Introduces ice_blacklist configuration in rtp.conf. Subnets listed in the
form ice_blacklist = <subnet spec>, e.g. ice_blacklist =
192.168.1.0/255.255.255.0, are excluded from ICE host, srflx and relay
discovery. This is useful for optimizing the ICE process where a system
has multiple host address ranges and/or physical interfaces and certain
of them are not expected to be used for RTP. Multiple ice_blacklist
configuration lines may be used. If left unconfigured, all discovered
host addresses are used, as per previous behavior.

Documention in rtp.conf.sample.

CDRs form chains. When the root of the chain is destroyed, it then
unreferences the next CDR in the chain. That CDR is destroyed, and it
then unreferences the next CDR in the chain. This repeats until the end
of the chain is reached. While this typically does not cause any sort of
problems, it is possible in strange scenarios for the CDR chain to grow
way longer than expected. In such a scenario, the destruction pattern
can result in a stack overflow.

This patch fixes the problem by switching from a recursive pattern to an
iterative pattern for destruction. When the root CDR is destroyed, it is
responsible for iterating over the rest of the CDRs and unreferencing
each one. Other CDRs in the chain, since they are not the root, will
simply destroy themselves and be done. This causes the stack depth not
to increase.

Since Asterisk 1.8, the command "core set debug" on the command-line interface
asks not for a file (.c) but a module name. This change shows modules (.so) on
the auto-completion via a tabulator or the question mark. Now, when you
partially type a module name, TAB or ?, you get the correct candidiates.

When using Asterisk Realtime Architecture, empty fields are skipped and the
default values are used. If the "context" parameter in queue was set and then
cleared from the database, the old value remains in memory and it continues
to be used. This change initialize the "context" parameter with an empty value,
allowing clearing the parameter.

This patch adds the Asterisk EID field to all outgoing ARI events.
Because this field should be added to all events as they are
transmitted, it is appended to the JSON message just prior to it being
handed off to the application message handler. This makes it somewhat
resilient to both new events being added to ARI, as well as other
potential event transport mechanisms.

ast_set_default_eid was searching for ethX, emX, enoX, ensX and even
pciD#U interface names.  While this was a good attempt, it wasn't
inclusive enough to capture interfaces like enp6s0 or ens6d1, etc.

Rather than relying on interface names, we now simply find the first
interface returned by the OS that has a hardware address and that
address isn't all 0x00 or all 0xff.  The code IS different for BSD,
Solaris and Linux based on what method is available for enumerating
interfaces.

Tested on:
FreeBSD9
CentOS6
Ubuntu14
Fedora24

I was unable to test on Solaris at this time but the code for Solaris
is used elsewhere at Digium.

Previously, the settings videosupport=always and videosupport=yes behaved
identically and unconditionally caused a video offer to be sent in the SDP on
an outgoing call. This was a regression introduced with commit
5a1d90e1 in Asterisk 1.6.1.

This commit restores correct behavior: videosupport=always causes a video offer
to be sent unconditionally, while videosupport=yes will only offer video on an
outbound channel if the incoming channel it is bridged to also supports video.
That way, the device receiving the outgoing call can display the correct user
interface elements for audio or video and will not unnecessarily show a blank
video window on an audio-only call.

Previously when testing I had a preexisting makeopts in ASTTOPDIR.  The
ordering of configure.ac causes --with-externals-cache to be processed
after third-party configure.  In cases where the Asterisk clone is
cleaned it would cause pjproject to be downloaded to /tmp.  This
moves processing of the externals cache and sounds cache to happen
before third-party configure.

This also addresses a possible issue with the third-party Makefile.  If
TMPDIR is set by the environment it would override the path given to
--with-externals-cache.

Unlike any of the other database drivers, res_config_mysql checks that
the table definition matches the requirements for every insert and
update statement.  Since all requirements are forced to 'char', any
column that isn't a char, like ps_contacts' expiration_time,
qualify_timeout, etc., will throw a warning.  It's kinda harmless but
very misleading.  Since no other driver does those checks on insert
or update, they've been removed from res_config_mysql.  Also, all
the logic that actually attempted to ALTER the table to fix the issue
has been removed.  With the move to alembic, the auto-alter
functionality is not only unnecessary, it's also dangerous.

The other issue is that res_config_mysql calls the mysql_insert_id
function inside store_mysql.  Presumably the intention was to return
the number of rows inserted DESPITE A NOTE IN THE CODE THAT THE VALUE
IS NON_PORTABLE AND MAY CHANGE.  That value is then returned to
config realtime as the number of rows inserted.  Guess what?  The value
changed.  It now only returns the number of rows inserted if there's an
auto increment column on the table, which ps_contacts doesn't have.
Otherwise it returns 0.  So now, the insert worked but we tell config
realtime and sorcery that no rows were inserted.  That call to
mysql_insert_id was removed and we now always return 1 if the insert
succeeded.  We're only inserting 1 row at a time anyway.  If the insert
fails, we still return -1.
