344bfbb71c zephyr: Fix NLR segfault in minimal build. 
Requires inclusion of zephyr.h to properly detect that we're building for
Zephyr.

29dd92c82a zephyr/Makefile: Rework to use modern, official build integration. 
Build happens in 3 stages:

1. Zephyr config header and make vars are generated from prj.conf.
2. libmicropython is built using them.
3. Zephyr is built and final link happens.

dbb2aea428 zephyr/prj_base.conf: Disable legacy kernel compatibility. 
This keeps dependency on mdef, sysgen and other stuff which complicates
build integration.

40e541063f zephyr: Move "minimal" configuration building to a separate wrapper script. 
Minimal config can be now build with:

./make-minimal BOARD=...

This is required because of Makefile.exports magic, which in its turn depends
on PROJ_CONF to be set correctly at the beginning of Makefile parsing at all
times. Instead of adding more and more workarounds for that, it's better to
just move minimal support to a separate wrapper.

Also, remove Zephyr 1.5 era cruft from Makefile, and add support for Zephyr's
"run" target which supercedes older "qemu" target in upstream.

736a8a8ac7 zephyr: Make sure that generated prj.conf is updated only on content changes. 
This is a typical problem with make: we want to trigger rebuilds only
if file actually changed, not if its timestamp changed. In this case,
it's aggravated by the fact that prj.conf depends on the value of
BOARD variable, so we need to do some tricks anyway. We still don't
try to detect if just BOARD changed, just try to generate new
prj.conf.tmp every time (quick), but do actual replacement of prj.conf
only if its content changed.

a64a0276b3 zephyr/modzephyr: Add a module for Zephyr-specific things. 
Mostly intended to ease experimentation, no particular plans for APIs
so far (far less their stability), is_preempt_thread() provided is
mostly an example.

40e72e4a5c zephyr: Make sure that correct Zephyr config is used for "minimal" build. 
Overriding CONF_FILE in "minimal" target itself is too late due to include-

following QEMU networking setup instructions,

56a514c193 zephyr/uart_core: Access console UART directly instead of printk() hack. 
This is required to avoid extra level of output "cooking" ("\r\r\n") and
make test infrastructure work. On the other hand, this breaks somewhat
Zephyr console abstraction.

In 1.6, Zephyr switched to "unified kernel" and new API set. Older kernel
API is supported, but marked as deprecated and leads to warnings.

67b6d9d499 zephyr: Initial implementation of machine.Pin. 
The integration with Zephyr is fairly clean but as MicroPython Hardware API
requires pin ID to be a single value, but Zephyr operates GPIO in terms of
ports and pins, not just pins, a "hierarchical" ID is required, using tuple
of (port, pin). Port is a string, effectively a device name of a GPIO port,
per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer
number of pin with the port (supposed to be in range 0-31).

Example of pin initialization:

pin = Pin(("GPIO_1", 21), Pin.OUT)

(an LED on FRDM-K64F's Port B, Pin 21).

There is support for in/out pins and pull up/pull down but currently
there is no interrupt support.

a3519332b6 zephyr: Use board/SoC values for startup banner based on Zephyr config. 
This patch modifies the HW macro definition in order to let micropython
report correctly the BOARD and the SOC on which it is working on.
