There is no reason to check if the idle thread is a cooperative thread
before invoking k_yield(); it is safe to unconditionally invoke it every
iteration.
Rationale: If the idle thread is cooperative, k_yield() must be invoked
to allow a new thread to get scheduled to run. If the idle thread is
preemptive, then k_yield() effectively becomes a no-op.

Most apps run fine with static k_timer objects. Don't pay the cost
for the timer pool if no one asks for it.
Also turn off the allocate/free API in the header if it can't possibly
work at runtime as it's an obviously-detectable error that would
otherwise be visible only at runtime.

This context must be set for TX buffers, and there's no better place to
set it than at the allocation time. If not set, it may end up NULL,
causing adverse effects (one seen by few parties is dereferencing random
memory locations to get (random again) MSS values). For RX buffers, uIP
context is set elsewhere too, but anyway, common sense says that if a
buffer is allocated for network context X, and that context uses uIP
connection Y, the a buffer should be just cross-linked with Y during
allocation time, not somewhere later.

During USB device reset, the controller must have its device address
cleared (set to 0). This is not really taken into account by most host
side stacks, which is the reason why this bug didn't show up before.
It was found when we were trying to run the USB20CV [1] compliance test
suite on Windows.
Without this fix the device doesn't show up on the targets list, which
means device enumeration failed. With this patch in place the bug is
fixed and the device gets listed.
Tested with the CDC ACM sample application.
