c9e6325ed9 vp9/x86: use explicit register for relative stack references. 
Before this patch, we explicitly modify rsp, which isn't necessarily
universally acceptable, since the space under the stack pointer might
be modified in things like signal handlers. Therefore, use an explicit
register to hold the stack pointer relative to the bottom of the stack
(i.e. rsp). This will also clear out valgrind errors about the use of
uninitialized data that started occurring after the idct16x16/ssse3
optimizations were first merged.

fa20babb46 lavf/avienc: use metadata_header_padding 
The muxer will write at least the number of bytes requested and possibly
up to 3 bytes more.  This is because the muxer writes 32-bit integers
and the format requires 4-byte alignment anyway.

72eeb18468 lavf/flacenc: use metadata_header_padding 
Allows a user to control the amount, if any, of padding they want added
to the file.  If set to zero the block will not be written at all.  If
set to some positive number four more bytes will be added to the file
due to the small header required for the block.

86bee7984e AVFormatContext: add metadata_header_padding field 
This field is used to store the number of bytes that should be written
as padding to a metadata header of a file.  For example:
 - The FLAC format's METADATA_BLOCK_PADDING [1]
 - The ID3v2 tag format's padding           [2]

- The memcpy was completely wrong because
s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas
s->prob.coef is a [4][2][2][6][6][11] array.
