gems: remove d3m

Browse Source 
D3m is superseded by now. Altough there is no direct replacement
combining various other components is equal to its functionality.

Issue #1456.

# \brief Boot test for the demo device driver manager
# \author Norman Feske
# \date 2012-01-17
#
# This test exercises the auto-probing of the boot medium performed by d3m.
# D3m support booting from both CD-ROM and USB storage. Both options are
# tested via different qemu arguments.
#
#
# Sanity checks
#
# The test does only work for platforms that use qemu to boot. Because the test
# uses x86-specific drivers, it won't execute on other architectures.

D3m stands for demo device driver manager. It is the service responsible for
implementing device-driver policies such as probing for a boot device or
merging user input coming from different input devices (USB HID and PS/2).
The actual device drivers are executed as child processes of d3m. At the
current stage, d3m is primarily geared towards bootable live CD images.
