x86/dct32: don't build ff_dct32_float_sse on x86_64
...
There's an SSE2 version already, and technically the SSE version
on x86_64 was wrong (using pshufd and pshuflw, SSE2 instructions).

our vorbis decoder entirely independent of dsputil.

Globally rename the header inclusion guard names.
...
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
