The directions here anticipate planned improvements to our JIRA bot to
allow issues to be resolved by placing the JIRA directives in the body
of the commit message.

FS-5659 --resolve Add logging for spandsp dtmf detector when dtmf_verbose channel variable is set to true

mod_skinny: initial reg wasn't able to clean up due to missing device name, add new function to clean up given explicit device name, also add more logging

Only use events to update calls when not pulling

The new websocket stuff breaks windows build so please fix, thanks

Avoid ignoring files actually in our tree, and ignore some generated
files that were not being ignored previously.

This file is specifically ignored by our .gitignore.  Brian added this
ignore on 2013-06-06 but neglected to remove the file.  I've now
bulid-tested without the file to be sure that it is indeed generated
correctly and so can be removed safely.

freeswitch.serial is used by ZRTP as a ZID, so it should not be shared
between systems and definitely should not be distributed as a default
value by us.
