Add ATTR_NEVER_INLINE attribute. Add EEPROM byte read/write proxy functions to the Mass Storage bootloader to prevent link errors due to linker relaxations.

Update Mass Storage bootloader for Linux compatibility, and to reduce the compiled bootloader size. Linux appears to replace files with a cluster offset on the disk rather than re-using the same disk clusters (unlike Windows) so the file offset needs to be tracked and compensated for.

Add Long File Name (VFAT) entry to the Mass Storage class bootloader, so that systems such as Linux that load a VFAT filesystem driver instead of the legacy MSDOS filesystem do not corrupt the volume by trying to write a LFN entry.

Significantly reduce the size of the Mass Storage class bootloader, by removing dependencies on large LUFA internal functions.

Update Mass Storage bootloader so that it can support devices with only 4KB bootloader sections by creating a special AUX section before the real bootloader section to store part of the bootloader code.

Fix off-by-one error in the Mass Storage bootloader file size, add missing Volume Label directory entry. Remove incorrect reference to "printer" in the bootloader documentation.

Move out the Mass Storage class bootloader to the main Bootloader directory now that it is functional.

Add documentation to the incomplete Mass Storage class bootloader, update the virtual FAT file entry so that the bootloader section is omitted (not user readable/writable). Fix some minor documentation errors in the Printer class bootloader.
