vnode: do not manipulate vnode lock directly

use VOP_LOCK / VOP_UNLOCK wrappers.

VOP_LOCK() is prefered over vn_lock() here in order to keep equivalent code.

Drop unnecessary `p' parameter from vget(9).

Remove the lockmgr() API. It is only used by filesystems, where it is a
trivial change to use rrw locks instead. All it needs is LK_* defines
for the RW_* flags.

tested by naddy and sthen on package building infrastructure
input and ok jmc mpi tedu

Remove some includes include-what-you-use claims don't
have any direct symbols used. Tested for indirect use by compiling
amd64/i386/sparc64 kernels.

apply siphash to the key selection for the ufs inode hash.

fix potential race where an allocated inode could fail to get added,
noticed by pedro@ in bitrig.

UFS does't do inode numbers >2^32, so use a smaller type internally,
only using ino_t in the VFS layer APIs: vget, readdir, getattr.

Replace XXXLOCKING comments by me (replacing simple_locks that are the
same thing) with mutexes.

From Gabriel Kihlman (gk AT stacken DOT kth DOT se); thanks!

ok art@ ages ago.

simple_lock -> XXXLOCKING for ufh ihash.

I'm actually 99% sure that these locks are right and could be almost
trivially converted to an IPL_NONE mutex protecting the hashtable. Any
takers?

Remove the v_interlock simplelock from the vnode structure.
Zap all calls to simple_lock/unlock() on it (those calls are
#defined away though). Remove the LK_INTERLOCK from the calls
to vn_lock() and cleanup the filesystems wich implement VOP_LOCK().
(by remvoing the v_interlock from there calls to lockmgr()).

ok pedro@, art@, tedu@

Remove unnecessary lockmgr() archaism that was costing too much in terms
of panics and bugfixes. Access curproc directly, do not expect a process
pointer as an argument. Should fix many "process context required" bugs.
Incentive and okay millert@, okay marc@. Various testing, thanks.

Use ANSI function declarations and deregister, no binary change.
Diff from Rui Reis <rui@rui.cx>, thanks.

Use list and queue macros where applicable to make the code easier to read;
no change in compiler assembly output.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Silently allow removal of inodes that aren't on the hash queues
