Andy Ross 85e96ff3ca lib/os: Add sys_multi_heap utility
This is a simple wrapper allowing multiple sys_heap regions to be
unified under a single allocation API.  Sometimes apps need the
ability to share multiple discontiguous regions in a single "heap", or
to have memory of different "types" be allocated heuristically based
on usage (e.g. cacheability, latency, power...).  This allows a
user-specified function to select the underlying memory to use for
each application.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
