Updated RubyGems to 2.1.10.

  Masahiro Tomita, Issue #668 by Kouhei Sutou.

* RubyGems now allows a Pathname for Kernel#require like the built-in
  Kernel#require.  Pull request #663 by Aaron Patterson.

  1.9.1 is no longer receiving security fixes, so please update to a newer
  version.)  Issue #676 by Michal Papis.  Issue wayneeseguin/rvm#2262 by
  Thomas Sänger.

=== 2.1.5 / 2013-09-24

Security fixes:

* RubyGems 2.1.4 and earlier are vulnerable to excessive CPU usage due to a
  backtracking in Gem::Version validation.  See CVE-2013-4363 for full details
  including vulnerable APIs.  Fixed versions include 2.1.5, 2.0.10, 1.8.27 and

=== 2.1.0 / 2013-09-09

Security fixes:

* RubyGems 2.0.7 and earlier are vulnerable to excessive CPU usage due to a
  backtracking in Gem::Version validation.  See CVE-2013-4287 for full details
  including vulnerable APIs.  Fixed versions include 2.0.8, 1.8.26 and
  1.8.23.1 (for Ruby 1.9.3).  Issue #626 by Damir Sharipov.

Major enhancements:

* RubyGems uses a new dependency resolver for gem installation which works
  similar to the bundler resolver.  The new resolver can resolve conflicts the
  previous resolver could not and offers improved diagnostics when conflicts
  are discovered.

Minor enhancements:

* RubyGems now has improved platform matching for the ARM architecture.  Gems
  built with a CPU of "arm" will match any specific ARM CPU.  See `gem help
  platform` for further details.  Fixes #532 by Kim Burgestrand.
* The --version option now accepts compound requirements the same as in a gem
  dependency.  The following invocation will install rails between 4.0.0.beta
  and 4.2:

    gem install rails -v '>= 4.0.0.beta, < 4.2'

  Fixes #531 by Gary S. Weaver
* `gem clean` now allows `-n` as an alias for `--dryrun`.  Pull Request #517
  by Gastón Ramos
* Added `gem update --system` to `gem help`.  Pull Request #514 by Vince
  Wadhwani
* Added PATH to `gem env` output.  Pull Request #490 by Michal Papis
* Added --host option to `gem owner` to match other commands using the
  gemcutter API.  Pull Request #462 and issue #461 by Hugo Lopes Tavares
* Added --abort-on-dependent to `gem uninstall`.  This will abort instead of
  asking to uninstall a gem that is depended upon by another gem.  Pull
  request #549 by Philip Arndt.
* RubyGems no longer alters Gem::Specification.dirs when installing.  Based on
  Pull Request #452 by Vít Ondruch
* RubyGems uses ENV['MAKE'] or ENV['make'] over rbconfig.rb's make if present.
  Pull Request #443 by Erik Hollensbe
* RubyGems can now save remote source cache files in an alternate directory
  controlled by `ENV["GEM_SPEC_CACHE"]`.  Pull Request #489 by Michal Papis
* Generated private keys are now encrypted.  Pull Request #453 by pietro
* Separated Gem::Request from Gem::RemoteFetcher.  Pull Request #283 by Steve
  Klabnik.
* RubyGems indicates when a .gem's content is corrupt while verifying.  Bug
  #519 by William T Nelson.
* Refactored common installer setup.  Pull request #520 by Gastón Ramos
* Moved activation tests to Gem::Specification.  Pull request #521 by Gastón
  Ramos
* When a --version option with a prerelease version is given RubyGems
  automatically enables prerelease versions but only the last version is
  used.  If the first version is a prerelease version this is no longer sticky
  unless an explicit --[no-]prerelease was also given.  Fixes part of #531.
* RubyGems now supports an SSL client certificate.  Pull request #550 by
  Robert Kenny.
* RubyGems now suggests how to fix permission errors.  Pull request #553 by
  Odin Dutton.
* Added support for installing a gem as default gems for alternate ruby
  implementations.  Pull request #566 by Charles Nutter.
* Improved performance of Gem::Specification#load by caching the loaded
  gemspec.  Pull request #569 by Charlie Somerville.
* RubyGems now warns when an unsigned gem is verified if -P was given during
  installation even if the security policy allows unsigned gems and warns when
  an untrusted certificate is seen even if the security policy allows
  untrusted certificates.  Issue #474 by Grant Olson
* RubyGems can now rewrite executables with or without a shebang of
  /usr/bin/env via <code>gem pristine --all --only-executables
  --env-[no-]shebang</code>.  Issue #579 by Paul Annesley.
* RubyGems can now run its tests without OpenSSL.  Ruby Bug #8557 by nobu.
* Improved performance by caching Gem::Version objects and avoiding
  method_missing in Gem::Specification.  Pull request #447 by Jon Leighton.
* Files in a .gem now preserve their modification times.  Pull request #582 by
  Jesse Bowes
* Improved speed of looking up dependencies in SpecFetcher through
  Array#bsearch (when present).  Pull request #595 by Andras Suller
* Added `--all` option to `gem uninstall` which removes all gems in GEM_HOME.
  Pull request #584 by Shannon Skipper.
* Added Gem.find_latest_files which is equivalent to Gem.find_files but only
  returns matching files from the latest version of each gem.  Issue #186 by
  Ryan Davis.
* Improved performance of `gem outdated` by reducing duplicate work (it is
  still slow, but I see a near 50% improvement for 250 gems on a fast
  connection).  See also Gem::Specification::outdated_and_latest_version

Bug fixes:

* rubygems_plugin.rb files are now only loaded from the latest installed gem.
* Fixed Gem.clear_paths when Security is defined at top-level.  Pull request
  #625 by elarkin
* Fixed credential creation for `gem push` when `--host` is not given.  Pull
  request #622 by Arthur Nogueira Neves
