We now create a special IA hardware task for handling
double faults. This has a known good stack so that if
the kernel tries to push stack data onto an unmapped page,
we don't triple-fault and reset the system.

We will need this for stack memory protection scenarios
where a writable GDT with Task State Segment descriptors
will be used. The addresses of the TSS segments cannot be
put in the GDT via preprocessor magic due to architecture
requirments that the address be split up into different
fields in the segment descriptor.

This has one use-case: configuring the double-fault #DF
exception handler to do an IA task switch to a special
IA task with a known good stack, such that we can dump
diagnostic information and then panic.
Will be used for stack overflow detection in kernel mode,
as otherwise the CPU will triple-fault and reset.

This is one less host tool we have to compile for every build,
and makes the build tools more portable across host OSes.
The code is also much simpler to maintain.

This enables the MMU-based stack protection feature,
which will cause a fatal error if a thread overflows
its stack in kernel mode, at a nontrivial cost in memory
(4K per thread).

Zephyr supports the flash and debug targets via per-board information
in Makefile.board files.
It is sometimes convenient to know this information when inspecting
the build artifacts or doing exotic builds, so include it in the file
generated by outputexports. The information in Makefile.board provides
what is needed.
Therefore, ensure that Makefile.board, when present, is included by
the generated Makefile.export. This gives users of Makefile.export
access to variables like FLASH_SCRIPT, PYOCD_TARGET, etc. (These users
need to cope with these variables being undefined if not given in
Makefile.board, or if Makefile.board does not exist for a target.)
While we're here, don't export INSTALLKERNEL. That's Linux-specific
and otherwise unused; the Zephyr equivalent is FLASH_SCRIPT and its
associated variables.

Instead of only running net tests in qemu_x86, enable those
tests in all suitable platforms. The tests are disabled for
bbc_microbit as that platform does not have enough memory.
The tests/net/arp and tests/net/ieee802154/l2 are disabled
for qemu_xtensa as the qemu crashed when running the tests.
For tests/net/all there was a weird build error for qemu_xtensa
so that test is also disabled for that platform.
Increased the trickle timeout to 3 secs in tests/net/trickle as
occacionally there was timeout error in qemu_cortex_m3 when the
test was run.

reserved for use by the application.
This follows the pattern established in f58b36a ("dts: frdm_k64f: make
application state partition a reserved area"), and fixes an error
introduced in 9f7f83d2 ("dts: 96b_nitrogen: add flash partitions"),
