Jingle Audio: Update codecs (Patch)
This patch enables the Speex codec without promoting it to the preferred default codec. speex/16000 was hard coded as the preferred codec, which effectively prevented the use of the Opus codec between Gajim clients (since the introduction of Opus in farstream). speex/32000 is also added.
Codecs are offered in this order now:
all other codecs like L16 (16bit, 44.1khz, 1.4Mb/s), MPA (MPEG-2), MP3, or patented Siren are disabled now.
