converts miidevs to a .h file, so rename to reflect that.
The usb and pccard versions have also been renamed and will be hooked
into the build system shortly (I've made the conversion in my p4
tree).

for vnodes reached through double indirection (i.e. **vpp). This
is worked-around by special-casing the identifier "vpp" (adding one
level of indirection).
The alternative fix mentioned in the PR had required substantial
changes to this script.
In case there are locking violations that had been hidden without
this patch, they may suddenly show up, now ...
This change does not affect code compiled without DEBUG_VFS_LOCKS.

- Make the VI asserts more orthogonal to the rest of the asserts by using a
new, common vfs_badlock() function and adding a 'str' arg.
- Adjust generated ASSERTS to match the new prototype.
- Adjust explicit ASSERTS to match the new prototype.

- Use the new VI asserts in place of the old mtx_assert checks.
- Add the VI asserts to the automated lock checking in the VOP calls. The
interlock should not be held across vops with a few exceptions.
- Add the vop_(un)lock_{pre,post} functions to assert that interlock is held
when LK_INTERLOCK is set.

in the VOP inlines. This is intended to replace the simple locking
specifications for calls that have more complicated behavior such as rename and
lookup.
The syntax of the new entries is:
#! name pre/post function
If the function is marked 'pre' it is executed prior to calling the VOP and
takes a pointer to a struct vop_{name}_args as it's only parameter.
If the function is marked 'post' it is executed after the VOP call and takes
a pointer to a struct vop_{name}_args as it's first parameter and the integer
return value from the vop as the second paramter.

the kernel while the vnode_if.h header is a bunch of inlines to call the
code that is in the kernel. Generating the .h file on the fly is kinda
bogus because it has to match the one compiled into the kernel.
IMHO we should have kern/vnode_if.c and sys/vnode_if.h committed in the
tree but that's another battle.

incomplete and likely has problem. The code was originally pcmcia,
but I renamed it to pccard and made it compile on FreeBSD -current. I
converted SIMPLEQ to STAILQ as well as a few sc->dev.xname ->
device_printf changes. This is a green port of fairly mature code.
I derived this work from the FreeBSD newconfig project
(http://www.jp.freebsd.org/newconfig). Any problems with it are
likely introduced by me.

lock specifications in kern/vnode_if.src. At present, this do not
distinguish between exclusive and shared locks, and the kernel is so full
of bugs in this area that running with auto-generation of assertions
enabled makes DEBUG_VFS_LOCKS totally useless for anybody that has used it
for anything prior to outputting automated assertions. Due to this, I made
vnode_if.sh only output locking assertions if you have the environment
variable DEBUG_ALL_VFS_LOCKS set to "YES". In order to actually use the
assertions, you need to also add "options DEBUG_VFS_LOCKS" to your kernel
config file.

MII-compliant PHY drivers. Many 10/100 ethernet NICs available today
either use an MII transceiver or have built-in transceivers that can
be programmed using an MII interface. It makes sense then to separate
this support out into common code instead of duplicating it in all
of the NIC drivers. The mii code also handles all of the media
detection, selection and reporting via the ifmedia interface.
This is basically the same code from NetBSD's /sys/dev/mii, except
it's been adapted to FreeBSD's bus architecture. The advantage to this
is that it automatically allows everything to be turned into a
loadable module. There are some common functions for use in drivers
once an miibus has been attached (mii_mediachg(), mii_pollstat(),
mii_tick()) as well as individual PHY drivers. There is also a
generic driver for all PHYs that aren't handled by a specific driver.
It's possible to do this because all 10/100 PHYs implement the same
general register set in addition to their vendor-specific register
sets, so for the most part you can use one driver for pretty much
any PHY. There are a couple of oddball exceptions though, hence
the need to have specific drivers.
There are two layers: the generic "miibus" layer and the PHY driver
layer. The drivers are child devices of "miibus" and the "miibus" is
a child of a given NIC driver. The "miibus" code and the PHY drivers
can actually be compiled and kldoaded as completely separate modules
or compiled together into one module. For the moment I'm using the
latter approach since the code is relatively small.
Currently there are only three PHY drivers here: the generic driver,
the built-in 3Com XL driver and the NS DP83840 driver. I'll be adding
others later as I convert various NIC drivers to use this code.
I realize that I'm cvs adding this stuff instead of importing it
onto a separate vendor branch, but in my opinion the import approach
doesn't really offer any significant advantage: I'm going to be
maintaining this stuff and writing my own PHY drivers one way or
the other.

leaked memory on each unload and were limited to items referenced in
the kernel copy of vnode_if.c. Now a kernel module is free to create
it's own VOP_FOO() routines and the rest of the system will happily
deal with it, including passthrough layers like union/umap/etc.
Have VFS_SET() call a common vfs_modevent() handler rather than
inline duplicating the common code all over the place.
Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a
module) so that the vop_t ** vector is reclaimed.
Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic
rather than a page fault. This could happen if VOP_something() was called
without *any* handlers being present anywhere (including in vfs_default.c).
slot 1 becomes the default vector for the vnodeop table.
