- Initialize lock structure in vncache_alloc
- Return locked vnodes from vncache_alloc
- Setup vnode op vectors to use default lock, unlock, and islocked
- Implement simple locking scheme required for lookup
to a malloc'd buffer in dmpindir() and dirindir(). These functions
recursively call themselves to handle deeper levels of indirect
blocks, so a single static buffer was not suitable.

Approach suggested by: bde
and -Wformat warnings:
o Include timeconv.h for the time conversion functions.
o Remove unused variables.
o Correct a few cases where %d was used when printing longs.
mappings from the page tables, which were mapped with PG_G! We could
reuse the page table entry for another mapping (pmap_mapdev) but it
would never have cleared any remaining PG_G TLB entries.
pmap_swapin_proc/pmap_swapout_proc functions from the MD pmap code
and use a single equivalent MI version. There are other cleanups
needed still.
While here, use the UMA zone hooks to keep a cache of preinitialized
proc structures handy, just like the thread system does. This eliminates
one dependency on 'struct proc' being persistent even after being freed.
There are some comments about things that can be factored out into
ctor/dtor functions if it is worth it. For now they are mostly just
doing statistics to get a feel of how it is working.
sense. Since portmap/rpcbind is in /usr/sbin it doesn't make any sense for
nfsd and mountd to be in /sbin.
For the record, NetBSD has them in /usr/sbin while OpenBSD has them in /sbin

the new content size fits into the sbuf, instead of assuming
that allocating twice the old size is enough.
- Use memmove(3) rather than strcpy(3) to copy overlapping
strings.

Tell vop_strategy_pre() to use this instead.
- Ignore B_CLUSTER bufs. Their components are locked but they don't really
exist so they don't have to be. This isn't ideal but it is safe.

- If the handle is a vnode in vm_mmap() assert that it is locked.
- Wiggle Giant around a little to account for the extra vnode operation.
