Add ruby-single.eclass
This eclass supports the case where a single RUBY interpreter is
sufficient. Code in common with ruby-ng.eclass has been refactored
into a common ruby-utils.eclass.

+# @BLURB: An eclass for installing Ruby packages with proper support for
multiple Ruby slots.
+# @DESCRIPTION:
+# The Ruby eclass is designed to allow an easier installation of Ruby packages
+# and their incorporation into the Gentoo Linux system.
+#
+# Currently available targets are:
+# * ruby18 - Ruby (MRI) 1.8.x
+# * ruby19 - Ruby (MRI) 1.9.x
+# * ruby20 - Ruby (MRI) 2.0.x
+# * ruby21 - Ruby (MRI) 2.1.x
+# * ree18 - Ruby Enterprise Edition 1.8.x
+# * jruby - JRuby
+# * rbx - Rubinius
+#
+# This eclass does not define the implementation of the configure,
+# compile, test, or install phases. Instead, the default phases are
+# used. Specific implementations of these phases can be provided in
+# the ebuild either to be run for each Ruby implementation, or for all
+# Ruby implementations, as follows:
+#
+# * each_ruby_configure
+# * all_ruby_configure
+
+# @ECLASS-VARIABLE: USE_RUBY
+# @DEFAULT_UNSET
+# @REQUIRED
+# @DESCRIPTION:
+# This variable contains a space separated list of targets (see above) a
package
+# is compatible to. It must be set before the `inherit' call. There is no
+# default. All ebuilds are expected to set this variable.
+
+# @ECLASS-VARIABLE: RUBY_PATCHES
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# A String or Array of filenames of patches to apply to all implementations.
+
+# @ECLASS-VARIABLE: RUBY_OPTIONAL
+# @DESCRIPTION:
+# Set the value to "yes" to make the dependency on a Ruby interpreter
+# optional and then ruby_implementations_depend() to help populate
+# DEPEND and RDEPEND.
+
+# @ECLASS-VARIABLE: RUBY_S
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If defined this variable determines the source directory name after
+# unpacking. This defaults to the name of the package. Note that this
+# variable supports a wildcard mechanism to help with github tarballs
+# that contain the commit hash as part of the directory name.
+
+# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If defined this variable contains a whitelist of shared objects that
+# are allowed to exist even if they don't link to libruby. This avoids
+# the QA check that makes this mandatory. This is most likely not what
+# you are looking for if you get the related "Missing links" QA warning,
+# since the proper fix is almost always to make sure the shared object
+# is linked against libruby. There are cases were this is not the case
+# and the shared object is generic code to be used in some other way
+# (e.g. selenium's firefox driver extension). When set this argument is
+# passed to "grep -E" to remove reporting of these shared objects.
