pjsip: Add patch to allow all transports to be destroyed.
If a transport is created with the same transport type, source
IP address, and source port as one that already exists the old
transport is moved into a linked list called "tp_list".
If this old transport is later shutdown it will not be destroyed
as the process checks whether the transport is valid or not. This
check does not look at the "tp_list" when making the determination
causing the transport to not be destroyed.
This change updates the logic to query not just the main storage
method for transports but also the "tp_list".

AST-2017-011 - res_pjsip_session: session leak when a call is rejected
A previous commit made it so when an invite session transitioned into a
disconnected state destruction of the Asterisk pjsip session object was
postponed until either a transport error occurred or the event timer
expired. However, if a call was rejected (for instance a 488) before the
session was fully established the event timer may not have been initiated,
or it was canceled without triggering either of the session finalizing states
mentioned above.
Really the only time destruction of the session should be delayed is when a
BYE is being transacted. This is because it's possible in some cases for the
session to be disconnected, but the BYE is still transacting.
This patch makes it so the session object always gets released (no more
memory leak) when the pjsip session is in a disconnected state. Except when
the method is a BYE. Then it waits until a transport error occurs or an event
timeout.
cdr_object_update_party_b_userfield_cb() could overrun the fixed buffer if
the supplied string is too long. The long string could be supplied by
external means using the CDR(userfield) function.
This may seem reminiscent to AST-2017-001 (ASTERISK_26897) and it is. The
earlier patch fixed the buffer overrun for Party A's userfield while this
patch fixes the same thing for Party B's userfield.

AST-2017-009: pjproject: Add validation of numeric header values
Parsing the numeric header fields like cseq, ttl, port, etc. all
had the potential to overflow, either causing unintended values to
be captured or, if the values were subsequently converted back to
strings, a buffer overrun. To address this, new "strto" functions
have been created that do range checking and those functions are
used wherever possible in the parser.
* Created pjlib/include/limits.h and pjlib/include/compat/limits.h
to either include the system limits.h or define common numeric
limits if there is no system limits.h.
* Created strto*_validate functions in sip_parser that take bounds
and on failure call the on_str_parse_error function which prints
an error message and calls PJ_THROW.
* Updated sip_parser to validate the numeric fields.
* Fixed an issue in sip_transport that prevented error messages
from being properly displayed.
* Added "volatile" to some variables referenced in PJ_CATCH blocks
as the optimizer was sometimes optimizing them away.
* Fixed length calculation in sip_transaction/create_tsx_key_2543
to account for signed ints being 11 characters, not 9.

res_pjsip_registrar.c: Fix named AOR and pjproject group deadlock.
One of the patches for ASTERISK_27147 introduced a deadlock regression.
When the connection oriented transport shut down, the code attempted to
remove the associated contact. However, that same transport had just
requested a registration that we hadn't responded to yet. Depending
upon timing we could deadlock.
* Made send the REGISTER response after we completed processing the
request contacts and released the named AOR lock to avoid the deadlock.

CLI: Remove unused internal command.
The internal CLI command "_command complete" was last used by Asterisk
0.2.0. Since then we've been using "_command nummatches" and "_command
matchesarray".
When (v)asprintf() fails, the state of the allocated buffer is undefined.
The library had better not leave an allocated buffer as a result or no one
will know to free it. The most likely way it can return failure is for an
allocation failure. If the printf conversion fails then you actually have
a threading problem which is much worse because another thread modified
the parameter values.
* Made __ast_asprintf()/__ast_vasprintf() set the returned buffer to NULL
on failure. That is much more useful than either an uninitialized pointer
or a pointer that has already been freed. Many uses won't have to check
for failure to ensure that the buffer won't be double freed or prevent an
attempt to free an uninitialized pointer.

ast_asprintf().
