epriestley 3aa17c7443 Prevent CSRF uploads via /file/dropupload/
Summary:
We don't currently validate CSRF tokens on this workflow. This allows an
attacker to upload arbitrary files on the user's behalf. Although I believe the
tight list of servable mime-types means that's more or less the end of the
attack, this is still a vulnerability.

In the long term, the right solution is probably to pass CSRF tokens on all Ajax
requests in an HTTP header (or just a GET param) or something like that.
However, this endpoint is unique and this is the quickest and most direct way to
close the hole.

Test Plan:
  - Drop-uploaded files to Files, Maniphest, Phriction and Differential.
  - Modified CSRF vaidator to use __csrf__.'x' and verified uploads and form
submissions don't work.
