3a765f4384 lib: os: Add mpsc (multiple producer, single consumer) packet buffer
Added module for storing variable length packets in a ring buffer.
Implementation assumes multiple producing contexts and single consumer.

API provides zero copy functionality with alloc, commit, claim, free
scheme.

Additionally, there are functions optimized for storing single word
packets and packets consisting of a word and a pointer. Buffer can work
in two modes: saturation or overwriting the oldest packets when buffer
has no space to allocate for a new buffer.

7b6a4da206 libc/minimal: assorted fixes to malloc() and friends
- When malloc() is called with a size of 0 we should not set errno
  to ENOMEM as there is no actual allocation failure in that case.
  This duplicates the realloc() behavior.

- Put unlock_ret assignments on separate lines, otherwise gcc complains
  about unused variables when the tests on it are disabled.

- There NULL return added in 952970d6cb are completely pointless.
  First, there is no reason for sys_mutex_unlock() to fail, and even
  if it did, those returns would be blatent memory leaks. Remove them.
  No one should blindly modify code just to make static code
  analysers happy.

- Replace all CHECKIF() by explicit assertion statements to uniformize
  those checks and drop the NULL returns entirely. We can't return
  anything in the free() case, and there are no runtime conditions
  for sys_mutex_lock() to sometimes succeed and sometimes fail anyway.

c26e08a51f lib: os: cbprintf: Add alignment offset to packaging
Added parameter to CBPRINTF_STATIC_PACKAGE which indicates buffer
alignment offset compared to CBPRINTF_PACKAGE_ALIGNMENT. When offset
is set to 0, macro assumes that input buffer is aligned to
CBPRINTF_PACKAGE_ALIGNMENT. When offset is positive, macro assumes
that buffer address is shifted by given number of bytes to
CBPRINTF_PACKAGE_ALIGNMENT alignment.

Extended cbprintf_package to use len argument as alignment offset
indicator when calculating length only (package pointer is null).

Features are not available for xtensa platform which seems to
require 16 byte alignment from the package. It is only an assumption
due to lack of the documentation and may be fixed in the future.

Feature allows to avoid unnecessary padding when package is part of
a message and preceeded by a header of a known size. For example,
message header on 32 bit architecture has 12 bytes, long doubles are
not used so cbprintf requires 8 byte alignment. Without alignment
offset indicator, package containing just a string with one argument
would need 4 byte padding after the header and 4 byte padding after
the package. Message would be 32 bytes long. With alignment offset
indication both paddings are not needed and message is only 24 bytes
long.

b1eefc0c26 lib/os/heap: straighten up our type usage
The size_t usage, especially in struct z_heap_bucket made the heap
header almost 2x bigger than it needs to be on 64-bit systems.
This prompted me to clean up our type usage to make the code more
efficient and easier to understand. From now on:

- chunkid_t is for absolute chunk position measured in chunk units
- chunksz_t is for chunk sizes measured in chunk units
- size_t is for buffer sizes measured in bytes

a54e101a1e lib/os/heap: rename struct z_heap.len to struct z_heap.end_chunk
The end marker chunk was represented by the len field of struct z_heap.
It is now renamed to end_chunk to make it more obvious what it is.

And while at it...

Given that it is used in size_too_big() to cap the allocation size
already, we no longer need to test the bucket index against the
biggest index possible derived from end_chunk in alloc_chunk(). The
corresponding bucket_idx() call is relatively expensive on some
architectures so avoiding it (turning it into a CHECK() instead) is
a good thing.
