apart.

-Decode base64-encoded string `s`, `len` into the destination `dst`.
-Destination has to have enough space to hold decoded buffer.
-Decoding stops either when all string has been decoded, or invalid
-character appeared.
-Destination is '\0'-terminated.
-Return number of decoded characters. On success, that should be equal to
-`len`. On error (invalid character) the return value is smaller then `len`.
