phabricator: add the uploadfile function

This is needed to be able to submit binary files such as images in commits (and
also non-UTF-8 text files).  One of the primary disadvantages of the current
use of createrawdiff is that Phabricator simply drops any binary diffs included
in the patch, but not the files, so if such a diff is then committed it
corrupts any binary files in it.
