Catch up with the usage of struct vmspace::vm_refcnt

Use the dedicated reference counting routines.

Change the type of struct vmspace::vm_refcnt and struct vm_map::ref_count
to volatile.

Remove the unnecessary vm->vm_map.misc_lock locking in process_domem().

- uvmspace_exec(), uvmspace_free(): if pmap_remove_all() returns true the
  pmap is emptied.  Pass UVM_FLAG_VAONLY when clearing out the map and avoid
  needless extra work to tear down each mapping individually.

- uvm_map_lookup_entry(): remove the code to do a linear scan of map entries
  for small maps, in preference to using the RB tree.  It's questionable,
  and I think the code is almost never triggered because the average number
  of map entries has probably exceeded the hard-coded threshold for quite
  some time.

- vm_map_entry: get it aligned on a cacheline boundary, and cluster fields
  used during rbtree lookup at the beginning.

UVM locking changes, proposed on tech-kern:

- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart.  v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap.  Others to follow later.

- uvm_unmap_remove(): need to call pmap_update() with the object still
  locked, otherwise the page could gain a new identity and still be visible
  via a stale mapping.

- Adjust reference counts with atomics.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Introduce "top down" memory management for mmap()ed allocations.  This
means that the dynamic linker gets mapped in at the top of available
user virtual memory (typically just below the stack), shared libraries
get mapped downwards from that point, and calls to mmap() that don't
specify a preferred address will get mapped in below those.

This means that the heap and the mmap()ed allocations will grow
towards each other, allowing one or the other to grow larger than
before.  Previously, the heap was limited to MAXDSIZ by the placement
of the dynamic linker (and the process's rlimits) and the space
available to mmap was hobbled by this reservation.

This is currently only enabled via an *option* for the i386 platform
(though other platforms are expected to follow).  Add "options
USE_TOPDOWN_VM" to your kernel config file, rerun config, and rebuild
your kernel to take advantage of this.

Note that the pmap_prefer() interface has not yet been modified to
play nicely with this, so those platforms require a bit more work
(most notably the sparc) before they can use this new memory
arrangement.

This change also introduces a VM_DEFAULT_ADDRESS() macro that picks
the appropriate default address based on the size of the allocation or
the size of the process's text segment accordingly.  Several drivers
and the SYSV SHM address assignment were changed to use this instead
of each one picking their own "default".

creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.
