to devlist.c
* devlist.c, devlist.h: Another step towards
dynamically loadable devices. The first_device() and
next_device() functions abstract away the actual
implementation of the devices list. Currently it is a fixed
length array, when we start supporting dynamically loaded devices,
this is no longer true.
* test_devlist.c: Checks the implementation of first_device()
and next_device().
* Makefile.am, .cvsignore: Updates for new files.
