lavu: add missing log.h include in timer.h
fate: force the simple idct for xvid custom matrix test

The original test without a forced idct is still useful since it tests
the switching of the idct algorithm/permutation on x86 with MMX. MMXext
or SSE2. Make sure the test runs only if MMX inline asm is available and
force -cpuflags to all.
Add the required bitexact flag for both tests.

vorbis: append data from tags together

Currently, if there are multiple 'performer' tags, the last one is the
only one which appears. Instead, join them with a semicolon.

vorbis: extract metadata from the middle of a stream

If a special comment packet shows up in the middle of the stream, we
should extract it out into the vorbis stream metadata dictionary.

Also, if there is metadata in the packet on the way in, it might linger
since we only add data to the dictionary causing stale metadata to be
inserted into the stream. Instead, clear it to remove any doubt about
what is new and old.

configure: Remove dcbzl check for e500v1 and e500v2 architectures

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we need to
remove the test for it explicitly for these architectures.
