Mk/**ruby.mk: Switch from USE_RUBY=yes to USES=ruby

Switch from Mk/bsd.ruby.mk to Mk/Uses/ruby.mk

Notable changes are.

- Mk/bsd.ruby.mk is moved to Mk/Uses/ruby.mk.
- USE_RUBY=yes is replaced with USES=ruby.
- USE_RUBY_EXTCONF is replaced with USES=ruby:extconf.
- USE_RUBY_RDOC is replaced with USES=ruby:rdoc.
- USE_RUBY_SETUP is replaces with USES=ruby:setup.
- RUBY_NO_BUILD_DEPENDS and RUBY_NO_RUN_DEPENDS are replaced with
  USES=ruby:{build,none,run}.
- RUBY_REQUIRE isn't used anywhere, so removed.
- USES=gem now implies USES=ruby.

This is mainly the work of yasu@ at https://reviews.freebsd.org/D27863

I have just made some cosmetic changes and ran exp-run to test that the
tree is not in a BROKEN state.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

- Update MASTER_SITES and unbreak this port

Mark as broken: does not fetch

Cleanup plist

- Add staging support
- Remove leading article from COMMENT
- Don't define ETCDIR, it's done by ports framework
- Define DOCS EXAMPLES options

Add NO_STAGE all over the place in preparation for the staging support (cat:
dns)

Style: tab -> space.

Most contributors copy an existing port when writing their own so reduce the
number of bad examples in the tree.

Move the rc.d scripts of the form *.sh.in to *.in

Where necessary add $FreeBSD$ to the file

No PORTREVISION bump necessary because this is a no-op

In the rc.d scripts, change assignments to rcvar to use the
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().

In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.

- Return my ports back to the pool.  I was unable to make any fixes to
  my ports in the past 3 weeks while ports were broken on any 10.x
  machines, which means I'm unable to maintain them.  So let people know
  that there's no available support for them until things are back to
  normal (which also means that anyone with spare time will be able
  to fix them without getting approval).

- Get Rid MD5 support

Begin the process of deprecating sysutils/rc_subr by
s#. %%RC_SUBR%%#. /etc/rc.subr#

Fix a few "bad example" problems in the rc.d scripts that have been
propogated by copy and paste.

1. Primarily the "empty variable" default assignment, which is mostly
${name}_flags="", but fix a few others as well.
2. Where they are not already documented, add the existence of the _flags
(or other deleted empties) option to the comments, and in some cases add
comments from scratch.
3. Replace things that look like:
prefix=%%PREFIX%%
command=${prefix}/sbin/foo
to just use %%PREFIX%%. In many cases the $prefix variable is only used
once, and in some cases it is not used at all.
4. In a few cases remove ${name}_flags from command_args
5. Remove a long-stale comment about putting the port's rc.d script in
/etc/rc.d (which is no longer necessary).

No PORTREVISION bumps because all of these changes are noops.

- Change my email.

PR:             ports/101672
Submitted by:   Stanislav Sedov <ssedov at mbsd.msk.ru>

Remove the FreeBSD KEYWORD from all rc.d scripts where it appears.
We have not checked for this KEYWORD for a long time now, so this
is a complete noop, and thus no PORTREVISION bump. Removing it at
this point is mostly for pedantic reasons, and partly to avoid
perpetuating this anachronism by copy and paste to future scripts.

- Add SHA256

- Better use of USE_RC_SUBR infrastructure

With portmgr hat on, reset maintainership of knu's ports since he has
been inactive more than 6 months.  We hope to see him back sometime.
