d433e1aefa mem: Make av_strdup allocate using av_realloc 
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.

c108ba0175 x86inc: Use VEX-encoded instructions in AVX functions 
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.

3e2fa991db x86inc: remove misaligned cpu flag 
Prevents a crash if the misaligned exception mask bit is
cleared for some reason.

Misaligned SSE functions are only used on AMD Phenom CPUs
and the benefit is miniscule. They also require modifying
the MXCSR control register and by removing those functions
we can get rid of that complexity altogether.

25cb0c1a1e x86inc: activate REP_RET automatically 
Now RET checks whether it immediately follows a branch, so the
programmer dosen't have to keep track of that condition. REP_RET
is still needed manually when it's a branch target, but that's
much rarer.

The implementation involves lots of spurious labels, but that's OK
because we strip them.

d5b58f678d tools: add benchmark for crypto functions. 
The benchmark tests the speed of the following algorithms:
MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128.

It can optionally be built to perform the same benchmark on
other crypto libraries, for comparison purposes.
The supported libraries are:
- crypto:   OpenSSL's libcrypto;
- gcrypt:   GnuTLS's libgcrypt;
- tomcrypt: LibTomCrypt
To enable them, use this syntax:
make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench
They do not need to have been enabled in configure.

9116995efb libavutil: add AV_PIX_FMT_BAYER pixel formats 
The pixel format descriptors are set to more or less arbitrary
values as bayer formats do not fit in the descriptors structure.
These values are currently not used for bayer formats and thus
do not matter.
