ruby subpackages now are generated by a macro. This reduces the
Makefile size by half and the chance of errors.

No change in packages contents, install-size or dependencies, except
for some removed doc files.

Relevant changes for OpenWRT:

* all patches for ruby-core where merged upstream and
  they are not needed anymore (only rdoc patch remains)
 - PR for the rdoc github project was added to the patch header
   (https://github.com/rdoc/rdoc/pull/340)
* new package ruby-powerassert for introduced new bundled gem power_assert
* new package ruby-unicodenormalize for Unicode normalization files
* removed ruby-dl as DL was removed after being deprecated
* ruby-{minitest,testunit} where removed from ruby library. Now they
  are bundled gems
* test and sample files where removed from gems in order to save resources
  and reduce pkgs dependencies
* script ruby_find_pkgsdeps was updated to match upstream changes

ruby_find_pkgsdeps: look for file dependencies (checks
require and Encoding references) and extrapolate it to pkgs
deps. Also checks whether a dep is redundant or missing in pkgs.
Must run inside an OpenWRT with all ruby* pkgs installed.

ruby_missingfiles: list files in staging/target and from files
comparing side by side its contents. It helps to easly visualize
which file is not packaged in an ipk.
