99448ed11d Change the M_NAMEI allocations to use the zone allocator. This change
plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.

013739386f Copy&Paste considered harmful:
Remove all traces of the name_cache from devfs.  It is hardly sensible to
use the namecache for an all-RAM filesystem.

fd7a659f2f Make this compile again after the Lite2 merge.
Call vget/VOP_UNLOCK with the correct number of
arguments.  Call vn_lock where appropriate.
vfs_goneall is now replaced by VOP_REVOKE.

acdbeb6b1c changes to make devfs more 'normal'
also fixes a bug I've been chasing for a LONG TIME,
due to the fact that spec_bwrite is a NOP and I didn't realise it..

old symptom:
mount -t devfs devfs /mnt
mount /mnt/wd0e /mnt/mnt2
umount /mnt2 <process hangs>

there are some pretty large structural differences internal to devfs
but outwards it should look the same.
I have not yet tested extensively but will do so and fix 3 warnings tomorrow.

cleaning up some of the vnode usage..

(I'm sure it still needs more..)
where can one find out what each vfs call expects to be locked
on completion, and how can one find out what each layer expects
to be freed on error.?

ed9a71b7fc symlink support in devfs.
it only barely works so don't get too carried away..
I noticed that teh symlink is length 0..
I guess I'll fix that tomorrow..
it also sometimes panics with "cleaned vnode isn't" but it's not more
broken than it was before.. I really want to go over it with someone
who understands the lifecycle of a vnode better than I do..

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

56c3ab883e find some way of letting a node know where in its parent's directory structure
it was referenced from.. stops a rather annoying panic, but
introduces a rather interesting but "I can live with it" bug
`ln a b ; mv a b; echo ?`
returns a rather than b..
I know why but I need to think of the 'correct' answer. at least this is 'safe'

564643c636 More hacking on devfs..
I can  now do an mv on devices and directories in devfs
This was the hardest part.. link, delete and symlink will follow in
short order.
This code works but has definitly got vnode locking problems
I am electing to get the structure of it working before
spending too much time on the vnode confusion
so it's probably not reliable at the moment..
never-the less it looks good.

ab746f65c1 Suggested by: :) bde of course
added prototypes for every function and
put (void *) as the args to the vop array definitions.

can now compile with:
CWARNFLAGS?=    -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \
                -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes \
                -Winline -Wstrict-prototypes
and only get errors for files external to this module:
namely
./vnode_if.h
../../sys/vnode.h
../../sys/buf.h
../../miscfs/specfs/specdev.h

4777741358 Removed my special-case hack for VOP_LINK and fixed the problem with the
wrong vp's ops vector being used by changing the VOP_LINK's argument order.
The special-case hack doesn't go far enough and breaks the generic
bypass routine used in some non-leaf filesystems. Pointed out by Kirk
McKusick.

if the 'time on a node is 0,..
tell the world it is the same as 'boottime'.
This is becasue 'time' is not set up when we create the nodes,
so we can't set them then.
