439f7bb848 res_pjsip, res_pjsip_session: initialize local variables
This patch initializes a couple of local variables to some default values.
Interestingly, in the 'pj_status_t dlg_status' case the value not being
initialized caused memory to grow, and not be recovered, in the off nominal
path (at least on my machine).

20f672539e pjsip_transport_management: Shutdown transport immediately on disconnect
The transport management code that checks for idle connections keeps a
reference to PJSIP's transport for IDLE_TIMEOUT milliseconds (32000 by
default). Because of this, if the transport is closed before this
timeout, the idle checking code will keep the transport from actually
being shutdown until the timeout expires.

Rather than passing the AO2 object to the scheduler task, we just pass
its key and look it up when it is time to potentially close the idle
connection. The other transport management code handles cleaning up
everything else for us.

Additionally, because we use the address of the transport when
generating its name, we concatenate an incrementing ID to the end of the
name to guarantee uniqueness.

0aff1a278e res_pjsip/pjsip_transport_management.c: Fix deadlock with transport keep alive.
Using the keep_alive_interval option can result in a deadlock between the
pjproject transport manager group lock and the monitored transports ao2
container lock.  The pjproject transport manager group lock has to be
superior in the locking order to the monitored transports ao2 container
lock because of pjproject callbacks called when already holding the group
lock.  The lock inversion happens when Asterisk attempts to send a keep
alive packet over the reliable transports.

* Made keepalive_transport_thread() iterate over the monitored transports
container rather than use the ao2_callback() method.  This avoids holding
the container lock when sending the keep alive packet.

758409de56 AST-2018-005: res_pjsip_transport_management: Move to core
Since res_pjsip_transport_management provides several attack
mitigation features, its functionality moved to res_pjsip and
this module has been removed.  This way the features will always
be available if res_pjsip is loaded.
