Effectively the only way to recover from errors in the communication
with pcid is by restarting the driver from scratch possibly after
restarting pcid. As such moving the aborts from individual drivers to
pcid_interface simplifies drivers while at the same time allowing nicer
error messages.
The daemon responsible for the boot log must never ever block to avoid
deadlocks, but doing so while still accepting keyboard input is
non-trivial. This commit splits the boot log out from fbcond into a
separate daemon to make this a lot easier to implement. This will also
allow making fbcond blocking again, which will simplify some things.
