cli.c: Fix tab completion of "module load" when MALLOC_DEBUG is enabled.

filename_completion_function() returns memory that was not allocated by
the MALLOC_DEBUG allocation tracker so the memory must be freed by
ast_std_free().

chan_pjsip: Update media translation paths when new SDP negotiated.

On a SIP reinvite that changes media strams, the PJSIP channel driver was
flooding the log with "Asked to transmit frame type %s, while native
formats is %s" warnings.

* Fixes PJSIP not setting up translation paths when the formats change on
a reinvite.  AFS-63 was effectively reintroduced because of the media
formats work.  res_pjsip_sdp_rtp.c:set_caps()

* Improved the unexpected frame format WARNING message to include more
information.

* Added protective locking while altering formats on a channel.  Reworked
set_format() to simplify and protect the formats under manipulation.

* Restored some code that got lost in the media_formats work.
(channel.c:set_format() and res_pjsip_sdp_rtp.c:set_caps())

AFS-137 #close
