"It's a Trap!" -- Admiral Ackbar
When moving to the BSD-socket APIs, the original thread running LwM2M
periodic services such as observes and lifetime updates, was replaced
with a re-occuring workqueue job. To save the overhead of creating a
new thread, I used the system workqueue for these jobs.
This was a mistake. If these jobs hit a semaphore or wait for some
reason, it cannot be prempted due to the priority of the system work
queue.
Let's instead add this service handling to the thread that we already
use for polling sockets. This also removes a configuration issue where
the system workqueue stack size needed to be increased. This can now
be adjusted via the LWM2M_ENGINE_STACK_SIZE knob.
Directly fixes semaphore usage in the socket-based DNS code.
This was introduced as a bugfix for non-responsive DNS server hanging
the Zephyr device forever. However, this probably fixes randomly
seeming hangs on the device.

As this step takes a nontrivial amount of time, add an

When calling bt_unpair() the keys were removed from flash, however a
pointer was left to the invalidated keys in case there was an existing
connection. This would then lead to a bogus entry being stored in
flash for a zero-address peer device. Fix this issue by clearing the
conn->le.keys pointer in the bt_unpair() function.

Casting the rb_data character array to a u32_t can result
in an unaligned u32_t * pointer being passed to
ring_buf_item_put(), since rb_data is only byte-aligned.
Our Altera Max10 CPU build is not configured to detect
unaligned memory access and throw an exception, it is
instead rounding down the memory address
of the data pointer to the nearest 4-byte value, causing
the wrong data to be copied into the ring buffer.
It appears that in the C standard this is considered
Undefined Behavior so the approach this patch takes is
to fix the test, by ensuring that rb_data is aligned to
u32_t.

The NSIM emulator has severe performance issues when
the MPU registers are reprogrammed on context switch.
Disable runtime reprogramming of the MPU for these
platforms on these two tests, which have a lot of context
switch thrashing. This is done by ensuring userspace
and hardware stack overflow detection via guard areas
is disabled.
I have assurances from the ARC team that the tests run fine
on real hardware and this is an emulation issue.
For 1.15, this will be completely resolved by optimizing
MPU region gap-filling to not take place during context
switch time, which will drastically reduce the number of
MPU registers poked during context switch on nsim_sem.
Meanwhile, for 1.14 we ensure that no runtime reprogramming
of the MPU is done for these tests.

Kconfig requires posix style path when sourcing other files.
As abspath in python will use native host style, i.e. backslash '\' in
windows this will cause invalid paths in Kconfig generated file and
thus the file will never be loaded.
This commit uses PurePath to convert the path to posix style, ensuring
Kconfig can load the modules.

A transport may receive multiple bytes of data between shell_thread
wakeups, but state_collect is only called once per wakeup. So it must
process all data, and only return when all data from the transport has
been consumed. This is mostly handled correctly, but there were two
places where state_collect would return early instead.

Unlike CONFIG_HW_STACK_PROTECTION, which greatly helps
expose stack overflows in test code, activating
userspace without putting threads in user mode is of
very limited value.
Now CONFIG_TEST_USERSPACE is off by default. Any test
which puts threads in user mode will need to set
CONFIG_TEST_USERSPACE.
This should greatly increase sanitycheck build times
as there is non-trivial build time overhead to
enabling this feature. This also allows some tests
which failed the build on RAM-constrained platforms
to compile properly.
tests/drivers/build_all is a special case; it doesn't
put threads in user mode, but we want to ensure all
the syscall handlers compile properly.
