* devices.h (lives_in_dev): New field.

Browse Source 
(dev_on_fs): Set bit size.
(is_dev_resident): Define new method.
* devices.in: Use different method for labelling requested name for dev
storage: prefix it with a ='.  Use an actual ':' to denote an internal device.
(exists_console): Avoid repeated test.
(exists_ntdev_silent): Rename from the less-descriptive exists_ntdevs.
(dev_dev_storage): Delete unneeded define.
* gendevices: Add a flag to each line denoting whether the device lives in /dev
space.
(generate): Handle special ":" case here for internal devices.  Parse
=something_dev as requiring a storage location.  Tack the rest of the line back
onto the reformulated "$rest".
* devices.cc: Regenerate.
