This is really lame. The Ruby OAuth2 client can only pass its token in
the form data (which Phab is not prepared to accept), or as part of the
Authorization header (which PHP strips out).

Use a function only available in newer PHP to scrape the Authorization
header from the raw stream.

I have no idea what the correct fix is.
