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

Per RFC 4867 section 8.1, absent fmtp parameters imply defaults (bandwidth-efficient mode, no CRC,
no robust-sorting, no interleaving). Previously, codec matching was rejected when either side had no
``a=fmtp`` attribute for the AMR payload type, causing AMR to be dropped as a "stray answer codec".
This patch changes this behavior to instead "parse" fmtp even when absent so that the format struct
is populated with zero-initialized defaults and fmtp_parsed is set.

ffmpeg's CNG expects a fixed frame size, or at least a maximum frame
size, as it allocates internal buffers on construction based on that
frame size. Calling the decoder with a larger frame size therefore leads
to an internal buffer overflow. Calling it with a smaller frame size is
fine.
Retain the simple one-shot CNG for the most common case (frame size
smaller than the max). For larger frames, call the CNG in a loop and
manually construct a return frame.

Add RED (RFC 2198) codec definition to codeclib as a supplemental codec.
Modify codec_store_accept_one() to preserve supplemental codecs whose
clock rate matches the accepted primary codec. Skip supplemental codecs
in codec_store_is_full_answer() since they are optional in SDP answers.

The ffmpeg G.726 encoder operates on fixed frame sizes which don't
reflect the expected frame size on the wire. Add an encoder init wrapper
to set the correct frame size.

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.

RFC says that annex B is the default in the absence of the annexb=no

The GLib slice allocator has been obsoleted. Having a mixture of two
allocators can lead to hidden issues on systems that use different
implementations. Take the leap and replace everything with g_new/g_free.
