Don't grab Giant in the upper syscall/wrapper code
NET_LOCK_GIANT in the socket code (sockets/fifos).
mtx_lock(&Giant) in the vnode code.
Devfs grabs Giant if the driver is marked as needing Giant.
FILEDESC_LOCK_FAST will just grab the interlocking mutex and hold
it. This should be used for simple modifications of a field.
FILEDESC_LOCK holds a (homegrown) sleepable lock which should be used
where sleeping is required.
The homegrown lock will probably be replaced with a generic type of lock
once we have found out how that should look.

- Allow the upload directory to be optional. If the upload directory
field is cleared to the empty string then no directory will be created.
- Don't create a bin/ subdirectory in ftp's home dir containing ls(1) and
date(1) as ftpd(8) no longer requires it.
- Create a pwd.db file in etc/ instead of a passwd file.
- Ignore NIS compat entries in /etc/group and /etc/master.passwd when
building the anonymous files.

after boot so that PCI is initialized and we can probe for the problem
chipsets. Note that while probed but unusable states are disabled, they
aren't freed yet. In the future, it may make sense to detach them.

a storm is detected, enter "storming" mode which throttles the interrupt
source such that the handlers are run once every clock tick. Previously
we allowed a full set of storm_threshold interations through the handler
before going back to sleep. Also, this currently will intentionally exit
storming mode once a second to see if the storm has passed.

backed out commits were trying to address: when cancelling the timeout
callout, also cancel the abort_task event, since it is possible that
the timeout has already fired and set up an abort_task.
also fix up handling and proding of the tx, _OACTIVE is now handled
better...
