Apparently the compiler sometimes bypasses the normal assembler, in
which case the asm label variant works.  If the file contains any
inline asm, this bypassing is not done, and the assembler chokes on
invalid syntax.  Inserting a dummy asm() statement in the test when
the compiler supports it makes sure no shortcuts are taken and the
test fails as it should.

When symbol versioning is enabled, moving symbols from one library to
another breaks binary compatibility.  This adds wrappers with the old
version tag for the av_*packet functions recently moved to lavc.

Since the parsing of Vorbis/Theora fmtp headers is handled by the
parse_sdp_a_line function pointer now, the buffer in sdp_parse_fmtp
doesn't need to be this large any longer.

This interrupt parsing and goes one ebml level up when encountering
a cluster start inside an unknown sized element which is not supposed to
contain a cluster.
fix issue1991

Originally committed as revision 23589 to svn://svn.ffmpeg.org/ffmpeg/trunk

Now that we save the currently parsed ebml element ID after an interruption,
we don't need to special case the parsing of the first cluster.

This allows to interrupt parsing after reading an ID, and then properly
recover parsing.
