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.

Almost identical except for the extra DR_LEN_8 and the different
DR_CONTROL_RESERVED defines.

Mostly the same. Make the few exceptions conditional.

Same file, except for the 64bit PREAMBLE_SIZE define.

Same file, except for the extra 64bit MAP_32BIT define, which does not hurt
for 32 bit compiles.

Same file, except for whitespace and comment formatting.

Scripted unification.

Merge errno.h, resource.h, rtc.h, sections.h, serial.h and sockios.h,
where i386 and x86_64 have no or only trivial comment/include guard
differences.

Build tested on both 32-bit and 64-bit, and booted on 64-bit.

The additional struct member of user_desc can be made conditional for
64 bit compiles.

Aside of the register defines the content can be shared.

Instead of using magic macros for boot_params access, simply use the
boot_params structure.
