fecb03ecf8 bitarray: Fix mismatch checking when matching regions
We are currently reporting the wrong mismatching bits in in-between
bundles. Fix this and extend the test to cover the wrong case.

77e5426c5f lib: bitarray: Remove redundant code
Remove statement probably left after rebase. ret should be 0 or
error codes, described in docs, and it is rewritten 4 lines below.

8dbe58907d os: bitarray.c: Address -Wextra warnings
Changed incrementing `for` loop counters to `size_t` from `int` to
eliminate warning, "warning: comparison of integer expressions of
different signedness: 'uint32_t' {aka 'unsigned int'} and 'int'
[-Wsign-compare]"

cbd31d720b lib: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all lib code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

05e16411fb os/lib: change all NULL checking in bitarray.c to asserts
Some problems, as passing NULL when a context in expected,
always reflect to bugs. Such problems cannot be handled
in runtime. So the desired action is system panic.

6c6a16d3b9 lib: bitarray: sys_bitarray_test_and_set_region added
a method to check and set/clear a chosen region in a bitmap
if not previously set/cleared in a single atomic operation.
Useful for keeping track of resources usage, like memory banks

660d30e870 sys: bitarray: remove set but unused variable
The mismatch_mask in match_region() is set but never actually
being used. So remove it as Clang complains.

ff407fb922 sys: introduce bit arrays
This introduces bit arrays as a new data type. This is different
than sys_bitfield as it is working on raw arrays of 32-bit
data. The bit arrays encode additional data inside the struct
to avoid going beyond the declared number of bits, and also
provides locking.
