Span.pm: Process the /proc/dahdi/<x> files atomically.
It is possible that the contents of the proc files can change while the perl modules are in the processing of processing them. Specifically, if lsdahdi is called on boot before the channels are configured, the channel will be "probed" to determine if it's an FXO or FXS channel and that can result in the output of proc changing. When the size of proc changes, the script can get confused about where the beginning of the next line is. This patch reads in the proc file completely into memory first, and then starts processing each of the lines. This resolves the "Unrecognized garbage 'INACTIVE)' in -" that is displayed on boot with the recent trunk of DAHDI.
