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.

Note that we don't actually support building mod_spidermonkey for
Debian at the moment.

Note that we don't actually support building mod_managed at this time
for Debian.

This only works on Linux.

If we receive SIGTERM or SIGILL we should propagate the signal to the
child FS process.  As FS normally handles these signals, we need to
restore the handler before we refork.

FS may also add a handler for SIGCHLD; we need the default action
here instead for the parent.

When FS is given the -reincarnate flag, FS will be automatically
restarted after any uncontrolled exit.
