Matt Caswell 3fd5970035 Add support for the SRP base64 alphabet ... Historically we used to implement standalone base64 code for SRP. This was replaced by commit 3d3f21aa with the standard base64 processing code. However, the SRP base64 code was designed to be compatible with other SRP libraries (notably libsrp, but also others) that use a variant of standard base64. Specifically a different alphabet is used and no padding '=' characters are used. Instead 0 padding is added to the front of the string. By changing to standard base64 we change the behaviour of the API which may impact interoperability. It also means that SRP verifier files created prior to 1.1.1 would not be readable in 1.1.1 and vice versa. Instead we expand our standard base64 processing with the capability to be able to read and generate the SRP base64 variant.
