Summary:                    [patch] I could not find an easy way to access 
DAHDI channel and span number from the dialplan.
Description: 
  I could not find an easy way to access from the dialplan the span and the
PRI channel being used by an Asterisk channel. As a quick solution I
patched chan_dahdi so that it will populate - if applicable - two
variables:

  PRI_CHANNEL: the PRI channel number
  PRI_SPAN: the PRI span number

  These variables can then be used in the dialplan. The patch it's pretty
simple, even if I don't know how much it could be needed by others.

Attached issue17683_v1.8.patch file.  I started with the
chan_dahdi-channel.patch and changed:
CHANNEL(pri_channel) --> CHANNEL(dahdi_channel)
CHANNEL(pri_span) --> CHANNEL(dahdi_span)
because the value is applicable to chan_dahdi as a whole instead of just
PRI channels.

I added CHANNEL(dahdi_type) so the dialplan can determine what kind of
DAHDI channel it is so CHANNEL(no_media_path) can be used without
generating a warning in mixed DAHDI channel type environments.
