The correct fix would be to detect which crypto layer that is in use and
adapt our code to use that instead of blindly assuming gcrypt.

+9.4 Pipelining

+10.1 APOP Authentication
+ Add support for the APOP command rather than using plain text authentication

Add an option that prevents cURL from overwriting existing local files. When

Currently the command line client needs to get url globbing disabled (with
