Martin Åberg 80b9080f9d tests/mem_alloc: check that malloc() objects can be accessed
Adds tests checking that we can use memory allocated by malloc(),
calloc() and realloc() to access objects of some common types,
including uint64_t and double.

It works by doing a number of allocations of various sizes and
dereferencing the returned pointer. The purpose is to catch cases where
the application would trap if accessing the allocated memory. (The
test does not check alignment against the ABI or alignof().)

Title: Kernel Access to Dynamic Memory Allocation functions provided by
Standard Libraries

Description:

This test verifies kernel access to the dynamic memory allocation functions
provided by standard C libraries supported in Zephyr:
NEWLIB and MINIMAL_LIB.
It is intended to catch issues in which a library is completely absent
or non-functional, and is NOT intended to be a comprehensive test suite
of all functionality provided by the libraries.

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by outdated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
