6221e2478c parseutils: fix parsing of invalid alpha values
An alpha specifier outside the valid range results in a conversion from
double to long with undefined result.  Range-checking the double and
only converting it after it passes avoids this.

Fixes fate-parseutils errors on some systems.

a7329e5fc2 x86: get_cpu_flags: add necessary ifdefs around function body
ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined
elsewhere in the file.  Surrounding the function body with ifdefs allows
building even when cpuid is not defined.  An empty cpuflags mask is
returned in this case.

a4d71eb5c3 random_seed: Only read /dev/*random if we have unistd.h
unistd.h is used for open/read/close, but if this header does not
exist, there's probably no use in trying to open /dev/*random
at all.

5b170c0bea x86: remove FASTDIV inline asm
GCC 4.3 and later do the right thing with the plain C code.  Earlier
versions in 32-bit mode generate one extra instruction, needlessly
zeroing what would be the high half of the shifted value.  At least
two gcc configurations miscompile the inline asm in some situations.

In 64-bit mode, all gcc versions generate imul r64, r64 followed by
shr.  On Intel i7 and later, this imul is faster 32-bit mul.  On
older Intel and all AMD, it is slightly slower.  On Atom it is much
slower.

Considering where the FASTDIV macro is used, any overall negative
performance impact of this change should be negligible.  If anyone
cares, they should file a bug against gcc and get the instruction
selection fixed.

6c4975eaaf libavutil: add saturating addition functions
Fixed-point audio codecs often use saturating arithmetic, and
special instructions for these operations are common.

It appears that something goes wrong in old nasm versions when the

this argument is tested with %ifdef within the macro.  This patch
rearranges the macro arguments such that the %+ operator is never
used in the last argument.

239fdf1b4a x86: build: replace mmx2 by mmxext
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.
