rand32.h does not make much sense, since the random subsystem
provides more APIs than just getting a random 32 bits value.
Rename it to random.h and get consistently with other
subsystems.

lib -> libraries to be consistent with everything else.
And fix identifier for a few stray tests that were wrongly
labeled/tagged.

Improve stress tests to be more robust and demanding. Previous
implementation did not reveal race condition.

Wrong value was used for free space calculation. Updating test which
previously was hiding this bug.

Add a bunch of missing "zephyr/" prefixes to #include statements in
various test and test framework files.

Refactoring test by adding macro for total packet length
calculation and header length.
Tuning test to trigger a scenario where free space was miscalculated.
Bug was fixed in the previous commit.

Extend test suite to validate zero copy API.
Add stress tests.
Add support for cache in the test. Test is not emulating cache
but ensures that buffer works correctly with cache enabled.

Added functions which allow to use zero copy model for handling
data within the packet buffer.
Additionally, added handling of cache by adding option to keep rd_idx
in different cache line than wr_idx and data.

This board has external cache enabled but fails to link when cache
API is used. Temporary disabling.

Add flags option to init call and a flag to use cache.
Add Kconfig choice to pick how to approach cache. Cache can be
enforced in all spsc_pbuf instances, disable in all, or runtime selected
based on configuration flag. Option is added to allow memory footprint
savings.

Move icmsg_buf to lib/os and rename to spsc_pbuf (Single Producer
Single Consumer Packet Buffer). It is a generic module and initially
was created as internal module for ipc service.
