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.

Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
...
bcopy(x, y, z) -> memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
bcmp(x, y, z) -> memcmp(x, y, z)
bzero(x, y) -> memset(x, 0, y)

fix sizeofs so they comply with the KNF style guide. yes, it is pedantic.

some prototype cleanup, eliminate/replace bogus types (e.g. quad and

u_quad) -> use better types (e.g. quad_t & u_quad_t in inodes),
some cleanup.
