Replaced Mac OS X's C++ cdrom code with almost-direct translation to C. Sam
requested this effort on the mailing list, apparently because of binary
compatibility issues between 10.4 and earlier systems (or gcc4 and earlier
compilers?).
Works fine with SDL12/test/testcdrom.c, with this command line:
./testcdrom -status -list -play -sleep 5000 -pause -sleep 3000 -resume \
-sleep 5000 -stop -sleep 3000 -play -sleep 3000 -stop \
-sleep 3000 -eject
Unix Makefiles work, XCode project still need updating for new filenames.
