- sleepq_set_timeout acquires callout_lock (via callout_reset()) only
with sleepq chain lock held
- msleep_spin in _callout_stop_safe lock the sleepqueue chain with
callout_lock held
In order to solve this don't use msleep_spin in _callout_stop_safe() but
use directly sleepqueues as inline msleep_spin code. Rearrange the
wakeup path in order to have it consistent too.

This is very similar to sx_init_flags: it initializes the rwlock using
special flags passed as third argument (RW_DUPOK, RW_NOPROFILE,
RW_NOWITNESS, RW_QUIET, RW_RECURSE).
Among these, the most important new feature is probabilly that rwlocks
can be acquired recursively now (for both shared and exclusive paths).
Because of the recursion counter, the ABI is changed.

around an output freezing problem (see the CVS log for details). This
is the same approach that sio takes to solve that problem. However,
ucom has a problem that sio doesn't have.
Consider the case where output is pending, and the device is closed.
ttyclose calls tt_close (which indirects to ucomclose) and then calls
ttyflush which calls tt_stop (which indirects to ucomstop). Since
ucomclose removed all the usb transfer points, sc_oxfer will be NULL
when ucomstop calls ucomstart. This results in a null pointer
dereference.
Since calling ucomstart in ucomstart solves other problems, we need to
work with this calling sequence. The easiest way to do that is to
bail early if sc_oxfer is NULL.
Kazuaki ODA-san came up with this patch, and filed a PR. I had seen
this bug at work and this patch does seem to solve it. He had no idea
why it worked, but knew that either this patch, or backing out ucom.c
1.56 fixed his panic. I just did the legwork of chasing down the code
paths that would cause this, and added a comment. This is obscure
enough to warrant a comment, I think.
