The handling of stream topologies was not protected by channel locks in
simple_bridge_request_stream_topology_change().

* Fixed topology handling to be protected by channel locks where needed in
simple_bridge_request_stream_topology_change().

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.

pjsip_distributor:
   authenticate() creates a tdata and uses it to send a challenge or
   failure response.  When pjsip_endpt_send_response2() succeeds, it
   automatically decrements the tdata ref count but when it fails, it
   doesn't.  Since we weren't checking for a return status, we weren't
   decrementing the count ourselves on error and were therefore leaking
   tdatas.

res_pjsip_session:
   session_reinvite_on_rx_request wasn't decrementing the ref count
   if an error happened while sending a 491 response.
   pre_session_setup wasn't decrementing the ref count if
   while sending an error after a pjsip_inv_verify_request failure.

res_pjsip:
   ast_sip_send_response wasn't decrementing the ref count on error.

It was discovered that there are some corner cases where a pjsip tsx
might have no last_tx so calling ast_sip_failover_request with
a NULL last_tx as its tdata would cause a crash.

When receiving a SUBSCRIBE request the Accept headers from it are
stored locally. This operation has a fixed limit of 32 Accept headers
but this limit was not enforced. As a result it was possible for
memory outside of the allocated space to get written to resulting
in a crash.

This change enforces the limit so only 32 Accept headers are
processed.

When an RTP packet is received by an RTP engine it has to map the
payload into the Asterisk format. The code was incorrectly checking
our own static list for ALL payloads if it couldn't find a negotiated one.
This included dynamic payloads. If the payload mapped to a format
of a different type (for example receiving a video packet on an audio
RTP instance) then the core stream code could cause a crash if a legacy
channel driver was in use as no stream would be present.

To provide further protection the core stream code will no longer assume
that a video or audio frame will always have a stream for legacy channel
drivers. If no stream is present the frame is dropped.

This will make the source filename match the 'module reload sounds'
command.  This will allow conversion to a built-in module in Asterisk 16
without needing to redefine AST_MODULE.

Expand locking to include full reload process for extconfig to ensure
nothing can read the config mappings between clearing and reloading.

 * Prefer strcasecmp() over stricmp()
 * Use a list with no lock since we never actually lock
 * Minor cleanups to error messages

This causes the root bootstrap.sh script to generate configure scripts
for both Asterisk and menuselect.  This ensures that both configure
scripts are generated with the same version of autotools and avoids
situations where shared autoconf macros get modified without
regenerating the menuselect script.
