There are a lot of codecs these days, and some clients offer all of
them.  If we run out of space in this buffer our local SDP will get
silently truncated, which will cause a difficult to diagnose error in
Sofia-SIP.

Thanks to Anthony Minessale.

This error was causing us to call generate_m with a buffer length that
was less than the strlen of the buffer we were passing.  The result
was truncated local SDP which would cause sofia to fail if the
truncation was in a particularly bad place.

Thanks to Anthony Minessale for the fix and working with me to
diagnose the issue.

It's broken too many of my recent builds.  We can add it back in when
things stabilize or perhaps after we get it to swig with a recent
version of swig that we can make part of the clean bootstrap/build
process.

POSIX sed doesn't support grouping, so split the regex in two.

Speculative fix for a mod_python build issue on OSX, which is
caused by '-arch i386 -arch x86_64' in the final PYTHON_CFLAGS.

Filter both flags and hope OSX's universal binary toolchain is smart enough
to choose a sane default.
