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.

The hifive_unleashed board is configured with 0xf0000000 bytes of memory,
so an allocation of 0x7fffffff should succeed. Instead, use a much larger
value to ensure that the allocation fails.

One test reads too few bytes from the source to ensure nul-termination of
the result which generates a compiler warning.

Picolibc excludes %n support on purpose as it can introduce security issues
when the format string is vulnerable to manipulation.

Passing NULL as the stream to stdio functions is "UB" (undefined behavior)
in the C standard. Picolibc crashes in this case, which is valid, but not
helpful. Skip these tests in this case.

When the compiler is allowed to know the semantics of malloc and free,
this test needs to be careful to not have both calls elided by not using
the result at all. Simply storing the malloc pointer in a global
variable is sufficient here.

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.

This adds some bits to support tagged arguments to be used for
packaging. If enabled, the packaging function no longer looks at
the format strings to determine the types of arguments, but
instead, each argument is tagged with a type by preceding it
with another argument as type (integer). This allows the format
strings to be removed from the final binary to conserve space.

This commit introduces a new configuration called
`CONFIG_MINIMAL_LIBC_NON_REENTRANT_FUNCTIONS`, which enables the
traditional non-reentrant (i.e. not thread-safe) version of the C
standard library functions such as rand() and gmtime() when the
respective configs are enabled.
The non-reentrant functions make use of the globals and require an
additional memory partition (MPU region), which is scarce on low-end
devices, when CONFIG_USERSPACE=y.
The purpose of this option is to classify the MPU resource intensive
functions as a separate category and only enable them when there is a
demand for such.

qsort_r is a GNU addition, so we need to #define _GNU_SOURCE to ensure

We need to keep gcc from complaining about large calloc/malloc/realloc
sizes as that's what we're testing.
Define _BSD_SOURCE so that libraries sharing the glibc convention (like
newlib and picolibc) for controlling the API level visible to applications
will declare reallocarray(3), which is an OpenBSD extension to the C

Some test suites have different test case lists in test_main(), that
conforms to different test scenarios defined in testcase.yaml. We
use if statement to decide which test case list should run under
specific config.
But for thoses boards who do not support those configs, we will run test
cases on the other side of the if statement even if it has deviated from
the original test scenario.
So add filter to avoid test scenario running under mismatch config.

Instead of relying on runtime filter to limit scope to emulation
platforms, use the type attribute for each platform and do the filtering
very early on. This will speed things up for tests where we only run on
emulation platforms.
