[syslinux] SYSLINUX 3.70-pre8

[H. Peter Anvin]

I have just pushed out SYSLINUX 3.70-pre8.  The two main differences is 
that I have updated the gPXE source base, and added a sanboot module 
(sanboot.c32).  sanboot.c32 *should* be capable of initiating an iSCSI 
or AoE boot, but I haven't actually tested it.

The other main difference is that gPXE now advertises HTTP/1.0 instead 
of HTTP/1.1, since the code was not actually HTTP/1.1 compliant; 
resulting in corrupted transfers.
