CURLOPT_BUFFERSIZE: support enlarging receive buffer
Replace use of fixed macro BUFSIZE to define the size of the receive buffer. Reappropriate CURLOPT_BUFFERSIZE to include enlarging receive buffer size. Upon setting, resize buffer if larger than the current default size up to a MAX_BUFSIZE (512KB). This can benefit protocols like SFTP. Closes #1222
