Added bundler as default gems. Revisit [Feature #12733]
* bin/*, lib/bundler/*, lib/bundler.rb, spec/bundler, man/*:
Merge from latest stable branch of bundler/bundler repository and
added workaround patches. I will backport them into upstream.
* common.mk, defs/gmake.mk: Added `test-bundler` task for test suite
of bundler.
* tool/sync_default_gems.rb: Added sync task for bundler.
