History
Ian Lepore f64342e354 Rework tty_drain() to poll the hardware for completion, and restore 
drain timeout handling to historical freebsd behavior.

The primary reason for these changes is the need to have tty_drain() call
ttydevsw_busy() at some reasonable sub-second rate, to poll hardware that
doesn't signal an interrupt when the transmit shift register becomes empty
(which includes virtually all USB serial hardware).  Such hardware hangs
in a ttyout wait, because it never gets an opportunity to trigger a wakeup
from the sleep in tty_drain() by calling ttydisc_getc() again, after
handing the last of the buffered data to the hardware.

While researching the history of changes to tty_drain() I stumbled across
some email describing the historical BSD behavior of tcdrain() and close()
on serial ports, and the ability of comcontrol(1) to control timeout
behavior.  Using that and some advice from Bruce Evans as a guide, I've
put together these changes to implement the hardware polling and restore
the historical timeout behaviors...

 - tty_drain() now calls ttydevsw_busy() in a loop at 10 Hz to accomodate
   hardware that requires polling for busy state.

 - The "new historical" behavior for draining during close(2) is retained:
   the drain timeout is "1 second without making any progress".  When the
   1-second timeout expires, if the count of bytes remaining in the tty
   layer buffer is smaller than last time, the timeout is extended for
   another second.  Unfortunately, the same logic cannot be extended all
   the way down to the hardware, because the interface to that layer is a
   simple busy/not-busy indication.

 - Due to the previous point, an application that needs a guarantee that
   all data has been transmitted must use TIOCDRAIN/tcdrain(3) before
   calling close(2).

 - The historical behavior of honoring the drainwait setting for TIOCDRAIN
   (used by tcdrain(3)) is restored.

 - The historical kern.drainwait sysctl to control the global default
   drainwait time is restored, but is now named kern.tty_drainwait.

 - The historical default drainwait timeout of 300 seconds is restored.

 - Handling of TIOCGDRAINWAIT and TIOCSDRAINWAIT ioctls is restored
   (this also makes the comcontrol(1) drainwait verb work again).

 - Manpages are updated to document these behaviors.
