Actually, QEMU's header-harvesting scripts use uapi/ headers
exclusively, since they are built on "make headers_install".

The extra cleanups that QEMU does on top are to allow compilation of the
headers on non-Linux machines.  They don't really do much more than
changing Linux (linux/types.h) integer types to the C99 (stdint.h)
equivalents.
