Encode 'length' bytes from the input buffer and store the encoded stream into the output buffer. Return the length of the encoded stream. Note that the output buffer must be allocated by the caller (length * 1.5 should be a safe estimate). If 'mark_end' is true than an extra set of 4 bytes is added to the end of the stream if the input is a multiple of 3 bytes. These bytes are invalid chars and therefore they will stop the decoder thus enabling the caller to decode a stream without actually knowing how much data to expect (if the input is not a multiple of 3 bytes then the extra padding needed to complete the encode 4 bytes will stop the decoding anyway).

Decode bytes from the input buffer and store the decoded stream into the output buffer until 'length' bytes have been decoded. Return the real length of the decoded stream (which should be equal to 'length'). Note that the output buffer must be allocated by the caller. If 'max_input_length' is not null, then it specifies the number of encoded bytes that should be at most read from the input buffer. In that case the 'length' parameter is ignored. This enables the caller to decode a stream without actually knowing how much decoded data to expect (of course, the buffer must be large enough).
