libjail is pretty small, so it makes for a good proof of concept demonstrating
how a system library can be wrapped to create a loadable Lua module for flua.
* Introduce 3lua section for man pages
* Add libjail module

In case we are trying to read a catpage, the manpage variable is not defined.
It results in the "cattool" having no arguments.
In case the catpage is compressed, the cattool used is "zcat" which dies if the
standard input is a terminal, meaning the function calling it is exiting as if
there were no ".so"
In case the catpage is uncompressed, the cattool used is "zcat -f" which waits
reading standard input, making the man(1) command hang.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.

If MANPATH begins with a colon, it is appended to the default list; if it ends
with a colon, it is prepended to the default list; or if it contains two
adjacent colons, the standard search path is inserted between the colons. If
none of these conditions are met, it overrides the standard search path.

localbase is not consistent with base for manpages:
/usr/local/man vs /usr/share/man adding share/man allows to fix that
inconsistency and would permit to remove tons of patches/modifications in the
ports tree
If apropos(1) and whatis(1) are not hardlinks to man(1) that means the system is

- Compatiblity with existing manpages has been improved
- Now support ".so" directive with compressed manpages (which fixes a regression
we have since we have new man(1))
man(1) now first test the manpage to run with mandoc to make sure it can be
rendered.
In case groff cannot be found (because base has been built WITHOUT_GROFF) it
recommands to install groff from the packages
in grotty(1). This makes it possible to view colorized manpages in
color.
When MANPAGER environment variable is set, use it instead of PAGER.
Why another environment variable, one might ask? With color output
enabled, both a terminal and a pager should support the ANSI color
escapes. On a supporting terminal, less(1) with option -R would be
such a pager, while "more -s" (the current default pager for man(1))
will show garbage. It means a different default pager is needed when
color output is enabled, but many people have PAGER set customary,
and it's unlikely to support ANSI color escapes, so introducing yet
another variable (MANPAGER) seemed like a good option to me:
- if MANPAGER is set, use that unconditionally;
- if you disable color support (it is by default), and don't set
MANPAGER, you get an old behavior: -P pager, $PAGER, "more -s",
in that order;
- if you enable color support (by setting MANCOLOR), and don't set
MANPAGER, we ignore PAGER which is unlikely to support ANSI color
escapes, and you get: -P pager, "less -Rs", in that order;
- you might have good reasons for different man(1) and general
purpose pagers;
- later versions of GNU man(1) support MANPAGER.
If set to a numeric value, used as the width manpages should be
displayed. Otherwise, if set to a special value ``tty'', and
output is to a terminal, the pages may be displayed over the
whole width of the screen.
Let groff pass the -c flag to grotty, which will turn off ANSI
sequences. While these are not a problem for our more/less, they get
mangled by col(1) and this will result in garbage output.
This makes man(1) work together with textproc/groff, in case the
user decided to delete the old groff from base (-DWITHOUT_GROFF).
Use locale(1) to determine the locale instead of trying to hand roll it.
Correctly construct groff call based on charset and locale independently,
not the mix between the two.

also in the base set, the man utility when invoked with -a would display
pages for each locale in the same tree:
$ LANG=en_GB.ISO8859-15 man -wa man
/usr/share/man/en.ISO8859-15/man1/man.1.gz
/usr/share/man/man1/man.1.gz
/usr/share/man/en.ISO8859-15/man7/man.7.gz
/usr/share/man/man7/man.7.gz
Use continue to break out of the loop for the current locale. This results
in behavior more closely matching the old GNU man implementation:
$ LANG=en_GB.ISO8859-15 man -wa man
/usr/share/man/en.ISO8859-15/man1/man.1.gz
/usr/share/man/en.ISO8859-15/man7/man.7.gz
This will still search for a copy of the file in other manual path
locations. If there was a /usr/local/man/man1/man.1.gz file, it would still
be displayed. This is also consistent with the GNU man implementation.

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.
