 1.14  04-May-2017  kamil Use consistently "bufq_private(bufq)" instead of "bufq->bq_private"

No functional change.
 1.13  16-Nov-2016  pgoyette branches: 1.13.6;
Define a new module class for the bufq_strategy modules. These need to
be loaded and intialized before autoconfigure runs, since some devices
(like disks and floppy drives) want to call bufq_alloc().
 1.12  16-Nov-2016  pgoyette Modularize the various bufq strategies
 1.11  19-Jan-2009  yamt branches: 1.11.24; 1.11.42; 1.11.46;
malloc -> kmem_alloc
 1.10  16-Jan-2009  yamt use TAILQ_FOREACH where appropriate, rather than rolling their own.
 1.9  30-Apr-2008  reinoud branches: 1.9.8;
Add a BUFQ_CANCEL() next to BUFQ_PUT() and BUFQ_GET().

BUFQ_CANCEL(queue, element) removes the specified element previously queued
on the queue. It returns NULL if it was not found on the queue and the
element if it was successfully removed.

Run trough tech-kern and changed name from BUFQ_REVOKE() by suggestion of
Jason Thorpe.
 1.8  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.7  01-Feb-2007  cbiere branches: 1.7.40; 1.7.42; 1.7.44;
Avoid unnecessary cast in bufq_disksort_init().
 1.6  11-Dec-2005  christos branches: 1.6.20;
merge ktrace-lwp.
 1.5  29-Oct-2005  yamt MALLOC/FREE -> malloc/free where appropriate.
 1.4  15-Oct-2005  yamt branches: 1.4.2;
- change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
 1.3  25-Nov-2004  yamt branches: 1.3.12;
lookup bufq using link_set rather than a switch statement.
 1.2  28-Oct-2004  yamt move buffer queue related stuffs from buf.h to their own header, bufq.h.
 1.1  14-Oct-2004  yamt branches: 1.1.2;
move i/o schedulers to their own files.
namely, from kern/subr_disk.c to kern/bufq_{fcfs,disksort,readprio,priocscan}.c.
