2017-08-29Make some CPDF_StreamContentParser methods static.Lei Zhang
For methods that are only exposed for testing. Once they are static, there is no need for dummy CPDF_StreamContentParser constructor calls in the unit tests. Adjust the CPDF_StreamContentParser constructor now that one of the parameters can no longer be a nullptr.

The various string classes, CFX_ByteString, CFX_ByteStringC, CFX_WideString, and CFX_WideStringC, have many conditionals that are effectively determining if a value is a valid index or length. This CL refactors the logic into one place per class, so it only needs to be changed once if its behaviour needs to change. It also make the some of the methods stricter on the inputs they will accept.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.
