* Expand the example descriptions, fix mdoc-bugs in "(-a and -t vnode are implied)" and reuse it near the cd9660 example. * Spell 'backing store' as two words.

Update the description of -l to reflect reality. After mdconfig.c 1.25, -l without -u only lists the names, so specifying -u does more than just limit the output to one device.

Fix a long-standing deadlock issue with vnode backed md(4) devices:
On vnode backed md(4) devices over a certain, currently undetermined size relative to the buffer cache our "lemming-syncer" can provoke a buffer starvation which puts the md thread to sleep on wdrain.
This generally tends to grind the entire system to a stop because the event that is supposed to wake up the thread will not happen until a fair bit of the piled up I/O requests in the system finish, and since a lot of those are on a md(4) vnode backed device which is currently waiting on wdrain until a fair amount of the piled up ... you get the picture.
The cure is to issue all VOP_WRITES on the vnode backing the device with IO_SYNC.
In addition to more closely emulating a real disk device with a non-lying write-cache, this makes the writes exempt from rate-limited (there to avoid starving the buffer cache) and consequently prevents the deadlock.
Unfortunately performance takes a hit.
Add "async" option to give people who know what they are doing the old behaviour.
