2017-10-02Replace GetWord_LSBFirst with FXWORD_GET_LSBFIRSTchromium/3231Ryan Harrison
The existing implementation of a LSB first word method was incorrect, in addition it was implemented to the BMP code, but also used in the GIF code. Thus is should be moved to a common location. Also added in an implementation for FXWORD_GET_MSBFIRST, since the GIF code will need this.

This ports https://chromium-review.googlesource.com/c/chromium/src/+/599127 from Chromium to PDFium. Because VC++ does not have format-string checking for user-defined functions during normal compiles, because clang-cl had its format-string checking disabled, because some files are only compiled on Windows, and because VC++'s /analyze doesn't build all targets, and because VC++'s format-string checking is more lenient than clang's... 50 warnings about format-string mismatches crept in to Chromium's build. Seven of these were somewhat serious, with four being wchar_t*/char* mismatches because of base::FilePath and the other three being size_t/%d mismatches. Now that all of the mismatches are corrected this change enables PRINTF_FORMAT checking with clang-cl so that these bugs never return.
