Fixes for bugs not shared with ffs:
- don't mount unclean filesystems rw unless forced to.
- accept EXT2_ERROR_FS (treat it like !EXT2_VALID_FS). We still don't set
this or honour the maximal mount count.
- don't attempt to print the name of the mount point when mounting an
unclean file system, since the name of the previous mount point is
unknown and the name of the current mount point is still "".
Fixes for bugs shared with ffs until recently:
- don't set the clean flag on unmount of an initially-unclean filesystem
that was (forcibly) mounted rw.
- set the clean flag on rw -> ro update of a mounted initially-clean
filesystem.
- fixed some style bugs (mostly long lines).
The fixes are slightly simpler than for ffs, because the relevant on-disk
state is not a simple boolean variable, and the superblock has a core-only
extension.

This uses the fs_flags field and FS_UNCLEAN state bit which were
introduced in the softdep changes. NetBSD uses extra state bits in
fs_clean.

- there were too many global variables (there still are :-).
- the data section was bloated by explicit initializations of static
variables to 0 (only fixed the recently changed ones).
- WRAPHIST() had silly parentheses around foo->bar.
- the comment about inline functions was stale.
- the comment about Userconfig presumes too much about the boot environment.
- `i' was reused confusingly in scioctl().
- the declaration of `butmap' used a deprecated K&R misfeature.
- the initializeation of `butmap' had an unnecessary line break.
- `unsigned char' was not consistently (mis)spelled as u_char.
- English was poor in a comment in videoio.c.

Also apply a patch to force the transmit start routine to check the
transmitter to make sure it isn't wedged if the outbound tx queue appears
full. This seems to cure some problems with 'watchdog timeout' errors
cropping up in some cases. I tried to do this before by checking for the
IFF_OACTIVE flag on entry to xl_start(), but if the IFF_OACTIVE flag is
set, ether_output() won't even call xl_start(). It should work now.
Lastly, increase the size of the TX queue from 10 descriptors to 16 to
hopefully make it less likely that the TX queue will fill up.

PHYs in tl_attach(). This is mainly to suck away any possible stray
interrupts.
This prevents an intermittent problem on some systems where the adapter
probes correctly but yields a device timeout (and possible subsequent adapter
check) when configured. When I originally tested the driver, I ifconfig'ed
the interface after the system had already been booted and didn't notice
any problems, but when configuring the interface immediately at startup,
it would occasionally timeout and hang, until an adapter check interrupt
came along and reset things again. I'm not exactly sure if this is a
general problem of just something peculiar to this hardware (there are
three devices, including the tlan, all on IRQ 11) but the extra reset
shouldn't hurt anything. (It works fine with my 100Mbps Olicom adapter too.)

Two minor changes are also included,
1. Remove gratuitious checks for error return from vn_lock with LK_RETRY set,
vn_lock should always succeed in these cases.
2. Back out change rev. 1.36->1.37, which unnecessarily makes async mount
a little more unstable. It also keeps us in sync with other BSDs.
