2017-08-16Move some CFDE_TxtEdt* methods to the headerschromium/3188Dan Sinclair
This CL moves several methods from the CFDE_TxtEdt* classes from the .cpp to .h files. As well, the GetCaretRect method is updated to return the rect instead of using an out param.

2017-08-16Add parse depth limit to FormCalc parserRyan Harrison
Due to the recursive nature of the FormCalc parser, deeply nested expressions can lead to memory being exhausted. This check is being added to have the parser exit early instead of running out of memory. This should reduce the number of false positives about addressing issues being found by fuzzers.

2017-08-16Fixed the return values of FPDFAnnot_Get{Rect|AttachmentPoints}Jane Liu
Currently, FPDFAnnot_Get{Rect|AttachmentPoints} would return BBox if the annotation's appearance stream is defined, which does not make much sense to the user since BBox is defined in the form space; upon rendering, the annotation's position in the device space is solely defined by its rectangle. This CL removes references to BBox in FPDFAnnot_Get{Rect| AttachmentPoints}; instead, they will only return rectangle or quadpoints as requested. The embedder test is also modified to reflect this change, and also to demonstrate that an annotation's position is changed only if its rectangle is changed.

The one for from16-to-8-overflow.patch was deleted as it was already upstream. Some patches did not apply cleanly so their .patch files were modified. - Patch 26: as I just moved files directly, unsupported characters were moved in unchanged, so I had to fix all of them: e with tilde and other characters were replaced to allow compilation on Windows. - Patch 27: Went over the code and re-applied changes that included comments clearly indicating this was Foxit.
