The selection of the Cortex M systick driver to be used as a system
clock driver is controlled by CONFIG_CORTEX_M_SYSTICK.
To replace it by another driver CONFIG_CORTEX_M_SYSTICK must be set
to 'n'. Unfortunately this also controls the interrupt vector for
the systick interrupt. It is now routed to z_arm_exc_spurious.

This patch introduces two major changes to the directed advertising
feature of the bluetooth host.
Deprecating the bt_conn_create_slave_le, and removing
bt_conn_le_create_slave which has never been released. This behaviour
has now been moved by to providing the peer direct address into the
advertising parameters.
Introducing directed advertising support for nonconnectable
directed extended advertising, both scannable and non-scannable.
A bug was also fixed in the the directed-adv command in the shell
when the argument "low" was given. The advertiseng parameter pointer
declared with BT_LE_ADV_CONN_DIR_LOW_DUTY was declared in a scope that
was no longer valid when it was used to start the advertiser.

These five tests (mbox_api, mheap_api_concept, msgq_api, pipe_api and
queue) all had test cases where they needed a mem_pool allocation to
FAIL. And they are all written to assume the behavior of the original
allocator and not the more general k_heap code, which actually
succeeds in a bunch of these cases.
* Even a very small heap saves enough metadata memory for the very
small minimum block size, and this can be re-used as an allocation.
So you can't assume a small heap is full.
* Calculating the number of blocks based on "num_blocks * max size /
minimum size" and allocating them does not fill the heap, because
the conservative metadata reservation leaves some space left over.
So these have all been modified to "fill" a heap by iteratively
allocating until failure.
Also, this fixes a benign overrun bug in mbox. The test code would
insert a "big" message by reading past the end of the small message
buffer. This didn't fail because it happened to be part of an array
of messages and the other ones defined contained the memory read. But
still.

The original k_mem_pool tests were a mix of code that tests routine
allocator behavior, the synchronization layer above that, and a
significant amount of code that made low-level assumptions about the
specific memory layout of the original allocator, which doesn't run
out of memory in exactly the same way.
Adjust the expectations as needed for the backend. A few test cases
were skipped if they were too specific. Most have been generalized
(for example, iteratively allocating to use up all memory instead of
assuming that it will be empty after N allocations).

This adds a k_heap data structure, a synchronized wrapper around a

implementation to k_mem_pool() with somewhat better efficiency and
performance and more conventional (and convenient) behavior.

Almost all of the k_mem_pool API is implemented in terms of three
lower level primitives: K_MEM_POOL_DEFINE(), k_mem_pool_alloc() and
k_mem_pool_free_id(). These are themselves implemented on top of the
lower level sys_mem_pool abstraction.
Make this layering explicit by splitting the low level out into its
own files: mempool_sys.c/h.

Use the white box validation and test rig added as part of the
sys_heap work. Add a layer that puts hashed cookies into the blocks
to detect corruption, check the validity state after every operation,
and enumerate a few different usage patterns:
+ Small heap, "real world" allocation where the heap is about half
full and most allocations succeed.
+ Small heap, "fragmentation runaway" scenario where most allocations
start failing, but the heap must remain consistent.
+ Big heap. We can't test this with the same exhaustive coverage
(many re/allocations for every byte of storage) for performance
reasons, but we do what we can.

The existing mem_pool implementation has been an endless source of
frustration. It's had alignment bugs, it's had racy behavior. It's
never been particularly fast. It's outrageously complicated to
configure statically. And while its fragmentation resistance and
overhead on small blocks is good, it's space efficiencey has always
been very poor due to the four-way buddy scheme.
This patch introduces sys_heap. It's a more or less conventional
segregated fit allocator with power-of-two buckets. It doesn't expose
its level structure to the user at all, simply taking an arbitrarily
aligned pointer to memory. It stores all metadata inside the heap
region. It allocates and frees by simple pointer and not block ID.
Static initialization is trivial, and runtime initialization is only a
few cycles to format and add one block to a list header.
It has excellent space efficiency. Chunks can be split arbitrarily in
8 byte units. Overhead is only four bytes per allocated chunk (eight
bytes for heaps >256kb or on 64 bit systems), plus a log2-sized array
of 2-word bucket headers. No coarse alignment restrictions on blocks,
they can be split and merged (in units of 8 bytes) arbitrarily.
It has good fragmentation resistance. Freed blocks are always
immediately merged with adjacent free blocks. Allocations are
attempted from a sample of the smallest bucket that might fit, falling
back rapidly to the smallest block guaranteed to fit. Split memory
remaining in the chunk is always returned immediately to the heap for
other allocation.
It has excellent performance with firmly bounded runtime. All
operations are constant time (though there is a search of the smallest
bucket that has a compile-time-configurable upper bound, setting this
to extreme values results in an effectively linear search of the
list), objectively fast (about a hundred instructions) and amenable to
locked operation. No more need for fragile lock relaxation trickery.
It also contains an extensive validation and stress test framework,
something that was sorely lacking in the previous implementation.
Note that sys_heap is not a compatible API with sys_mem_pool and
k_mem_pool. Partial wrappers for those (now-) legacy APIs will appear
later and a deprecation strategy needs to be chosen.

I personally don't find it very useful to have to maintain prj.conf
and prj_spi.conf for this sample. The information we need to make
this application "just work" with regards to the bus is available in
the devicetree, and Kconfig can now access it using
dt_compat_on_bus().
Do so, enabling I2C and SPI appropriately when a sensor of the right
type is on either of those buses.
If no sensors are enabled, the user gets the build-time error message
in main.c about no devices being found.
This approach is prone to the "stuck symbol" Kconfig problem covered
in our documentation, so a pristine build is necessary to change the
default settings from a previous build.
