7751e4693d ogg: check that the expected number of headers had been parsed 
Not having the header for a codec is a tell-tale of a broken file.

c084a975aa lavc: use av_mallocz to allocate AVFrames. 
Otherwise the frame is uninitialized, so avcodec_get_frame_defaults()
cannot determine whether to free extended_data.

a83499b13b lavc: rename the argument of avcodec_alloc_frame/get_frame_defaults 
AVFrame is used for both audio and video, so calling the argument 'pic'
is misleading.

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.

cdb7db5acd ARM: align PIC offset pools to 4 bytes 
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.

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.
