A long long time ago, in a galaxy^W^W^W we used DDE kit to ease the
porting of purely C based drivers. By now it became clear, that we
do not gain that much by following this approach. DDE kit contains
much generic functionality, which is not used or rather not needed
by most ported drivers. Hence, we implement a slim C wrapper on top
of Genode's C++ APIs, that is especially tailored to the driver.
In addition to removing the dependency on DDE kit, the iPXE driver
now uses the server framework and the newly introduced signal based
IRQ handling.
Issue #1456.
