sysfs: new driver attribute: master_span

Browse Source 
* This changeset adds master_span as an attribute of the span's driver:
  /sys/bus/dahdi_spans/drivers/generic_lowlevel/master_span
* This is mainly used for debugging.
* Reading from it the master span number (or 0 if there is no master
  span).
* Writing a number to it, force specified span to be master
* Existing Alternatives:
  - grep "MASTER" from /proc/dahdi/*
  - cat /sys/bus/dahdi_spans/devices/span-*/is_sync_master
