12e1e83461 lavc: set channel count from channel layout in avcodec_open2(). 
Some decoders (e.g. nellymoser) only set channel_layout and do not set
channel count.

d16860a237 libopus: Remap channels using libopus' internal remapping. 
This way we can directly remap channels from Opus' channel order to
libav's internal channel order, instead of mapping channels from
Opus' order to Vorbis' order then to libav's order.

92d2b909a0 xsub: feed init_get_bits the whole buffer 
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.

Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

c54e00610f sipr: fall back to setting mode based on bit_rate. 
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.

a34a609fc1 motion_est: fix use of inline on extern functions 
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.

5e997688f8 h264: Remove an assert on current_picture_ptr being null 
It is possible in various error paths as well as gap handling
that this has already been allocated. It is not clear why that
would be a problem with the current code, thus disable the
assert to avoid a common assert failure when asserts are enabled.

aa264da5bf adpcmenc: Calculate the IMA_QT predictor without overflow 
Previously, the value given to put_bits was 10 bits long for positive
predictors, even though 9 bits were to be written. The extra bit could
in some cases overwrite existing bits in the bitstream writer cache.

This fixes a failed assert in put_bits.h, when running a version
built with -DDEBUG.

The fate test result gets slightly improved, thanks to getting rid
of the overwritten bits in the bitstream writer cache.

a4b8fc3a8a g723.1: simplify normalize_bits() 
This function is always called with a non-negative argument, so
those special cases are not needed.  In the places the argument
might be zero, the return value for a zero argument does not matter
since it would then be used to scale an array full of zeros.
