configure: add header_check_broken, use for cdio

Make the sys/cdio.h header test work by explictly including
sys/types.h before.
Broken headers are a Solaris and BSD tradition, hoping
for them to get their act together is hopeless, so we
work around it (for now at least).

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@31855 b3059339-0415-0410-9bf9-f77b7e298cf2

Add a special header_check_broken to be used for broken
system headers taht do not include all dependencies
and use it for the Solaris uscsi header.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@31856 b3059339-0415-0410-9bf9-f77b7e298cf2

Use header_check_broken to simplify cdio.h check.
