- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Remove outdated piece of information.

devtoname() always returns a pathname to the device. It will never
return a #major/minor string.

Remove remnants of dev_t.

These functions take a `struct cdev *' -- not a dev_t. Inside the
kernel, dev_t has the same use as in userspace, namely to store a device
identifier.

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.

Mdoc Janitor:

* Fix hard sentence breaks.

* NOTE: devstat(9) requires more mdoc(7) work.

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...

mdoc(7) police: normalize .Nd.

Fixed missing and/or wrong and/or extra includes in synopsis.

Fill in a missing word (`it').

Remove a useless new line.

Document the devtoname(9) kernel interface.
