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.

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.

devel: remove 'Created by' lines

Remove # $FreeBSD$ from Makefiles.

Convert USES=gem:autoplist to USES=gem since autoplist is default

create USES=gem and update rubygem- ports to use it

Note that for now ports still have to have USE_RUBY=yes to use USES=gem

many ruby/rubygem ports: death of rubyforge.org

rubyforge.org shutdown on May 15, 2014. This commit accounts for that by doing
several things:

- Deprecate ruby that had only rubyforge.org as MASTER_SITES (and so are now
  only fetchable via our cache)
- Deprecate ports that depend on those
- Update the WWW pkg-descr line that points to rubyforge.org for rubygem ports
  (which are still fetchable from rubygems.org)

The next step will be to remove rubyforge.org from bsd.sites.mk, after these
deprecated ports are deleted.

- Implement new knobs for gems and rake (these are included in
  ruby 1.9 distribution already). Also move gem bits from
  ruby-gems/Makefile.common to bsd.ruby.mk[1]. Now to depend
  on gems or rake you should define USE_RUBYGEMS/USE_RAKE
  accordingly. Also RAKE_BIN variable is provided for
  pointing to the right rake executable.
