span_sysfs_{create,remove}

Browse Source 
* Separate out device generation in dahdi_[un]register to separate
  functions.
* As we don't keep anywhere the information of whether or not
* there's
  an existing device node for a channel, I abuse an unused flag:
  DAHDI_FLAGBIT_DEVFILE (25), to mark if the channel has a sysfs node.

DAHDI_FLAGBIT_DEVFILE is expected to be replaced later on with a proper
pointer to the device (or embedding of the device). I prefer a simple
flag for now as it does not break ABI.
