using the invitestate of the sip_pvt
  instead, since that can be guaranteed to be set correctly by the time
  the reinvite arrives. Since there is a switch statement further in the
  INVITE-handling code, the AST_STATE_RINGING state also checks the invitestate
  of the sip_pvt in case we should actually be treating the channel as if it were
  up already.

56275abb32 Update spiral support in trunk and 1.6.X to match what is in 1.4.
In 1.4, a SIP spiral is treated the same way as a call forward. This
works much better than what is currently in trunk and 1.6.X. The code
in trunk and 1.6.X did not create a new call to the recipient of the spiral,
instead trying to continue the same call. In addition to just being plain
wrong, this also had the side effect of only being able to spiral calls
to other SIP channels.

With this in place, as long as call forwards are honored, SIP spirals
will work properly. This means that it will work for outbound calls
made  by the Queue, Dial, and Page applications. For originated calls and
spool calls, however, the spiral will not work properly until a generic
call forward mechanism is introduced into Asterisk.

fbad7a508d TCP not matching valid peer.
find_peer() does not find a valid peer when using pvt->recv as the sockaddr_in argument.  Because of the way TCP works, the port number in pvt->recv is not what we're looking for at all.  There is currently only one place that find_peer searches for a peer using the sockaddr_in argument.  If the peer is not found after using pvt->recv (works for UDP since the port number will be correct), a temp sockaddr_in struct is made using the Contact header in the sip_request.  This has the correct port number in it.
