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.

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.
