- add b64, clearmode, cv (broken), dahdi_codec, dialplan_directory,
event_test, event_zmq, pocketsphinx, posix_timer, random, vmd and yuv.
- some of the new modules require extra sources, so add a download
routine for those so we can verify the checksums and prevent FreeSWITCH
build system to download them on its own.
- add two patches to fix some issues with the new modules.
