Adds a new config section that allows adjusting behaviour for certain
transcoding scenarios. This only adds the initial support for the config
option.

Special codec handler to support not forwarding (nor any processing
whatsoever) of particular payload types at all. Support this in the
kernel module as well.

Obsolete the two flavours of packet_encoded_tx and instead distinguish
the two flavour of sequence number handling (passthrough and
self-generated) through a function pointer in the codec SSRC handler,
directly pointing to one of the two existing codec_output_rtp wrappers.

Make sure a codec is not only known to us, but that it can actually be
used, in places where it makes sense. This is partially redundant
because ensure_codec_def_type already takes care of this, but a codec
definition may come from a different source, so it doesn't help to
double check.

A matching payload type number in an answer might not be enough to
establish compatible codecs. Also check the format parameters. Reject
and ignore answer codecs that are not compatible.

`packet_sequencer_init()` initializes
`packet_sequencer_t` sequence to -1 always.
So make sure to set `uint16_t` later not to
an underflowing value, which can potentially
set the `uint16_t` object type to some insanely
big value.

Make the macro return the appropriate pointer type, and make sure the
free function takes an argument of the same type. This also eliminates
some boilerplate type-casting code.

The `answer` processing empties out the list of codecs and leaves only
those that were accepted in the answer. Side effect of this is that if
another answer with a different list of codecs comes through, them the
codec-accept function is missing the original list of offered codecs and
can yield an incorrect result.
Fix this by storing a copy of the offered codecs at the end of the
`offer` processing, and then restore this list at the beginning of each
`answer` message.

In many transcoding scenarios resampling is not actually required. We
can shortcut the operation by just returning the original frame, instead
of a cloned and newly allocated one. We just need to distinguish between
the cases to determine whether the frame returned by resample_frame()
needs to be freed.

Remove all codecs that cannot be transcoded to when the audio player is in
use.
Add safety to make_transcoder to return failure in case an unsupported
codec is requested for transcoding.
Convert leftover passthrough handlers to SSRC passthrough if there are
any (shouldn't be).

Obsolete str_init(), rename STR_INIT() to just STR(), and replace all
instances of str_init() with STR().

For typed hash tables, enforce the correct type in the arguments to the
hashing and equality functions.
Adapt existing affected callback functions and change their arguments
from void* to the respective types.
Add reverse casts to GHashFunc and GEqualFunc in instances where these
functions are used in non-typed hash tables (that should be converted at
a later point).
Add convenience macro to create typed wrapper functions for hash tables
that use "direct" hashing (i.e. the pointer value).
Add wrappers for existing GLib functions that have generic arguments so
that they can be used in typed hash tables.

There isn't any immediate benefit to this, but it prepares the code for
use of shared memory for statistics.
Use the opportunity to switch accesses to these to relaxed memory order.
