Summary
-------

This code adds chan_dahdi the command 'dahdi create channels <range>' (where <range> is a single <n>-<m>) and updates 'dahdi destroy channel' with a similar 'dahdi destroy channels'.

'dahdi create channels' acts as a filter for process_dahdi() and such in DAHDI: it re-parses the whole configuration, but only attempts to create channels in the range.

Right not this patch disables the initial probing at module load time (workaround: run 'dahdi create channels 1-10000' at startup through cli.conf). This is for debugging, mainly and should be removed later on.

This changeg is intended to provide a hook for a script running from udev once a span has been assigned ("registered") / unassigned ("unregistered") for its channels. The udev hook configures the span's channels with dahdi_cfg -S, and can then ask Asterisk to create ethe channels.

See: https://gitorious.org/~tzafrir/asterisk-tools/tzafrirs-dahdi-tools/commits/pinned-spans

This means that a separate DAHDI init script (running before the Asterisk one) would no longer be required. There is no longer a need to run a single command after all DAHDI devices are up.

Testing
-------

Works well with analog devices. Seems to work with ISDN ones as well. Not fully complete, though.


Thanks,
