- 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.

Add missing static keywords to catman(1)

For POLA reasons, disable SGR sequences in catpages.

See r222647 for a similar change to bsd.doc.mk after SGR was generally
turned on in groff.

Unbreak catman(1) by removing calls to col(1).

col(1) was mangling the SGR escapes and is not strictly required.

See r222647, r222648, r222650, and r222653 for more details.

Modernize scandir(3) and alphasort(3) interfaces according to the IEEE
Std 1003.1-2008. Both Linux and Solaris conforms to the new definitions,
so we better follow too (older glibc used old BSDish alphasort prototype
and corresponding type of the comparision function for scandir). While
there, change the definitions of the functions to ANSI C and fix several
style issues nearby.

Remove requirement for "sys/types.h" include for functions from manpage.

POSIX also requires that alphasort(3) sorts as if strcoll(3) was used,
but leave the strcmp(3) call in the function for now.

Adapt in-tree callers of scandir(3) to new declaration. The fact that
select_sections() from catman(1) could modify supplied struct dirent is
a bug.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Restore the check against running as root that I accidentally removed in
r194493.

When checking if we can write to a file, use access() instead of a
manual permission check based on stat output. Also, get rid of the
executability check since it is not used.

Prepare for MACHINE and hw.machine switching to "pc98" on FreeBSD/pc98.

Sync program's usage() with manpage's SYNOPSIS.

Added the EXIT STATUS section where appropriate.

Look into machine-specific manpage subdirectories too.

Fixed the only warning and mark as WARNS=6 clean.

- Fixed handling of manpage subdirectories:

catman /usr/share/man/man8
cd /usr/share/man; catman man8

- Don't print false warnings about invalid cat pages which are
machine-specific cat page subdirectories (visible with -v).

- Fixed one memory leak.

Add (unsigned char) cast to ctype macros

Use setlocale & nl_langinfo to parse locale name

Remove deprecated locale names

Fixed catman(1) so that if the source files are compressed,
the preformatted files are compressed with the same program
as the source, and if the source files are uncompressed, the
preformatted files are also uncompressed.

mdoc(7) police: sort xrefs in SEE ALSO.

Mostly support alternate manpage zipping.

Revert last delta. SGR support in grotty(1) is disabled system-wide
in /usr/share/tmac/troffrc pending the issue resolution on -arch.

Groff 1.18.1 comes in with ANSI color support, enabled by default.
In "nroff" mode, italic font renders as an underlined text, which
makes it indistinguishable from the bold text on color monitors
(cons25 terminal type), yet it requires the less(1)'s -R option.
(Refer to the new grotty(1) manpage for details.)

So turn off the color support for now (when generating catpages),
until we figure out what do we do with this new feature. I have
a patch for grotty(1) that tells it to use the "reverse video"
attribute to render the italic font. Once this is accepted, we
can turn color support back on (if there won't be any objections
from the community).

No need to declare optind as an external int.

mdoc(7) police: tidy up.

Add C rewrites of catman and makewhatis. These aren't quite as
the submitter supplied them, as I did some WARNS=n fixups (mostly
const-ification).
