2018-05-14Use internal wcstof instead of system wcstod in formcalc lexerDan Sinclair
This CL switches the usage of wcstod to use the FXSYS_wcstof to determine if a given string is a valid floating point number. Using the internal method makes linux slightly slower (10's of ms) makes mac a lot faster 900ms to 60ms for the test case in the bug. The FXSYS_wcstof method has been extended to handle the parsing of float exponents. Unittests were added for FXSYS_wcstof.

2018-05-09Do not build TIFF when codec is disabledRyan Harrison
Currently all of the TIFF related code is being built when support for the codec is disabled, it just isn't being utilized. Depending on the settings being used, this unneeded code may or may not get stripped during linking. This CL explicitly turns off building the TIFF codec code if support for TIFF is turned off. It also fixes cases in the code base where tif was being used instead of tiff.
