- break anon related functions out of uvm_amap.c and put them in their own

an anon init function

fields (add macros to amap api as needed)

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.

Use the pool allocator w/ the "nointr" pool page allocator for uvm_aobj

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'.
