libc: minimal: add console system calls The stdout console implementations for minimal libc call directly into the various console drivers (depending on what specifc hooks are registered) causing faults when invoked from user mode. This happens, for example, when using printf() which eventually ends up calling fputc(). The proper solution is to ensure privileges have been elevated before the _stdout_hook is called. This was already done for printk(). puts() and fputs() have now been re-defined in terms of the fputc() and fwrite() functions, which are now system calls.

libc: set up memory partitions * Newlib now defines a special z_newlib_partition containing all globals relevant to newlib. Most of these are in libc.a with a heap tracking variable in newlib's hooks. * Both C libraries now expose a k_mem_partition containing the bounds of the malloc heap arena. Threads that want to use libc malloc() will need to add this to their memory domain. * z_newlib_get_heap_bounds has been removed, in favor of the memory partition for the heap arena * ztest now includes the C library partitions in its memory domain. * The mem_alloc test now runs in user mode to prove that this all works for both C libraries.
