Log Message:
Multiboot2 kernel support for i386

That implementation works either with BIOS or UEFI bootstrap

This requires the following kernel changes:

Add UEFI boot services and I/O method protoypes
src/sys/arch/x86/include/efi.h 1.8 - 1.9

Fix EFI system table mapping in virtual space
src/sys/arch/x86/x86/efi.c 1.19 - 1.20

Make sure no bioscall is issued when booting off UEFI system
src/sys/arch/i386/i386/machdep.c 1.821 - 1.822
src/sys/arch/i386/pci/piixpcib.c 1.22 - 1.23

And the following bootstrap changes:

Add kernel symbols for multiboot1
src/sys/arch/i386/stand/lib/exec_multiboot1.c 1.2 - 1.3
src/sys/arch/i386/stand/lib/libi386.h 1.45 - 1.47

Fix kernel symbols for multiboot2
src/sys/arch/i386/stand/lib/exec_multiboot2.c 1.2 - 1.3
