This fixes use of uninitialized values when the FLAC encoder uses the
2-level, 4-level, and 8-level search methods. Fixes failure of the
fate-flac-24-comp-8 test when run using valgrind.

Fixes Bug 385

Also move a misplaced line from the 9_beta2 section to <next>

Previously the high end byte was always set to zero. Also get
rid of an unnecessary multiplication (which in practice couldn't
overflow) before shifting.

This allows getting rid of redundant checks later in the codec
specific init functions.

Move the check to before actually initializing the decoder lib,
to simplify error handling.

This fixes a case of returning a value from a void function, present since
d40dab90.

YASM accepts labels without colons, but NASM issues warnings.

This will distinguish FLAC 16-bit tests from FLAC tests with other bit
depths.

Also, templatize the functions for 16-bit and 32-bit sample range. This will
be used for 24-bit FLAC encoding.

Needed to avoid integer overflows for 24-bit encoding.

This is much faster than calculating the MD5 one sample at a time.

This fixes compilation with --disable-everything and components enabled.

A sentence was mistakenly inserted in the middle of another sentence.

The packet belongs to lavf, the caller must not free it or access it in
any other way.
No change in practice, since destruct is set to NULL anyway.

Useful for detection of subtitles displayed during foreign language
scenes.

"mmxext" is a more sensible name and more common in outside projects.
