fada20b989 Add devclass_get_drivers(9) which provides an array of pointers to driver 
instances in a given devclass.  This is useful for systems that want to
call code in driver static methods, similar to device_identify().

f3011a7c10 Clarify that the end argument meaning for rman_reserve_resource_bound 
is the highest acceptable value for the ending of the resource being
allocated.  One could also believe that it is the highest starting
value of the resource.  The code definitely expects the former, but I
could find no documentation of this apart from TFSC.

bc9d299133 Change the definition of struct if_data's member ifi_epoch from wall 
clock time to uptime because wall clock time may go backwards.

This is a change in the API which will impact SNMP agents who are using
ifi_epoch to set RFC2233's ifCounterDiscontinuityTime.  None are know to
exist today.  This will not impact applications that are using the
<index, epoch> tuple to verify interface uniqueness except that it
eliminates a race which could lead to a false assumption of uniqueness.

Because this is a behavior change, bump __FreeBSD_version.

6009275136 Don't say that mtx_lock() will "sleep" if another kernel thread is 
holding the mutex, say it will "block".  Later in this manual page
we say that sleeping while holding a mutex isn't allowed, and this

98c926b20f Add a mechanism for associating a mutex with a callout when the 
callout is first initialised, using a new function callout_init_mtx().
The callout system will acquire this mutex before calling the callout
function and release it on return.

In addition, the callout system uses the mutex to avoid most of the
complications and race conditions inherent in asynchronous timer
facilities, so mutex-protected callouts have much simpler semantics.
As long as the mutex is held when invoking callout_stop() or
callout_reset(), then these functions will guarantee that the callout
will be stopped, even if softclock() had already begun to process
the callout.

Existing Giant-locked callouts will automatically pick up the new
race-free semantics. This should close a number of race conditions
in the USB code and probably other areas of the kernel too.

There should be no change in behaviour for "MP-safe" callouts; these
still need to use the techniques mentioned in timeout(9) to avoid
race conditions.
