sommerfeld c0011ad705 Fix several problems with lockf/fcntl byte range locks: 
- document a data structure invariant in lockf.h
 - add KASSERT() to check the invariant.
 - be more consistent about dequeuing ourselves from the blocked list
after a tsleep().
 - Fix two places where the invariant is violated.
 - correct a few comments here and there
 - If we're still following a lock dependancy chain after maxlockdepth
processes and haven't gotten back to the start, assume that we're in a
cycle anyway and return EDEADLK.

Fix is a superset of an existing fix in FreeBSD, but independantly
derived.

Fixes kern/3860.
