This is faster for videos that have lots of MBs that fall in this category.

This is consistent with other codecs and will also avoid a crash on the
memcpy to data[1] if AVPALETTE_SIZE ever increases.

Fixes encoder crashes e.g. with MPlayer's -vf lavc.

if present. This fixes playback of a number of MS-RTSP streams, mostly these
for which playback contains a session key in the URI. Fixes issue 1697.

This compiler supports gcc-style alignment attributes for struct,
but not for global variables. For the latter, alignment can be
specified with a pragma, which does not work for struct members or
local variables. By using both pragma and attribute, one or the
other will always take effect.
Unfortunately, no means exists for aligning stack variables.

The seemingly equivalent _Pragma(AV_STRINGIFY(x)) is not accepted
by some compilers.

Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

This should be faster (couldnt meassue a difference), and its less picky
on slightly out of spec dquant.

The macro implementation might need the name of the variable being
declared for compiler-specific syntax. Moving array specifiers outside
the macro invocation allows this to work.

formats with only one stream; the AVFormatContext values will be derived from
the AVStream and this helps in calculating stream bitrate.

The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count. This allows -threads 0
to pass through to codecs. It also simplifies the usage for apps
using libavcodec.
