Define types of packetizers, with dedicated init and destroy functions,
and move maintenance of sample stream into encoder

In case of bitstream style codecs which still use an encoder which
operates on fixed frame sizes (e.g. G.726), passing the maximum allowed
frame/packet size to the packetizer is not enough. Instead it needs to
know separately how much data it is expected to return. Add another
argument to pass this information.
This also fixes the incorrect math to adjust the frame duration in case
of chunked output.

... from packetizer function instead of putting it into the AVPacket.
Remove AVPacket from callback function arguments.
Fix up PTS/duration adjustments where they were missing.

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.

In some cases, in particular when multiple input codecs are transcoding
to the same output codec (e.g. audio + DTMF -> audio), it's possible
that one of the input decoders produces frames in a format different
from the one expected by the encoder. Add an encoder-side resampler to
compensate for that.

ffmpeg 7.1+ has deprecated direct usage of ->sample_fmts in favour of a
call to avcodec_get_supported_config(). Update accordingly.

Add support for simplified G.107 formula, with math changed to
fixed-point. Retain legacy formula as an option for backwards
compatibility.

Switch all memory buffers used for RTP I/O from generic stack or heap
allocated memory to the bufferpool implementation. Use a per-thread
bufferpool to minimise lock contention.
This commit is just a one-for-one swap and doesn't use the bufferpool's
reference counting semantics yet.

As we don't directly append to an existing GString any more anyway,
simplify the function signature by just returning a new GString if the
format string is known.

Introduce rtpe_has_cpu_flag() and associated enum to test for specific
CPU flags. Use singleton approach to do the CPUID only once.
Convert simd_float2int16_array() to float2int16_array() as an ifunc. The
resolver function uses rtpe_has_cpu_flag() to determine which
implementation to use.
If no SIMD implementation is available, use the linked evs_syn_output()
from the shared object as before, with an intermediate wrapper function,
which is needed as the dlopen() happens only after the
float2int16_array() is resolved.

Prevent a wrongly advertised (too small) a=ptime from producing too
small buffers to hold encoded packets by flagging codecs with a fixed or
minimum frame size as such.
This is relevant to libavcodec only as the code determines the expected
frame size from the clock rate and the ptime.

This type is used as const everywhere except internally, so make it part
of the typedef for brevity.

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.
