Update gPXE to version 0.9.6+ 277b84c6e7d49f3cf01c855007f591de8c7cb75f
Update gPXE to version 0.9.6+, from commit 277b84c6e7d49f3cf01c855007f591de8c7cb75f in the main gPXE repository. The only differences is src/config/general.h which has a few protocols added, and src/arch/i386/prefix/boot1a.S which was called boot1a.s in the upstream repository.
