Summary:                    handle DAHDI_EVENT_REMOVED on a D-Channel
Description: 
When a DAHDI device is removed at run-time it sends the event
DAHDI_EVENT_REMOVED on each channel. This is intended to signal the
userspace program to close the respective file handle, as the driver of the
device will need all of them closed to properly clean-up.

This event has long since been handled in chan_dahdi (chan_zap at the
time). However the event that is sent on a D-Channel of a "PRI" (ISDN) span
simply gets ignored.

This code adds handling for closing the file descriptor (and shutting down
the span, while we're at it). It also adds a CLI command to help test it.
