The gphoto2 device database (gp2ddb) was originally intended to
replace the device lists in the camlib code by a device list
maintained in a text file outside of the camlib C code.
This device list file could then be changed without
recompiling camlibs, at the cost of adding a simple gp2ddb
to internal binary representation compiler to libgphoto2.
This would have allowed a user to very easily add a new camera
model to the list of camera models supported by a specific
camlib, as long as that new camera model uses the same
protocol as already supported camera models do.
As the gp2ddb idea has never been developed any further in the
15 yearns since my initial commit from 2006, this idea appears
to be obsolete and can thus be removed from the codebase.
