Separate agg-authored code from fx-authored code.chromium/2439chromium/2438chromium/2437chromium/2436chromium/2435
Creates a separate library so we can apply less-strict warnings to the code we can't change from upstream vs. the code we can change, reducing noise in the standalone build. Remove needless foo.{cpp,h} files that merely perform indirection via #include "some_other_path/foo.{cpp,h}". BUG=pdfium:166 R=brucedawson@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/1152743007.
