commit 854d71c1420eb80ec79755a6cdf829f3f39aead7
Author: Ryan Harrison <rharrison@chromium.org>
Date: Wed Oct 18 16:41:35 2017

Refactor HasXFAField into HasFormInfo

The existing API is too restrictive for collection the metrics
information that we want. Specifically it only tells us if there are
XFA forms in the document, but not AcroForms. This refactoring makes
the method more general, so that non-XFA information is provided
also. This change in semantics of the return value required some
changes at the call sites of the API.
