- Rename vxfoo() functions to vx_foo() to improve readability and
consistency with other drivers.
- Prefix most the softc members with 'vx_' (the other members already had
the prefix).
- Switch to using callout_init_mtx() and callout_*() rather than
timeout() and untimeout().
- Add some missing calls to if_free() in some failure cases in vx_attach().
- Use if_printf() and remove the unit number from the softc.
- Remove uses of the 'register' keyword and spls.
- Add locked variants of vx_init() and vx_start().
- Add a mutex to the softc and lock it in various appropriate places.
- Setup the interrupt handler last during attach.

It allows to specify options for NFS root file system.
Currently supported options are: soft, intr, conn, lockd.
I'm adding this functionality mostly for 'lockd' option, which is only
honored when performing the initial mount and will be silently ignored
if used while updating the mount options.
This will allow to use flock(2) without the need of using varmfs or
rpc.lockd and friends.
Example of use:
boot.nfsroot.options="intr,lockd"

- http is a lightweight, multithreaded HTTP query tool, which performs
a timed measurement of the rate at which it can download files using
single-fetch HTTP/1.0. Other than specifying the IP and a URL path,
it requires zero configuration.
- httpd is a lightweight, multithreaded HTTP server tool, which exports
a single file of choice to the HTTP client, and responds with it no
matter what the request. Other than specifying the file to export,
it requires zero configuration.
The goal of these tools is to measure the network costs associated with
HTTP serving, rather than file system, HTTP protocol parsing, error
handling, etc, and as such, parts relating to less interesting components
of HTTP testing are intentionally omitted. Both are linked against
libpthread by default.

Really, really nasty bug and a very nice catch of mine.

- Don't keep the SPDIF state in the driver private struct since it
can be overriden by hand with pciconf(8), query it when needed instead.
Regarding the locking I let Ariff explain it himself:
---snip---
About the locking, that is what I'm intended to do since the beginning.
The reason I'm not putting that along since my first patchset was
because several people especially from amd46 camp reported that it cause
lots of LORs, which is weird considering that I've never encounter such
in a pretty much strict locking environment (i386). However, since our
previous discussion with Pyun YongHyeon about strict locking, I've
decided to bring it back for all the affected drivers, not just for
es137x. It turns out that the root of the problem was within dsp.c
during device open, which has been fixed since dsp.c revision 1.84.

- Remove references to cpu_critical_*() as they no longer exist.
- Explain that any preemptions that occur during a critical section are
deferred until the current thread exits the section.
- Remove a bogus example usage of a critical section.

for mutual exclusion:
A brief description of the problem:
1) Proc A picks up non-blocking lock on file X
2) Proc B attempts to pickup lock, fails then waits
3) Proc C attempts to pickup lock, fails then waits
4) Proc A releases lock
5) Proc B acquires lock, release it to pickup a non-blocking version
6) Proc C acquires lock, release it to pickup a non-blocking version
7) Both process B and C race each other to pickup lock again
This occurs mainly because the processes do not keep the lock after they have
been waiting on it. They drop it, attempt to re-acquire it. (They use the wait
to notify when the lock has become available then race to pick it up). This
results in additional CPU utilization during the race, and can also result
in processes picking locks up out of order.
This change attempts to correct this problem by eliminating the test/acquire
race and having the operating system handle it.
