[Ironruby-core] Status of rubygems unit tests

I have been working on making  the rubygem unit tests (from git://github.com/vvs/rubygems.git) pass with IronRuby. When I started, the results looked like this.

707 tests, 1170 assertions, 9 failures, 352 errors, 1 skips

Half the tests (9+352/707) were failing (or half were passing depending on how you want to look at it). The main culprits were Zlib::GzipWriter, YAML.quick_emit and Zlib::Deflate. After fixing these issues, the results look like this:

707 tests, 1881 assertions, 40 failures, 53 errors, 4 skips

It's a good improvement. Errors (where the tests cannot even run properly) account for 8% (53/707), and failures (functionality defects) can now show through - in 5% (40/707) of the tests, for a pass rate of 87%. The errors are because of the following exceptions in descending order of occurrence. The number at the start is the count of how often the error happened.

9: dump format error(9)
8: ERROR: Failed to build gem native extension.
5: dump format error(8)
5: marshal data too short
4: uninitialized constant OpenSSL::X509
2: uninitialized constant OpenSSL::PKey
2: trying to seek on a non-existent stream?
2: ERROR: Failed to build gem native extension.
2: SSL is not installed on this system
2: SocketError: An established connection was aborted by the software in your host machine

I will keep pushing on the tests. The failures will be a bit more work to narrow down as some expectation fails, possibly much after a bug introduced a bad result in the system. If anyone wants to help dig into the failures, let me know, and I can help you get set up.
