The error path frees all side data, but forgets to reset the side data
count. This can blow up later in av_frame_unref() and free_side_data().

This change make error handling simplier.
av_opt_freep_ranges may be called when some ranges are NULL,
for example after memory allocation fail.

This is incompatible with libavcodec version
55.18.100 to 55.43.100 except 55.39.101
This incompatibility is caused by these libavcodec versions depending on
a libavutil 52 which is ABI incompatible with the previous ABI 52
you can avoid this incompatibility by upgrading your libavcodec so it
does no longer depend on the invalid ABI

The new syntax is preferred since it allows backward syntax compatibility
with libswr when switching to the new option handling code with
AV_OPT_TYPE_CHANNEL_LAYOUT.
With the new parser the string:
1234
is interpreted as a channel layout mask, rather than as a number of
channels, and thus it's compatible with the current way to set a channel
layout as an integer (e.g. for the icl and ocl options) making use of
integer option values.
ff_get_channel_layout() with compat=0 will be used in the
AV_OPT_TYPE_CHANNEL handler code.
The user is encouraged to switch to the new forward compatible syntax,
which requires to put a trailing "c" when specifying a layout as a number
of channels.
This makes sure that pointers from av_strdup are reallocable,
which is used in av_dict_set if the AV_DICT_APPEND flag is set.
Nothing should rely on pointers from av_strdup being aligned.

x86inc: Use VEX-encoded instructions in AVX functions
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This is so we can sync to x264's version of FMA4 support.
This partialy reverts commit 79687079a9.

Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4
functions for all instructions that exists in a VEX-encoded
version.
This change makes it easier to extend existing code to use AVX2.
Also add support for AVX emulation of a few instructions that
were missing before.
