few still haven't moved. I've just removed the ones that aren't used.

named link, foo_link or link_foo to lnk, foo_lnk or lnk_foo, fixing
signed / unsigned comparisons, and shoving unused function arguments
under the carpet.
I was hoping WARNS?=6 might reveal more serious problems, and perhaps
the source of the -O2 breakage, but found no smoking gun.
- Eliminate the use of a recursive mutex.
- Mark the driver INTR_MPSAFE.
This work is incomplete and will be refined in a future commit.
- Most notably, _locked() variants of entry points need to be introduced.
- The mii upcall/downcall may still be racy.
- Add a stubbed-out guard against racing rl_detach() for the time being.

Use C99 types. Use ANSI function definitions. Sort prototypes.
Split long lines correctly. Punctuate/wordsmith comments.
Use device_printf()/if_printf() where possible.

- Eliminate the use of a recursive mutex.
- Mark the driver as INTR_MPSAFE.
- Split the default media choice code out into xl_choose_media() to
avoid making poor assumptions about the state of the lock during attach.
- The miibus upcall/downcall paths may still be racy.
Change to commented-out locking assertions there for now.
- Tested with nfsclient, routed, ssh, ntp, dhclient and quagga bgpd.
- This needs SMP test coverage. I do not have such resources.

Speed up the syncer when shutting down by sleeping for a shorter
period of time instead of cranking up rushjob and using the
normal one second sleep.
Skip empty worklist slots when shutting down to avoid lengthy
intervals of inactivity.
Give I/O more time to complete between steps by not speeding the
syncer quite as much.
Terminate the syncer after one full pass through the worklist
plus one second with the worklist containing nothing but syncer
vnodes.
Print an indication of shutdown progress to the console.
Add a sysctl, vfs.worklist_len, to allow the size of the syncer worklist
to be monitored.
- Use device_printf() during device probe/attach.
- Move if_xname initialization to before xl_reset() is called.
- Use if_printf() at all other times after struct ifnet has been
initialized.
