mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

Add the missing option LK_NOWITNESS for vn_lock / VOP_LOCK operations.

Modify VOP_ISLOCKED() and lockstatus() prototypes in order to reflect
'thread' argument axing.

Update VOP_LOCK() and VOP_UNLOCK() prototypes.
Leave 'td' argument description as it is used by VOP_ISLOCKED(). It will
be axed in further commit.

Removed a contraction.

Update vn_lock() prototype accordingly with the 'thread' argument removal.

Trimm out now unused option LK_EXCLUPGRADE from the lockmgr namespace.
This option just adds complexity and the new implementation no longer
will support it, so axing it now that it is unused is probabilly the
better idea.

FreeBSD version is bumped in order to reflect the KPI breakage introduced
by this patch.

In the ports tree, kris found that only old OSKit code uses it, but as
it is thought to work only on 2.x kernels serie, version bumping will
solve any problem.

Garbage-collect following nomore existing options:
- LK_REENABLE
- LK_NOPAUSE
- LK_NOOBJ

Use 'manual page' instead of 'man page' for consistency.

Some mdoc(7) fixes:

Nuke incorrect usage of .Ar; replace it with .Vt, .Va or .Fa appropriately.

Fixed some bitrot. The KSE interface change for vops had not reached here.

Didn't fix older bugs. Most of the examples don't even match historical
interfaces.

mdoc(7) police: Use the new .In macro for #include statements.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

Fixed bitrot in synopsis. The prototype for VOP_ISLOCKED() changed

Fixed bitrot in synopsis.

Document the flags and p parameters to VOP_LOCK and VOP_UNLOCK. Also,
at Doug Rabson's suggestion, add vn_lock(9) as an alternative name for
this manpage and note its calling convention.

Typo police.

This is the current draft of my filesystem manpages. Some files are
incomplete and some are just placeholders but I wanted to try to get
something at least into 2.2 on the grounds that what I have is a lot
better than nothing. I also wanted to commit something which documents
the interfaces in 2.2 before I start updating the documentation for 3.0.

This is a definite 2.2 candidate and is also relavent to 2.1 if people
still care about that branch.
