Log Message: ----------- examples: use atomic_flag type, __sync functions

Use atomic_flag type and the GCC __sync built-in functions for atomic memory access. Initialize using ATOMIC_FLAG_INIT as a compound literal or a cast if scalar type depending on which atomic.h is used.

The Linux client clears shared memory in ipi_shmem_echo(). Do not clear it again from the RPU in ipi_shmem_echod() to avoid a race.
