257d9d45ba kernel: sys_heap: stats: save heap pointers to an array during init
To request heap statistics, a pointer to a heap structure is required.
This is straightforward for a user-defined heap. However, such a pointer
is not known for heaps created by other components or libraries, like
libc. Therefore, it is not possible to calculate the total heap memory.

The proposed solution is to use an array of pointers, which is filled in
on every sys_heap_init() call. One can then iterate through it to sum up
the total memory allocated for all heaps.

The array size is configurable. The default array size is zero,
which means the feature is disabled. Any other integer greater then zero
defines the array size and enables the feature.

A list of pointers instead of an array could be another approach,
but it requeres a heap, which is not always available.

388f82f6b3 samples/basic: Switch from native_posix to native_sim
In the docs replace the references to native_posix with native_sim.
And switch the default test platform to native_sim from native_posix.

59e4c5aed0 samples: fully migrate basic samples to the new Sphinx extension
- Updated basic samples READMEs to use the new zephyr:code-sample::
  directive. Dropped "-sample" suffix that's not required anymore now
  that samples have their own namespace.
- Updated all references to the samples to use the :zephyr:code-sample:
  role. Checked and updated the wording of said references to account
  for the fact that samples should not have "... sample" in their name
  anymore.

88a3620ff9 samples/basic: print_sys_memory_stats() removed from hash_map, static
Remove print_sys_memory_stats() from hash_map example as it is not used
there at all. For sys_heap make this a static function.

93b63df762 samples, tests: convert string-based twister lists to YAML lists
Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.

0b90fd5adf samples, tests, boards: Switch main return type from void to int
As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.

Most of these changes were automated using coccinelle with the following
script:

@@
@@
- void
+ int
main(...) {
	...
-	return;
+	return 0;
	...
}

Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.
