RTP packet without any extra header bytes.

Do not use rlelen field for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.

This avoids using the global_quality field and QSCALE flag for
passing the VBR modes, since the value range of the global_quality
field doesn't really map cleanly to this codec's VBR modes.

These modes were not originally exposed by the library at all.
In practice, only a few of them work for each sample rate/profile
combination, and they don't work at all for the more uncommon
sample rates.

The fisbone packets can be muxed in any order as long the last one
comes before the first data packet.

Not having the header for a codec is a tell-tale of a broken file.

This allows using avcodec_free_frame() to free it properly.

Since an AVFrame now has malloced members (extended_data), it must have
a destructor.

Otherwise the frame is uninitialized, so avcodec_get_frame_defaults()
cannot determine whether to free extended_data.

AVFrame is used for both audio and video, so calling the argument 'pic'
is misleading.

This is required in chained muxers, if the SAR happens to be set.

Ensure that padded_frame is freed before returning when needed.

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned.  Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.

This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is
called with a zeroed AVProbeData since no packet made through for
specific stream.

Inline functions declared without extern do not provide an external
definition in standard C99.  This code only works because most
compilers do not implement the inline semantics correctly.  With a
stricter compiler, linking fails with unresolved references to these
functions.

Declaring the functions extern inline works correctly with some
compilers while some others still fail to create external definitions.

For maximum portability, create a static inline version with an
externally visible wrapper for ff_get_mb_score.  ff_epzs_motion_search
is so large that no sane compiler inlines it anyway, so there the
inline keyword can simply be dropped with no effect.
