libruby1.9.1 shouldn't install ruby - remove ruby1.9.1

[Javier López]

Release of Ubuntu: Vivid, Trusty
Package Version: ruby1.9.1
Expected Results: vim-nox or any other program who depends on libruby should install the library but not the whole ruby programming language
Actual Results: vim-nox install ruby since it depends on libruby and libruby depends on ruby

According to:

               ruby1.9.1 (1.9.3.484-2) unstable; urgency=medium

                 * new strategy for Ruby version transitions:
                   - ruby1.9.1 depends on ruby
                   - libruby1.9.1 depends on ruby1.9.1
                 * Drop alternatives entries.

libruby1.9.1 now depends on ruby1.9.1. This causes than installations of packages such us vim-nox (who depends on libruby) pull the whole ruby programming language.

In my opinion it shouldn't be this way (unless the transition fixes some important bugs). It could be suggested but not forced. vim-nox also depends on liblua and its installation doesn't pull the Lua programming language into the system.

This was fixed in ruby2.1 in Debian a while ago, and ruby1.9.1 is unmaintained and obsolete. We won't fix anything there any more, just remove it. The only remaining reverse dependencies are

  - facter-customfacts-plugin: facter-plugins does not exist in Debian and is obviously unmaintained according to https://launchpad.net/ubuntu/+source/facter-plugins/+changelog

 - ruby-notmuch from source notmuch; in Debian a newer version depends on libruby2.1, but this version fails to build: https://launchpad.net/ubuntu/+source/notmuch/0.18.2-1

So sorting out these two is obviously the better way forward here.

Removing packages from wily:
 facter-plugins 1.1-0ubuntu3 in wily
  facter-customfacts-plugin 1.1-0ubuntu3 in wily amd64
  facter-customfacts-plugin 1.1-0ubuntu3 in wily arm64
  facter-customfacts-plugin 1.1-0ubuntu3 in wily armhf
  facter-customfacts-plugin 1.1-0ubuntu3 in wily i386
  facter-customfacts-plugin 1.1-0ubuntu3 in wily powerpc
  facter-customfacts-plugin 1.1-0ubuntu3 in wily ppc64el
Comment: unmaintained for years, not in Debian, depends on obsolete ruby1.9.1

notmuch builds with ruby 2.2 already.
