switch groff parameter -man to -mandoc for new groff release 1.23.0
PR: 273565

Remove $FreeBSD$: two-line nroff pattern

Remove /^\.\\"\n\.\\"\s*\$FreeBSD\$$\n/

Minor mdoc improvements.

mdoc: sort prologue macros.

Don't use col(1) since grotty(1) never outputs reverse line feeds,
and because col(1) mangles ANSI color escapes if enabled. Spaces
to tabs compression is now done by passing -h to grotty(1).

Discussed with: uqs

Typo.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Implementaiton of man, manpath, whatis, and apropos written entirely in sh.

Features of this new version in favor of the old one:
BSD licensed -- old one is GPL.
Imports configuration from /etc/man.conf and LOCALBASE/etc/man.d/*.conf
allowing ports to extend the base functionality. The pluggable
configuration can supplement the manual search path (retiring use.perl),
add locales, and override language specific toolsets (attempt to merge
the japanese/man port into the base system as much as possible).

Much effort has been made to make this version mirror the functionality
of the existing implementation. For 99% of users, it should be a drop in
replacement.

Finish importing Lite2's src/usr.bin, except for ex, diff, grep, mail,
pascal and vmstat.sparc. All changed files on the vendor branch should
already have been imported.

This commit was generated by cvs2svn to compensate for changes in r13122,
which included commits to RCS files with non-trunk default branches.
