Demo/Posix_GCC: add demo application for Posix port using GCC

This is largely a copy of the Windows demo application with a few key changes: - heap_3 (use malloc()/free()) so tools like valgrind "just work". - printf() wrapped in a mutex to prevent deadlocks on the internal pthread mutexes inside printf(). SCons (https://scons.org/) is used as the build system. This will be built as a 64-bit application, but note that the memory allocation trace points only record the lower 32-bits of the address.
