Integrate the Spandsp library for G.722 and G.726 support. Adds support for G.722 and all eight variants of G.726. Note: this also fixes a crash in Qt (buffer overrun, reading too much data) caused by confusion of the larger output buffer (resample_buff) with the smaller input buffer (decode_buff). It was not triggered before because the sample rate was always 8k, but with the addition of the new codecs, a different sample rate became possible (16k). Fix also a crash which occurs when the RTP_STREAM_DEBUG macro is enabled and the VOIP Calls dialog is opened (the begin frame, start_fd, is not yet known and therfore a NULL dereference could occur). Passes testing (plays normally without bad RTP timing errors) with SampleCaptures files: sip-rtp-g722.pcap and sip-rtp-g726.pcap. Tested with cmake (Qt), autotools (Qt and GTK+) with ASAN enabled.
