        src/sys/dev/dm: device-mapper.c dm.h dm_target.c dm_target_error.c
            dm_target_linear.c dm_target_mirror.c dm_target_snapshot.c
            dm_target_stripe.c dm_target_zero.c

Log Message:
Add support for DIOCCACHESYNC ioctl for dm devices. Add new sync function
pointer to dm_target_t because that is the only part of dm which know real
block device. disk_ioctl_switch parses whole device table and for every
entry it calls particular sync routine which propagates DIOCCACHESYNC
to real disk.

While I was here implement some KNF fixes and remove unneeded symbols from
dm.h.

Problem reported on port-xen@ by Hugo Silva.
