Right now, WITNESS just blindly pipes all the output to the
(TOCONS | TOLOG) mask even when called from DDB points.
That breaks several output, where the most notable is textdump output.
Fix this by having configurable callbacks passed to witness_list_locks()
and witness_display_spinlock() for printing out datas.
Reported by: several broken textdump outputs
