Repository: Asterisk


Description
-------

This patch performs the renaming discussed on the asterisk-dev list [1]. As usual, as I was going through it some other cleanups occurred, and in order to make sure I didn't make memory leaks worse, some parts of Corey's memory leak cleanups made their way in as well.

[1] http://lists.digium.com/pipermail/asterisk-dev/2014-June/068133.html

The great renaming:

 * ast_format_cap_add             => ast_format_cap_append
 * ast_format_cap_add_all_by_type => ast_format_cap_append_all_by_type
 * ast_parse_allow_disallow       => ast_format_cap_update_by_allow_disallow
 * ast_cap_remove_bytype          => ast_format_cap_remove_by_type
 * ast_getformatname_multiple     => ast_format_cap_get_names, and now uses an ast_str ** instead of a char *buf/size_t len
 * ast_format_sdp_generate        => ast_format_generate_sdp_fmtp
 * ast_format_sdp_parse           => ast_format_parse_sdp_fmtp

Functions removed:
 * ast_format_compatibility_get_original_id - no longer used

Note that chan_h323, chan_gtalk, and chan_jingle did not get all of the re-namings (particularly ast_getformatname_multiple => ast_format_cap_get_names), and will not compile with this patch. These modules should be removed, per the discussion on the -dev list.

Functions that support REF_DEBUG:
 * ast_format_cap_alloc
 * ast_format_cap_append
 * ast_format_cache_get

Memory leak cleanups (many of which came from Corey's patches):
 * Channel technology struct capabilities leak their format capabilities on off nominal exit paths (chan_motif, chan_pjsip, chan_unistim, chan_skinny)
 * Format capabilities leak in chan_pjsip_new nominal path
 * Leak of nativeformats format_cap in nominal path of channel.c's ast_channel_alloc
 * Leak of format_cap in channel.c's set_format
 * Leak of format_cap in channel.c's ast_request
 * Usage of ao2_replace in translate.c to avoid overwriting a ref
 * Clean up of frame format cache in RTP instance in res_rtp_asterisk destructor

Unit tests
 * Remove test for ast_getformatname_multiple, add test for ast_format_cap_get_names

Testing
-------

Negotiation using PJSIP still works.

The most prevalent memory leak that still occurs happens when a statically allocated frame ref bumps a format. This happens a lot when generating translator tables, and in various other places as well.


Thanks,

Matt Jordan
