Add pf_invalid arg to std::string DecodeBase{32,64}

Browse source 
Add support for the optional "pf_invalid" out parameter (which allows the caller
to detect decoding failures) to the std::string versions of DecodeBase32 and
DecodeBase64. The char* versions already have this feature.

Also, rename all uses of pfInvalid to pf_invalid to match style guidelines.
