The pthread mutex changes went in with an adaptation to build with the
new wait queue API, but they did it by using the old dlist hooks
directly through typecasting and union assignment. That... is sort of
the opposite of the intent to having the new API be abstracted. The
pthread code worked, but failed once wait queues (on x86) stopped
being dlists.
Simple fix once I saw the problem, anyway.

These tests had very small stacks, and the rbtree scheduler on
qemu_x86 (which does need a little extra stack room, though not much)
is bumping up against the limit. Increase by ~128 bytes in most
cases. In the case of the mbox_api test, there are other platforms
(which don't use the tree) which are right against the limit already
and will fail to link with a larger stack, so bump it for qemu_x86
only.

This target is already using the rbtree as part of CONFIG_USERSPACE,
so it incurs no code size overhead (actually it's a little smaller)
when using the scalable scheduler and waitq implementations.
The change also gets us test coverage of those choices on a default CI
target.

This replaces the existing scheduler (but not priority handling)
implementation with a somewhat simpler one. Behavior as to thread
selection does not change. New features:
+ Unifies SMP and uniprocessing selection code (with the sole
exception of the "cache" trick not being possible in SMP).
+ The old static multi-queue implementation is gone and has been
replaced with a build-time choice of either a "dumb" list
implementation (faster and significantly smaller for apps with only
a few threads) or a balanced tree queue which scales well to
arbitrary numbers of threads and priority levels. This is
controlled via the CONFIG_SCHED_DUMB kconfig variable.
+ The balanced tree implementation is usable symmetrically for the
wait_q abstraction, fixing a scalability glitch Zephyr had when many
threads were waiting on a single object. This can be selected via
CONFIG_WAITQ_FAST.

The SMP testing missed the case where _Swap() decides to return back
into the _current. Obviously there is no valid switch handle for the
running thread into which we can restore, and everything blows up.
(What happened is that the new scheduler code opened up a spot where
k_thread_priority_set() does a _reschedule() unconditionally and
doens't check to see whether or not it's needed like the old code).
But that isn't incorrect! It's entirely possible that _Swap() may
find that no thread is runnable except _current (due, for example, to
another CPU racing the other thread you expected off to sleep or
something). Don't blow up, check and return a noop.

The scheduler priq implementation was taking advantage of a subtle
behavior of the way the tree presents the order of its arguments (the
node being inserted is always first). But it turns out the tree got
that wrong in one spot.
As this was subtle voodoo to begin with, it should have been
documented first. Similarly add a little code to the test case to
guarantee this in the future.

This constant should be defined in limits.h. Define it in limits.h in
the minimal libc, and use the definition found in newlib's includes.
Values in newlib includes range from 1024 to 4096.
The rationale is that all code should use the same value; having
buffers specified with different sizes will lead to interoperability
and out of bounds array writes.

This patch adds dts support to lps22hb/hts221/vl53l0x
I2C sensors as well as lsm6dsl SPI sensor.
Since some info, like gpio for irq triggering or SPI bus
characteristics, may be provided through dts, they need
to be made optional in the LSM6DSL driver by usage of
macros like HAS_DTS_SPI_PINS or HAS_DTS_SPI_DEVICE.
