* Called by SANE to find out about supported devices.

* From the SANE spec:
* This function can be used to query the list of devices that are
* available. If the function executes successfully, it stores a
* pointer to a NULL terminated array of pointers to SANE_Device
* structures in *device_list. The returned list is guaranteed to
* remain unchanged and valid until (a) another call to this function
* is performed or (b) a call to sane_exit() is performed. This
* function can be called repeatedly to detect when new devices become
* available. If argument local_only is true, only local devices are
* returned (devices directly attached to the machine that SANE is
* running on). If it is false, the device list includes all remote
* devices that are accessible to the SANE library.
*
* SANE does not require that this function is called before a
* sane_open() call is performed. A device name may be specified
* explicitly by a user which would make it unnecessary and
* undesirable to call this function first.
*
* Read the config file, find scanners with help from sanei_*
* store in global device structs
