The page and section fault handling paths are essentially identical, so
...
combine them. This also fixes a performance issue, in that we always
faulted pages twice in order to write them.

The ARM has the same copy-on-write bug as the i386 -- the write enable bit in
...
PTEs is ignored when in kernel mode. Hack around this just like we do on the
i386, by adding a prepass to copyout() to check for write permission on the
destination pages.

More cleanup...
...
* Don't bother pulling PT_M and PT_H bits from pv_flags; they can't ever be
set there!
* Actually make pmap_clear_reference() do something useful.
* Also set the referenced bit (PT_H) when emulating a write fault.

Repeat after me:
...
If we're doing modified bit emulation, we must revoke write permission in
pmap_clear_modify(). This is non-negotiable. I will revoke write permission
in pmap_clear_modify(), or suffer the wrath of a thousand bricks.
