Updates the specification tests to match the official new format.

[atheriel]

I tried to run the test suite locally against the specification, and noticed that it no longer works. The upstream specifications repo changed the JSON format of the test suite in c6d7ac8 -- to be precise, the keys have changed from "extjson" and "bson" to "cannonical_extjson" and "cannonical_bson", respectively, and the 128-bit tests are now in the main directory.

~This commit just moves the existing infrastructure to the new names.~

~(Note that a number of tests still fail -- I have about 1250 OKs and 30 errors locally for the specification context. I'm looking into fixing those failing tests as well.)~

The first commit just moves the existing infrastructure to the new names. Subsequent commits fix the existing failures.

FYI I don't think the tests ever passed 100%. The mongodb folks told me this was expected because the c driver doesn't implement the entire spec.

[atheriel]

That's good to know. I'm interested in modifying the tests so that they account for this and track expected failures as well -- does that make sense? I'd very much like to use the spec tests to experiment with the out-of-tree changes mentioned in #37.

(Travis errors look spurious.)

[atheriel]

I have updated the branch to include fixes to all existing spec tests. I now have 1162 passes and zero failures locally.

Wow that is impressive. Without editing mongolite or jsonlite?

[atheriel]

Ah, I realize that the binary tests only pass with my changes to jsonlite. I'll fix that.

[jeroen]

Could you update the specifications module to the latest version?

[atheriel]

Yep, done. And I've fixed the binary representation issue, along with adding an informative comment.

OK cool. I seem to have broken the Windows build in master but that is unrelated to this PR.
