One more fix, because we only want ot split AVI's and not quicktime movies

linux doesn't (apaprently) require that mutex attribute structures be
initialized before use. OS/X _does_. It is necessary to "create" or "initialize"
a mutex attribute with:
pthread_mutexattr_init(&mu_attr);
before setting flags or using the mutex.

Updated to reflect latest changes.

nasm is no longer needed (no .s files remaining).

The last of the .s files is gone (Thanks Gert!). No need for special rules
in mpeg2enc/Makefile.am or for strip_fPIC.sh to exist.

Complete the error checking and adding diagnostic message on mutex lock/unlock
failure. So far this has produced (on OS/X) the following when mpeg2enc
is run with other than -M 0:

INFO: [mpeg2enc] Creating worker thread
2 pthread_mutex_lock=22

That message comes from channel.hh. error 22 is EINVAL which seems to point
at the 'atomic' mutex not being initialized. The manpage says:
[EINVAL] The value specified by mutex is invalid.

yet more instrumentation - basically if mutex lock/unlock detects an error
then emit a diagnostic before aborting (this is because gdb is almost
useless with threaded shared lib using programs).

More instrumentation to track down threading problems.

fdctdata.c is part of fdct_mmx.c, after conversion of fdct_mmx.s to inline asm

remove fdct_mmx.s (replaced by inline asm)
