In fact, the request sense timer was overflowing prior to this change making
it much shorter than intended.

- Remove div_disconnect() method, since it shouldn't be called now.
- Remove div_abort() method. It was never called directly, since protocol
doesn't have listen queue. It was called only from div_disconnect(),
which is removed now.

add the working directory pathname to the log message if any of
such arguments isn't absolute. This has advantage over the old
way of logging that an admin can see what users are actually trying
to do, and where. The old code was also not too robust when it
came to a chrooted session and an absolute pathname.

setting the B_REMFREE flag in the buf. This is done to prevent lock order
reversals with code that must call bremfree() with a local lock held.
This also reduces overhead by removing two lock operations per buf for
fsync() and similar.
- Check for the B_REMFREE flag in brelse() and bqrelse() after the bqlock
has been acquired so that we may remove ourself from the free-list.
- Provide a bremfreef() function to immediately remove a buf from a
free-list for use only by NFS. This is done because the nfsclient code
overloads the b_freelist queue for its own async. io queue.
- Simplify the numfreebuffers accounting by removing a switch statement
that executed the same code in every possible case.
- getnewbuf() can encounter locked bufs on free-lists once Giant is removed.
Remove a panic associated with this condition and delay asserts that
inspect the buf until after it is locked.

This same bug was fixed in the 4.x stream a few years ago, but the fix
was never propogated to -current.
This fix is slightly different than in -stable:
o Use offsetof() instead of a hard coded constant so as the make
the code more self-explainatory.
o Round odd long inquiry lengths up so as to avoid tickling ignore
wide residue bugs in broken parallel SCSI devices running with a
wide transfer negotiation.
