Clean up ill-advised or unusual header guards

Leading underscores are ill-advised because such identifiers are
reserved. Trailing underscores are merely ugly. Strip both.

Our header guards commonly end in _H. Normalize the exceptions.

Macros should be ALL_CAPS. Normalize the exception.

Done with scripts/clean-header-guards.pl.

include/hw/xen/interface/ and tools/virtiofsd/ left alone, because
these were imported from Xen and libfuse respectively.

bsd-user: pull in target_arch_thread.h update target_arch_elf.h

Update target_arch_elf.h to remove thread_init. Move its contents to
target_arch_thread.h and rename to target_thread_init(). Update
elfload.c to call it. Create thread_os_thread.h to hold the os specific
parts of the thread and threat manipulation routines. Currently, it just
includes target_arch_thread.h. target_arch_thread.h contains the at the
moment unused target_thread_set_upcall which will be used in the future
when creating actual thread (i386 has this stubbed, but other
architectures in the bsd-user tree have real ones). FreeBSD doesn't do
AT_HWCAP, so remove that code. Linux does, and this code came from there.

These changes are all interrelated and could be brokend down, but seem
to represent a reviewable changeset since most of the change is boiler
plate.

Move the architecture specific defines to target_arch_elf.h and delete
them from elfload.c. Only retain ifdefs appropriate for i386 and x86_64.
