rump/x86: Need x86/cpufunc.h for declaration of wbinvd.

update from HEAD

Sync with HEAD

Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories.  Avoids having
to add a CPPFLAGS (or several) to pretty much every component
Makefile.

Leave compat headers around in the old locations.

The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

Sync with HEAD

Apparently not all ports define struct clockframe in cpu.h, so we cannot
provide our definition that way.  Instead, generate the struct clockframe
passed to hardclock() in MD code.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Allow compile-time optimizations to curlwp.  This can have a pretty
staggering impact on performance.  When running sendto() in a loop,
the improvement is 200k more calls per second with an inlined __thread
curlwp as opposed to the default.  In other words, it shaves off hundreds
of CPU cycles per call (~20%).  Even just eliminating the x86_curlwp()
call in favor of an inline gives an improvement of 60k calls per second.

Rototill a bit, and attempt to disguise it as non-gratuitous.

Add arch/generic and move non-x86 files from rumpkern/ there.  Also,
move files from arch/i386 to arch/x86, and make both i386 and x86_64
use those.

This clarifies the situation with what is MD vs. MI code.

renames:
  rumpcpu_generic,kobj_stubs,pmap_stubs => arch/generic/rump_generic_$x
  arch/i386/* => arch/x86/rump_x86_$x

(for those who forget, x86 requires MD code because rump kernels
use the same ABI as kernel modules)
