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.

Remove VOP_VPTOFH(9) from references in VFS(9), as it's a VOP,
not VFS operation.

Catch up with the VFS_VPTOFH(9) -> VOP_VPTOFH(9) repocopy that happened
almost three years ago in r166794.

Don't cross-reference VFS_START.9

Expand *n't contractions.

Mdoc Janitor:

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

Uniformly refer to a file system as "file system".

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...

Document VFS changes:

VFS_CHECKEXP.9, now used to check export credentials
VFS_FHTOVP.9, only used for filehandle to vnode, no access checks are done.
VFS.9, inform people of the vfs_std* functions available to avoid
ugly casts to eopnotsup and making of dummy functions to return 0.

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.
