Changes to XFA to more closely match master.

These files should change in XFA in order to reduce the number of
"noise diffs" between master and XFA as seen in
    https://codereview.chromium.org/1399273003/

These include: blank lines and missed merges:
  3c012fe else-after-returns (partial)
  fb07e28 Tidy up CPDFDOC_Environment (partial, consts missing).
  624b166 Allow FPDFBookmark_GetFirstChild to return the top level bookmark
