Make asm-x86/bootparam.h includable from userspace.
To actually write a bootloader (or, say, the lguest launcher)
currently requires duplication of these structures. Making them
includable from userspace is much nicer.
We merge the common userspace-required definitions of e820_32/64.h
into e820.h for export.
