895e09b8c5 Sprinkle some more locking, especially to the vm. Due to some 
additional fixes, it's now possible to run file systems with
spinlocks actually enabled.  The genfs_putpages() locking is still
working only due to greater powers, but I'll eventually get around to
fixing it.

08ac8063af Fix some comments: thinking of it more closely, it is actually safe 
to release the sleep interlock before calling cv_wait() because we
are protected by the list mutex which prevents a wakeup race.

18ae49a27c Make the strategy routine get the results through biowait() and 
the "disk driver" (rumpuser) call biodone() to indicate the completion
of I/O.  Support for B_ASYNC is coming at some point, but I need
more locking support in the emulated vm for that.

87f9ee4c42 Make it possible to run rumps multithreaded. This brings real 
locking and makes it possible to run file systems which create
threads.  It also makes rump file system behaviour better match
file system behaviour in the kernel.

6640f4d32a It's non-trivial to say that "no, we don't have cpu counter on this 
arch (rump)", so emulate it.  But this is suboptimal.  The crux of
the problem seems to be that types.h contains both information on
the machine architecture (which we want) as well as other defines
such as __HAVE_CPU_COUNTER (which we don't want).

50591a9595 "flags * (M_CANFAIL | M_NOWAIT)" is probably not correct. Use & instead.

3856acafe2 Update the file system copy-on-write handler. 
- Instead of hooking the handler on the specdev of a mounted file system
  hook directly on the `struct mount'.

- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'.  Use
  `mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.

- Replace the hand-made reader/writer lock with a krwlock.

- Keep `vn_cow_*' functions and mark as obsolete.

- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

b795ecbe79 fsync() device fd if doing a non-B_ASYNC write. This makes the 
file system safe, but less performant as the kernel, as it syncs
*all* outstanding dirty buffers.  However, we don't have much choice
in userspace currently.
