configure: more properly disable header when check_header_oc() fails

This should make no difference currently

configure: use TMPM in check_header_oc

Some compilers when given -x objective-c will tell that they dont support
that but return success. Using a .m file instead returns proper failure in
that case

This should fix a build failure on freebsd

this way.

The code still modifies state if the timestamp is not found. Not
sure exactly how to avoid that.
asf hacks
if av_read_packet returns AVERROR_IO, we are done. ffmpeg's codecs might or might not handle returning any completed demuxed packets correctly
