44f5fc2839 cleanup/reorg:
- break anon related functions out of uvm_amap.c and put them in their own
  file (uvm_anon.c).  includes break up uvm_anon_init into an amap and an
  an anon init function
- ensure that only functions within the amap module access amap structure
  fields (add macros to amap api as needed)

0c2374e586 fix a precedence problem in uvm_mk_pcluster() which prevented
clustering of vnode pageouts.  this probably makes no difference
since most apps don't write via the pagecache anyway... yet.

e21b4568e2 When a reference is made to a hole in a swap file, panic. The optimal
thing would be to allocate the block, but I don't know how to do this.
The panic is preferable to the random memory corruption the old code
was causing.

025ae6bd64 remove unused share map code from UVM:

2d4c15ebc9 remove unused share map code from UVM:
- replace map checks with submap checks
 - get rid of unused 'mainonly' arg in uvm_unmap/uvm_unmap_remove, simplify
	code.   update all calls to reflect this.
 - don't worry about unmapping or changing the protection of shared share
	map mappings (is_main_map no longer used).
 - remove unused uvm_map_sharemapcopy() function from fork code.

1b59a238c4 remove unused share map code from UVM:

 - adjust locking and lookup functions in uvm_fault_i.h to reflect the above
 - replace ufi.rvaddr with ufi.orig_rvaddr in uvm_fault.c since rvaddr is
	no longer needed.
 - no need to worry about share map translations in uvm_fault().  simplify.

8219f068e2 Declare silent success on madvise(). As an advisory call, it is harmless
to pretend success even though it's not supported, and some emulations

5dd4b45577 Don't use the nointr pool page allocator for the uao_swhash_elt pool. We
need to ensure that these come from a non-pageable kernel map, otherwise
we can run into a deadlock condition (as noticed by Chuck Silvers).

5a4981d9b8 Use the pool allocator w/ the "nointr" pool page allocator for uvm_aobj
and uao_swhash_elt structures.  Also, fix a bug in uao_set_swlot() where
if setting the swslot to 0 (freeing swap resources), and no swslot was
currently allocated, a new entry would be allocated anyhow (revealed during
pool'ification).

b5f69ff667 add a `char se_path[PATH_MAX]' member to struct swapent, that
the pathname of the swap device is saved into.  add a char *swd_path
member to struct swapdev, that contains a copy of the pathname
(using malloc(9)).  rename swapctl(2)'s SWAP_STATS to SWAP_OSTATS,
and add a new SWAP_STATS command (number).  make swapctl(SWAP_STATS,
...) [new version] copy the path out.  if COMPAT_13, also include
support for SWAP_OSTATS.  also fix a minor bug in swapctl(2).

the point of this is that swapfiles are now shown in `swapctl -l'.

9b25897ec0 minor consistency nit: the page index into an anon object is always
assigned to from integer types, and it is compared to integers. So
let it be an integer instead of vsize_t.
