4c1f1edf21 test/kernel/mbox: Drop needless _1cpu_ from test cases
This test is already running with CONFIG_MP_NUM_CPUS=1.  All those
1cpu declarations are needless.  And some of them (like the init
tests) have side effects that make it difficult to do things like
"filter for only MP cases".

(Indeed, this is a heavily MP-unsafe test; almost all cases written to
rely on ordering between a parent thread and its child.  And that's
doubly so for COHERENE platforms because lots and lots of the test
objects are on stacks.  MP_NUM_CPUS=1 is definitely the right thing
here.)

987658dcee tests/kernel: Fill allocation robustly for mpool heap backend
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.

32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

d1200d2155 tests: Never disable SMP
Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.

Turn it on pervasively.  Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests
that can be independently run in an otherwise SMP environment, and via
setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

6311766d9a pointer-type args: cast appropriately to be 64-bit compatible
Using void pointers as universal arguments is widely used. However, when
compiling a 64-bit target, the compiler doesn't like when an int is
converted to a pointer and vice versa despite the presence of a cast.
This is due to a width mismatch between ints (32 bits) and pointers
(64 bits). The trick is to cast to a widening integer type such as
intptr_t and then cast to
void*.

When appropriate, the INT_TO_POINTER macro is used instead of this
double cast to make things clearer. The converse with POINTER_TO_INT
is also done which also serves as good code annotations.

While at it, remove unneeded casts to specific pointer types from void*
in the vicinity, and move to typed variable upon function entry to make
the code cleaner.

0c80ee0831 tests/kernel: Bump stack sizes for a few tests on qemu_x86
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.

Added new test cases to increase the impact of the test cases.
The following are the brief description of the testcases:
1. Incorrect receiver address.
2. Incorrect transmit address.
3. Mbox_get timeout occurs when not able to retrive a msg.
4. Discard a msg by passing an invalid pool id.
5. Msg id mismatch between the receiver and transmitter.
6. Copy tx buffer to a new block in the pool.
7. Copy a big tx buffer to a block in the pool but no block
   can fit it.
8. Dispose a msg as soon as it is read.
9. Free tx pool when we read the msg.
10. A Asynchronous put unblocks a waiting get.
11. A Asynchronous put sends a wrong address to a waiting get.
12. Multiple Asynchronous put populates the msg_q and mbox_get
    retrives it.
13. Multiple waiting mbox_get and each put unblocks it one at a time.

73cb9586ce k_mem_pool: Complete rework
This patch amounts to a mostly complete rewrite of the k_mem_pool
allocator, which had been the source of historical complaints vs. the
one easily available in newlib.  The basic design of the allocator is
unchanged (it's still a 4-way buddy allocator), but the implementation
has made different choices throughout.  Major changes:

Space efficiency: The old implementation required ~2.66 bytes per
"smallest block" in overhead, plus 16 bytes per log4 "level" of the
allocation tree, plus a global tracking struct of 32 bytes and a very
surprising 12 byte overhead (in struct k_mem_block) per active
allocation on top of the returned data pointer.  This new allocator
uses a simple bit array as the only per-block storage and places the
free list into the freed blocks themselves, requiring only ~1.33 bits
per smallest block, 12 bytes per level, 32 byte globally and only 4
bytes of per-allocation bookeeping.  And it puts more of the generated
tree into BSS, slightly reducing binary sizes for non-trivial pool
sizes (even as the code size itself has increased a tiny bit).

IRQ safe: atomic operations on the store have been cut down to be at
most "4 bit sets and dlist operations" (i.e. a few dozen
instructions), reducing latency significantly and allowing us to lock
against interrupts cleanly from all APIs.  Allocations and frees can
be done from ISRs now without limitation (well, obviously you can't
sleep, so "timeout" must be K_NO_WAIT).

Deterministic performance: there is no more "defragmentation" step
that must be manually managed.  Block coalescing is done synchronously
at free time and takes constant time (strictly log4(num_levels)), as
the detection of four free "partner bits" is just a simple shift and
mask operation.

Cleaner behavior with odd sizes.  The old code assumed that the
specified maximum size would be a power of four multiple of the
minimum size, making use of non-standard buffer sizes problematic.
This implementation re-aligns the sub-blocks at each level and can
handle situations wehre alignment restrictions mean fewer than 4x will
be available.  If you want precise layout control, you can still
specify the sizes rigorously.  It just doesn't break if you don't.

More portable: the original implementation made use of GNU assembler
macros embedded inline within C __asm__ statements.  Not all
toolchains are actually backed by a GNU assembler even when the
support the GNU assembly syntax.  This is pure C, albeit with some
hairy macros to expand the compile-time-computed values.

Related changes that had to be rolled into this patch for bisectability:

* The new allocator has a firm minimum block size of 8 bytes (to store
  the dlist_node_t).  It will "work" with smaller requested min_size
  values, but obviously makes no firm promises about layout or how
  many will be available.  Unfortunately many of the tests were
  written with very small 4-byte minimum sizes and to assume exactly
  how many they could allocate.  Bump the sizes to match the allocator
  minimum.

* The mbox and pipes API made use of the internals of k_mem_block and
  had to be ported to the new scheme.  Blocks no longer store a
  backpointer to the pool that allocated them (it's an integer ID in a
  bitfield) , so if you want to "nullify" them you have to use the
  data pointer.

* test_mbox_api had a bug were it was prematurely freeing k_mem_blocks
  that it sent through the mailbox.  This worked in the old allocator
  because the memory wouldn't be touched when freed, but now we stuff
  list pointers in there and the bug was exposed.

* Remove test_mpool_options: the options (related to defragmentation
  behavior) tested no longer exist.
