Introduce specific release labels.
Every build has a release date.
Handle release label and date from git, release tar, or random tar.
Added 'monthly' binary build tasks.
Fixes for binary packaging and release labels.
Check return value of __cxa_demangle.
Default version is 1.9.
Removed pre-installed ffi gems.

The current versions of the ffi gem install on Rubinius. These
gems were bundled to try to help transitioning from the built-in
Rubinius FFI to the gem. But as with most things that hide
potential problems, this is likely more trouble than good. Better
to force projects on ffi pre-1.2 to update.
Vendored libyaml 0.1.4.
Added .gitignore for libyaml.
Added feature flags for vendored libyaml.
-X<version> is dead.
Checking for language mode no longer requires access to state.
Use language mode macros in the JIT code.
More -X<version> cleanup.
Rebuild load_order indexes when signature changes.
Added package tasks for Heroku.
Added 'rake travis' for Travis CI.
More -X<version> cleanup.
Updated rubygems to 2.0.4.

=== 2.0.3 / 2013-03-11

* Bug fixes:
  * Reverted automatic upgrade to HTTPS as it breaks RubyGems APIs.  Fixes
    #506 by André Arko

    Cochran.

=== 2.0.0 / 2013-02-24

RubyGems 2.0 includes several new features and many breaking changes.  Some of
these changes will cause existing software to break.  These changes are a
result of improvements to the internals of RubyGems that make it more
maintainable and improve APIs for RubyGems users.

If you are using bundler be sure to install a 1.3.0.prerelease version or
newer.  Older versions of bundler will not work with RubyGems 2.0.

Changes since RubyGems 1.8.25 (including past pre-releases):

* Breaking changes:

  * Deprecated Gem.unresolved_deps in favor of
    Gem::Specification.unresolved_deps

  * Merged Gem::Format into Gem::Package.  Use Gem::Package.new instead
    of Gem::Format.from_file_by_path

    automatically detect old gems for you, so there is no need to refer to it.

  * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
    documentation.
  * Add ability to install gems directly from a compatible gemdep
    file (Gemfile, Isolate, gem.deps.rb)
    <code>gem install --file path</code>
  * Add ability to load gem activation information from a gemdeps
    file (Gemfile, Isolate, gem.deps.rb).
    Set RUBYGEMS_GEMDEPS=path to have it loaded. Use - as the path
    to autodetect (current and parent directories are searched).

* Minor enhancements:
  * Added `gem check --doctor` to clean up after failed uninstallation.  Bug
    #419 by Erik Hollensbe
  * RubyGems no longer defaults to uninstalling gems if a dependency would be

    (baroquebobcat)
  * Corrupt or bad cached specs are now re-downloaded. (cookrn)
