2018-04-04[Merge M66] Handle inserting negative values without a selectionDan Sinclair
When handling the AFNumber_Keystroke callback, if the changed value is negative and there is no selection, we'd incorrectly error out thinking we were inserting before the negative sign. This CL checks if the selection string is empty before erroring out.

The keyword list in the formcalc lexer is only used to match identifiers. We don't need to store the non-identifier tokens in the list, so they're removed. The hash is removed and the list is compared by string instead. The token names have been moved to DEBUG so they won't be included in Release builds.

This reverts commit 2388506a1ba13481463033b414f46c1b8864519e. Reason for revert: Fixed the fallthroughs in XFA and some others. After the following CLs, I'm pretty confident the errors are caught in the PDFium bots rather than on Chromium waterfall: https://pdfium-review.googlesource.com/c/pdfium/+/27010 Roll DEPS for clang to a695c30c. https://pdfium-review.googlesource.com/c/pdfium/+/26950 Fix fallthroughs in XFA code. https://pdfium-review.googlesource.com/c/pdfium/+/27050 Fix more fallthroughs before reenabling -Wimplicit-fallthrough.

2018-02-16Correct mapping text to characters for characters missing from fontRyan Harrison
When parsing text streams there is an internal character list that is generated of all the characters in the stream. Additionally a text string is generated that is exposed via the public API. This string will have all of the printing, i.e. non-control characters, in it. For characters that are not in the font of the stream the unicode, but printable, the character 0xFFFE is used in the text to indicate a missing character. This a non-printing character to indicate non-unicode. The internal character list gets a Unicode value 0x0 when there isn't a glyph in the font for it and the original character code is preserved. This means that when generating the mapping between text string and character list, the code is mistakenly thinking that the unprintable character was not present in the text string. I have changed the check in the mapping generation code to correctly account for this. Additional investigation is needed to determine if inserting 0xFFFE in the text is the correct behaviour. This patch resolves an issue where the find highlights in Chrome for a PDF would be offset when there are unprintable characters in a stream.
