Add BASIC i386 binary support for the amd64 kernel. This is largely stolen from the ia64/ia32 code (indeed there was a repocopy), but I've redone the MD parts and added and fixed a few essential syscalls. It is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic) and p4. The ia64 code has not implemented signal delivery, so I had to do that. Before you say it, yes, this does need to go in a common place. But we're in a freeze at the moment and I didn't want to risk breaking ia64. I will sort this out after the freeze so that the common code is in a common place. On the AMD64 side, this required adding segment selector context switch support and some other support infrastructure. The %fs/%gs etc code is hairy because loading %gs will clobber the kernel's current MSR_GSBASE setting. The segment selectors are not used by the kernel, so they're only changed at context switch time or when changing modes. This still needs to be optimized. Approved by: re (amd64/* blanket)

Move some declaration of 32-bit signal structures into file freebsd32-signal.h, implement sigtimedwait and sigwaitinfo system calls.

Initial sweep at dividing up the generic 32bit-on-64bit kernel support from the ia32 specific stuff. Some of this still needs to move to the MI freebsd32 area, and some needs to move to the MD area. This is still work-in-progress.
