af798e7b27 Disable uscanner in all kernel configs 
As discussed on current-users@, SANE uses ugen via libusb and not
uscanner, so users are not well served by having uscanner.  Consensus
is that addressing how to adjust permissions for scanners should not
block restoring basic functionionality.

(Compile-tested only, but there are multiple reports of this being the
right approach.)

e2007d759e gcc does not pass floating point options to the assembler 
by default, because it is afraid that the stricter tests
will break userland code. The new binutils is pickier about
this. Gcc 5.x fixes the issue so for now, set explicitly
the assembler soft-float flags when we build the kernel.

9c4cd06355 Introduce softint-based if_input 
This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Additional information including performance numbers can be found
in the thread at tech-kern@ and tech-net@:

Acknowledgment: riastradh@ greatly helped this work.
Thank you very much!
