The new library is meant to contain the core multimedia utilities for
FFmpeg, to make them shareable between more libav* libraries.

This test verifies the pixdesc code by comparing the output with and
without a filter which should have no effect on the image.  Since the
available pixel formats depend on the byte order of the machine, a
simple reference checksum is not possible.

The test originally tried to solve this by generating a reference file
on the fly.  The problem with this is that the test framework expects
the reference file in the source tree, and writing to the source tree
is not allowed.

To avoid complicating the test framework, we instead provide two
reference files and select which to use based on the byte order.

The AAC decoder and ADTS-to-ASC BSF both require the header decoder
but not full parsing capabilities.

Remove check for an specific w32api version, checking instead if vfw.h
supports vfw capture. The defines in w32api 3.12 were wrong, so this must be
accounted for in the check.

Check for GNU assembler only when asm is enabled.  Show a warning for

This functionality is better accessed through tools like oprofile.

Originally committed as revision 23808 to svn://svn.ffmpeg.org/ffmpeg/trunk

gprof is far too intrusive to be of use as a profile for ffmpeg,
and it fails to build in many configurations.  Oprofile is a
better tool for profiling on Linux.
