There are 3 separate changes here but they are all closely related:

* Only try to set matchfield attributes on 'field' nodes

* We need to adjust how we treat the category pointer based on the
  value of the category_match, to avoid memory corruption. We now
  generate a regex-like string when match types other than
  ACO_WHITELIST and ACO_BLACKLIST are used.

* Switch app_agent_pool from ACO_BLACKLIST_ARRAY to
  ACO_BLACKLIST_EXACT since we only have one category we need to
  ignore, not two.

Change-Id: I7be7bdb1bb9814f942bc6bb4fdd0a55a7b7efe1e

Adds an information element for ANI2 so that
Originating Line Information can be transmitted
over IAX2 channels.

Currently pbx_ael does not check if a reload is currently pending
before proceeding with a reload. This can cause multiple threads to
operate at the same time on what should be mutex protected data. This
change adds protection to reloading to ensure only one ael reload is
executing at a time.

Change-Id: I5ed392ad226f6e4e7696ad742076d3e45c57af35

Allows for the digit # to be read as a digit,
just like any other DTMF digit, as opposed to
forcing it to be used as an end of input
indicator. The default behavior remains
unchanged.

This allows the STUN server to change its IP address without having to
reload the res_rtp_asterisk module.

The refresh of the name resolution occurs first when the module is
loaded, then recurringly, slightly after the previous DNS answer TTL
expires.

Change-Id: I7955a046293f913ba121bbd82153b04439e3465f

The attended transfer feature will emit a warning if the user
cancels the transfer or the attended transfer doesn't complete
for any reason. Changes the warning to a verbose message,
since nothing is actually wrong here.

ASTERISK-29612 #close

Change-Id: I64c93cdb21360a0a8d45e9cb6db3af8168f66e6d

Prevents reloads of app_queue from also resetting
queue statistics.

Also preserves individual queue agent statistics
if we're just reloading members.

This changeset is intended to address compatibility issues encountered
when interfacing Asterisk to electromechanical telephone switches that
implement ANI-B, ANI-C, or ANI-D.

In particular the behaviours that this impacts include:

 - FGC-CAMA did not work at all when using MF signaling. Modified the
   switch case block to send calls to the correct part of the
   signaling-handling state machine.

 - For FGC-CAMA operation, the delay between called number ST and
   second wink for ANI spill has been made configurable; previously
   all calls were made to wait for one full second.

 - After the ANI spill, previous behavior was to require a 'ST' tone
   to advance the call.  This has been changed to allow 'STP' 'ST2P'
   or 'ST3P' as well, for compatibility with ANI-D.

 - Store ANI2 (ANI INFO) digits in the CALLERID(ANI2) channel variable.

 - For calls with an ANI failure, No. 1 Crossbar switches will send
   forward a single-digit failure code, with no calling number digits
   and no ST pulse to terminate the spill.  I've made the ANI timeout
   configurable so to reduce dead air time on calls with ANI fail.

 - ANI info digits configurable.  Modern digital switches will send 2
   digits, but ANI-B sends only a single info digit.  This caused the
   ANI reported by Asterisk to be misaligned.

 - Changed a confusing log message to be more informative.

When playing a remote sound file, which is not in cache, first we need
to download it with ast_bucket_file_retrieve.

This can take a while if the remote host is slow. The current CURL
timeout is 180secs, so in extreme situations, it can take 3 minutes to
return.

Because ast_media_cache_retrieve has a lock on all function, while we
are waiting for the delayed download, Asterisk is not able to play any
more files, even the files already cached locally.

Change-Id: I8d4142b463ae4a1d4c41bff2bf63324821567408

Allow mapping pjproject log messages to the Asterisk TRACE
log level.  The defaults were also changes to log pjproject
levels 3,4 to DEBUG and 5,6 to TRACE.  Previously 3,4,5,6
all went to DEBUG.

ASTERISK-29582

Change-Id: I859a37a8dec263ed68099709cfbd3e665324c72d

The Milliwatt application uses incorrect tone timings
that cause it to play the 1004 Hz tone constantly.

This adds an option to enable the correct timing
behavior, so that the Milliwatt application can
be used for milliwatt test lines. The default behavior
remains unchanged for compatability reasons, even
though it is incorrect.

The MIN, MAX, and ABS functions all support float
arguments, but currently return floats even if the
arguments are all integers and the response is
a whole number, in which case the user is likely
expecting an integer. This casts the float to an integer
before printing into the response buffer if possible.

Previously, the Morsecode application only supported international
Morse code. This adds support for American Morse code and adds an
option to configure the frequency used in off intervals.

Additionally, the application checks for hangup between tones
to prevent application execution from continuing after hangup.

ASTERISK-29541

Change-Id: I172431a2e18e6527d577e74adfb05b154cba7bd4

Adds a function to scramble audio on a channel using
whole spectrum frequency inversion. This can be used
as a privacy enhancement with applications like
ChanSpy or other potentially sensitive audio.

ASTERISK-29542

Change-Id: I01020769d91060a1f56a708eb405f87648d1a67e

A list of codecs to use for dialplan-originated calls can
now be specified in Originate, similar to the ability
in call files and the manager action.

Additionally, we now default to just using the slin codec
for originated calls, rather than all the slin* codecs up
through slin192, which has been known to cause issues
and inconsistencies from AMI and call file behavior.

Change-Id: I96a1aeb83d54b635b7a51e1b4680f03791622883

Commit 305ce3de added -Wno-parentheses-equality to Makefile.rules,
turning the previous two warning suppressions from commit e9520dbe
redundant. Let us remove the latter.

Change-Id: I0b471254b31e6e05902062761dded4b3e626c7ac

Adds replacement modules to the moduleinfo for
chan_alsa and chan_sip.
