f1f792117f x86: use raw opcode for xgetbv instruction 
This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic.  These include clang and some BSD versions.

All AVX code will be written for yasm, where the main assembler
is not involved.

545dc699f8 Force inlining of avutil common routines 
On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files.  This is generally bad, as most of these
functions are smaller inlined than not.

40c3fe2c08 Deprecate parse_date() in favor of av_parse_time(). 
The new av_parse_time() is created in libavutil/parseutils.h, all the
internal functions used by parse_date are moved to
libavutil/parseutils.c and made static.

4cabef0a9d Make strmatch() return 1 only if the string compared against the 
prefix does not contain other characters which may belong to an
identifier.

This allows to distinguish for example to have different constants
with the same prefix (e.g. "foo" and "foobar").
