to hold all the entries a directory has, we can't signal EOF.

this should speed up NFS writes quite a bit.

encapsulating all such access into wall-defined functions
that makes sure locking is done as needed.
It also cleans up some uses of wall time vs. uptime some
places, but there is sure to be more of these needed as
well, particularily in MD code. Also, many current calls
to microtime() should probably be changed to getmicrotime(),
or to the {,get}microuptime() versions.

Fixes a panic that can occur when trying to link from a local filesystem
to an nfs-mounted one. Problem pointed out by Jim Rees, fix exists
in Net and Free. OK tedu@ csapuntz@

now call the poll backend. With this change we implement greater
poll(2) functionality instead of emulating it via the select backend.
Adapted from NetBSD and including some changes from FreeBSD.

- cache_lookup
move common code from various fs's here
always return with vnode and parent locked
adjust return codes
- PDIRUNLOCK - new flag set if lookup couldn't lock parent vnode
- kernfs and procfs
lock vnode in get_root
don't unlock (again) in kernfs_freevp
fix memory leak in procfs

The inheritace is implemented by setting the default vnodeop to a
bypass op that repeats the operation on the spec/fifo vnodeop vector.
The overhead of one extra indirect function call is worth the cleanup
and improved correctness.
This actually solves a few bugs where some vnode ops were missing from
some vectors (like kqfilter or revoke). (and even more on the ubc
branch).
Inspired by the same thing done in FreeBSD.

by biodone assume splbio (probably just on other filesystems) and some
callbacks from b_iodone assume it too. It's just much safer.

machines or some configurations or in some phase of the moon (we actually
don't know when or why) files disappeared. Since we've not been able to
track down the problem in two weeks intense debugging and we need -current
to be stable, back out everything to a state it had before UBC.
We apologise for the inconvenience.

- get rid of VOP_BALLOCN and VOP_SIZE
- move the generic getpages and putpages into miscfs/genfs
- create a genfs_node which must be added to the top of the private portion
of each vnode for filsystems that want to use genfs_{get,put}pages
- rename genfs_mmap to vop_generic_mmap

code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>.
Tested for the past few weeks by many developers, should be in a pretty stable
state, but will require optimizations and additional cleanups.

While in the area, convert nfs node allocation from malloc to pool and do
some cleanups.
Based on the UBC changes in NetBSD. niklas@ ok.

Change VM/UVM to use buf_replacevnode to change the vnode associated
with a buffer.
Addition v_bioflag for flags written in interrupt handlers
(and read at splbio, though not strictly necessary)
Add vwaitforio and use it instead of a while loop of v_numoutput.
Fix race conditions when manipulation vnode free list

manually twiddling it. This allows the buffer cache to more easily
keep track of dirty buffers and decide when it is appropriate to speed

(from FreeBSD). This avoids the panic described below.
o In nfs_sillyrename(), change a panic if v_type == VDIR to just
a printf (ifdef DIAGNOSTIC) and return EINVAL.
o When building the .nfs file in nfs_sillyrename() don't assume a pid
is only 4 chars long since PID_MAX is 5 chars and use sprintf()
instead of converting the pid to ascii by hand.
Thanks to Theo for assistance and sanity checking.

in txdr_hyper. This should be more portable than casting to an array
of ints and pulling out the two 32-bit words (this produced incorrect
results on alpha for the high word for filesystems < 4gig). As a side
effect, txdr_hyper now takes a u_quad_t as its first arg, not u_quad_t *.

Fix PR/371.
Get rid of locking in NULLFS (should be mostly unnecessary now except for
forced unmounts).
