- 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.

mdoc(7): Use the new feature of the .In macro.

Warns fixes. Mainly unused headers/params/vars removal, but also

Tidy up usage message.

Replace an alloca() call with a slightly more standard malloc()/free()
pair.

Remove unnecessary compatibility macro. (We were only printing, not parsing,
intmax_t.)

Add new 1003.1-2001/TC1/D6 parameters. (On final recirculation ballot now,
so this should be officially TC1 before the New Year.)

Add TrustedBSD pathconf parameters.

Add compilation support for -stable (to be merged momentarily).

Completely revamp the way getconf(1) works, for better adherence to the
intent of the Standard.

- Make getconf able to distinguish between configuration variables which
are entirely unknown and those which are merely not defined in the
compilation environment. The latter now get a more appropriate
"undefined\n" result rather than a diagnostic. This may not be
exactly right, but it's closer to the intent of the Standard than
the previous behavior.

- Support ``programming environments'' by validating that the environment
requested with the `-v' flag is the one-and-only execution environment.
(If more environments are supported for some platforms in the future,
multiple getconf(1) executables will be required, but a simple edit in
progenv.gperf will enable automatic support for it.) Document POSIX
standard programming environments.

- Add all of the 1003.1-2001 configuration variables. FreeBSD does not
support all of these (including some that are mandatory); getconf will
later be fixed to break the world should a required variable not be
defined.

As a result of all these changes, gperf is no longer adequate. Keep the
overall format and names of the files for now, to preserve revision history.
Use an awk script to process the .gperf files into C source, which does a
few things that gperf, as a more general tool, cannot do. The keyword
recognition function is no longer a perfect hash function.

This may obviate the need for gperf in the source tree.

- Add a small compile-time regression test to break the build if any of the
.gperf files declare conflicting token sets. (gperf itself would have done
this for the simple case of duplicate tokens in the same input file.)

Make obrien happy. Add a bad awk script which emulates as much of
gperf's behavior as we ever actually needed here. This generates
a much-less-efficient keyword recognizer, but it's not like that matters
in this application. Makefile changes coming once this passes the world
test.

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

Hello, getconf. This is a slight reinvention of the

more complicated than necessary.
