lib/drivermmc.{c,h}: Add mmc_have_interface() to see if we've got SCSI

Browse Source 
or ATAPI or whatever.

cdda_interface: Use mmc_have_inteface() we don't have anything for
this except in GNU/Linux. May reduce the unnecessary data_bigendianp()
calls which cause lots of disc reading.

Turn #defines for MMC Profiles into enumeration.
Add enumeration for "core" interface types
