[Etherboot-developers] [COMMIT] Multicast & more.

[<ebi...@ln...>]

I have committed my first first round of changes to be a productive
bootloader for LinuxBIOS, into the etherboot-5.1 tree.  I believe I
have only included the good bits but I have only tested the merge with
my tree to see if it compiles.  Holler if it breaks, something for you/

Included.
- Added multicast support
- Added a pc floppy driver
- reorganized osloader so the code is more local for the various file
formats
- rewrote the network stack filter functions so they are supplied explicitly the protocols
- made ipchksum handle odd lengths
- added an experimental multicast download protocol
- moved pxe support into it's own file.  Too many nasty ifdefs in the code otherwise
