Subject: [PATCH] [ISOHYBRID] Patch all our ISOs (bootcd, bootcdregtest,
 livecd, hybridcd) with isohybrid in order to make them bootable from HDDs or
 any kind of USB drives. The added MBR at the beginning of each ISO doesn't
 cause any harm for normal CD booting anymore after my patch in r74460. There
 is also no need for the dedicated isohybrid targets anymore.

Our ISOMBR master boot record now successfully loads our ISOBOOT boot sector. ISOBOOT loads FreeLdr and indicates that we're booting from HDD, so that FreeLdr can successfully load the kernel.
We then bugcheck in the kernel with either 0x0000007B (INACCESSIBLE_BOOT_DEVICE) using bootcd or 0x0000006B (PROCESS1_INITIALIZATION_FAILED) using livecd.
Testcase is:
  qemu-system-i386 -m 512 -hda bootcd_or_livecd.iso

Needs more investigation, but these are separate bugs and I consider CORE-12648 fixed.
