- 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.

Build swapon with WARNS=6.

Don't use a variable called stat, because it collides with stat(2).

Raise WARNS for various tools where possible.

- Change the meaning of -h flag from giving the output in megabytes to
giving the output in a human-readable form. This behaviour is consistent
with most of system tools.
- Add -m and -g options to give output in megabytes and gigabytes
respectively.

Add 'swapctl' - as a hardlink to swapon/swapoff, and augment swapon with
swapctl functionality. The idea is to create a swapctl command that is
fairly close to the OpenBSD and NetBSD version. FreeBSD does not implement
swap priority (and it would be a mistake if we did) so we didn't bother with
that part of it.

This is David Schultz's swapoff code which I am finally able to commit.
This should be considered highly experimental for the moment.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for sbin/ to 8.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.

This commit was generated by cvs2svn to compensate for changes in r1558,
which included commits to RCS files with non-trunk default branches.
