Similar to the existing media_player, but instead of simply producing
its own standalone output media stream, the audio_player takes over the
entire media stream flowing to the receiver, including media forwarded
from the opposite side of the call, as well as media produced by the
media_player.

A simple circular audio buffer that allows mixing multiple sources of
audio. Sources are tracked by SSRC and all sources are expected to
provide audio in the same format (same clock rate, channels, sample
format).
Only one consumer per buffer is supported, which is expected to retrieve
buffered audio at regular intervals (ptime) and so continuously empty
the buffer.
The first audio source to write into the buffer at the leading edge of
the circular buffer has its audio simply copied into the buffer, with
the leading edge advanced, while other later sources writing into the
buffer mixed into the existing buffered audio at their respective write
positions.

Instead of going through ffmpeg to en/decode Opus, use libopus directly,
which allows us to benefit from additional features that aren't
available when going through ffmpeg.

These tests are timing sensitive which makes them unstable under certain
conditions. Remove them from the automated build system.

Complete overhaul of the codec handling code:
*) obsolete flags `asymmetric codecs`, `symmetric codecs`, `reorder
codecs`
*) support proper codec offer/answer
*) split codec manipulation (strip/offer/accept/etc) into separate
functions for clarity and better code maintenance
*) fully update codec handlers in both directions after an answer
*) explicit allocation and handling of codecs and payload types in a
codec_store object
*) improve codec matchup logic during answer
*) more explicit handling of supplemental codecs (CN/DTMF)
*) remove now obsolete hacks for handling certain use cases

We should eventually try to reduce the amount of -Wno-* options, but for
now this is a net improvement.

Since dh_auto_test doesn't execute the test suites through make
directly, but instead runs `make -s -n` and then executes the output,
the integrated build tests fail since the sub-make doesn't return an
error as it should when attempting to build with the wrong .h
alternative, resulting in always the first .h alternative being used.
Fix this by using a wrapper script instead.
Also adjust some other related minor build details.

Rename test suites from *-test.c to test-*.c as the former is
conflicting with the file name pattern of the build tests, which are
listed in .gitignore.

crypto.c: handle 12 bytes master salt length of AEAD
AEAD RFC7714 specifies 12 bytes master salt length
(section 12) but the KDF expects 14 bytes.
The erratum to RFC7714 specifies to pad on the right
by 16 bits to be compliant with the KDF.
