Updated SIP 484 handling; added Incomplete control frame

Browse Source 
When a SIP phone uses the dial application and receives a 484 Address 
Incomplete response, if overlapped dialing is enabled for SIP, then
the 484 Address Incomplete is forwarded back to the SIP phone and the
HANGUPCAUSE channel variable is set to 28.  Previously, the Incomplete
application dialplan logic was automatically triggered; now, explicit
dialplan usage of the application is required.

Additionally, this patch adds a new AST_CONTOL_FRAME type called
AST_CONTROL_INCOMPLETE.  If a channel driver receives this control frame,
it is an indication that the dialplan expects more digits back from the
device.  If the device supports overlap dialing it should attempt to 
notify the device that the dialplan is waiting for more digits; otherwise,
it can handle the frame in a manner appropriate to the channel driver.
