[issue17618] base85 encoding

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I'm not very interesting in working on this (but analyzing and optimizing made fun to me). You Antoine as originator definitely are interested. So make decision about interface which you need and finish the work using proposed patches as a basis. I would made a review.

I'm a little doubt about appropriateness base85 codec in the base64 module ("This module provides data encoding and decoding as specified in RFC 3548."). Base85 is not standard. But I don't see better place for it. At least the description of the base64 module should be corrected.

I suggest first resolve issue16995. Perhaps it will get suggestions about base85 interface.
