[BOOTDATA]: Diverse improvements for mkisofs support and ISO image configuration:
- Make our build system create the required empty directory for mkisofs, instead. (It's not the purpose of the SVN to hold special files/directories just to make host tools happy; instead it's the job of the buld system to create them.)
- Place the boot files (catalog & co.) preferably at the beginning of the ISO image (it makes ISO image analysis easier, and is back-compatible with cdmake & oscdimg & windows ISOs): use the build system to generate the mkisofs sorting file. See the CMakeLists.txt for more details.
- Set in one place the ISO manufacturer & volume name strings so that it makes easier to bulk-change them (and makes features like CORE-12233 a bit easier to maintain).
- The EFI image must be set up with no emulation mode! (See section "12.3.2.1 ISO-9660 and El Torito" of the UEFI spec v2.4 errata B, for example).
[MKISOFS]: Add some useful offline documentation.
