- 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 csplit(1)

A bit of rewording for clarity, taken from OpenBSD.

Submitted by: jmc@OpenBSD.org

Update the description of -k, output files appear to
be left regardless of an error, signal, or complete
run.

Document input line length limit.

Sort sections.

Added the EXIT STATUS section where appropriate.

Remove BUGS section that talked about missing multibyte character support.
We have support now that the regular expression routines do.

Document missing multibyte character support in utilities specified
by POSIX.

Use fseeko() to properly support large files.

Use errc().

mdoc(7) police: simplify.

The return value of snprintf should be always nonnegative, so it should
be safe to cast it to a size_t before comparing it to a sizeof().

Use sigaction(2) instead of signal(3) to avoid the signal handler being
re-entered.

Avoid truncating filenames with snprintf().

Note that this appeared at least as early as PWB UNIX.

Use the literal string 'PWB UNIX', as we still have no .At macro for it.

Respect LC_CTYPE and LC_COLLATE environment variables, mainly for their
effects on regular expressions. The libc regex code does not handle
equivalence classes well (for example), but we do our best.

mdoc(7) police: markup polishing.

Handle the case where a negative offset in a regular expression match
is larger than the number of lines in the overflow file.

Correct synopsis and usage(): pattern arguments are not optional.

Add the csplit(1) utility, which splits files based on context, as specified
by SUSv3.

This Makefile got left out of the previous commit.
