/* Simple BASE64 encode/decode functions.
 *
 * As we might encode binary strings, hence we require the length of
 * the incoming plain source. And return the length of what we decoded.
 *
 * The decoding function takes any non-valid char (such as whitespace, \0
 * or anything non A-Z,0-9 as terminal).
 *
 * Plain strings/binary sequences are not assumed '\0' terminated. Encoded
 * strings are neither. But probably should.
