Initial cut of support for python 2. Notable deficiencies: - Removes keyword-only args from several API functions. - Changes `BytesIO.getbuffer()` to `BytesIO.getvalue()`. This is almost certainly a significant performance regression for large loads. At the very least, it should be made conditional by python version. It's an open question whether the extra copy incurred by calling `getvalue()` makes this even worth doing. If not, we'd probably have to vendor a py2-compat BytesIO-like object to support zero-copy reads.

Not sure if this is actually worth doing, but, I was seeing unreasonable memory usage for fundamentals queries on Q over the weekend, and wanted to at least test to see if warp_prism improved that situation. |

In Python 2 cStringIO has a C API where you can read from the underlying buffer. There is a capsule called Even with the |

Don't know, I haven't actually used this yet other than getting the tests to pass in py2. |

BytesIO.getbuffer()toBytesIO.getvalue(). This is almostcertainly a significant performance regression for large loads. At the
very least, it should be made conditional by python version. It's an
open question whether the extra copy incurred by calling
getvalue()makes this even worth doing. If not, we'd probably have to vendor a
py2-compat BytesIO-like object to support zero-copy reads.
