// Description:
// 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).

// Description:
// 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).
