This eliminates the large single namecache hash table, and implements
the name cache as a global lru of entires, and a redblack tree in each
vnode. It makes cache_purge actually purge the namecache entries associated
with a vnode when a vnode is recycled (very important for later on actually being
able to resize the vnode pool)
This commit does #if 0 out a bunch of procmap code that was
already broken before this change, but needs to be redone completely.
Tested by many, including in thib's nfs test setup.

second vc is created. However, it was allocated using the geometry of
the second vc to allocate backing store for the first. Be sure to use
the proper values in case geometries differ.

which does pay out, performance wise. one of the conditions to call the
interfaces' if_start routine immediately was "send queue is full".
on a very busy (hammered) machine this will itroduce too much latency
since we spend almost all cpu time in interrupt handlers and softnet,
so the softint actually doing the if_start gets called to seldom and
the queue full check is what triggers the actual transmit.
change the logic to call if's if_start routing immediately when there are
at least 8 packets (or in case if maxlen being smaller than 8, maxlen)
8 chose because it shows best performance in my test setup here.

to free some for use on the rx rings on network cards.
this modifies m_cluncount to advise callers when we're in such a
situation, and makes them responsible for freeing up the cluster
for allocation by MCLGETI later.
fixes an awesome lockup with sis(4) henning has been experiencing.
this is not the best fix, but it is better than the current situation.

Also add a check for the maximum number of sensors like we already have for

right now, we do a pmap_kenter_pa(), we then get the pte (behind pmap's
back) and check for the cache inhibit bit (if needed). If it isn't what
we want (this is the normal case) then we change it ourselves, and do a
manual tlb shootdown (i386 was a bit more stupid about it than amd64,
too).
Instead, make it so that like on some other archs (sparc64 comes to
mind) you can pass in flags in the low bits of the physical address,
pmap then does everything correctly for you.
Discovered this when I had some code doing a lot of bus_space_maps(), it
was incredibly slow, and profilling was dominated by
pmap_tlb_shootwait();
discussed with kettenis@, miod@, toby@ and art@.

- Prevent a double vrele() by setting the vnode pointer to NULL.
- Check if vnode pointers have been set to NULL before trying to
vrele().
- don't double free the component path name buffer.
- Add a workaround for multiple vnode pointers all pointing to the
same vnode and the code doing vrele() on all of them, leading to
botched refcounts. This is a horrible hack, but a real fix is being
worked on.

these cases the xxstop function is a bit more complicated and has a flag of
some sort, but the use of that flag does not matter; DMA is already ceased

MULTIPROCESSOR is defined. This makes splassert incorrect for IPL_NONE
on such kernels.
Make this more similar to amd64, and move the inc and dec of ci_idepth
into the interrupt vectors, and only leave biglock in the locking
functions.
