Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

This patch introduces wrappers to the built-in atomic operations provided by
gcc.
There are two sets of built-in atomic functions available. Before gcc 4.7.0 only
the __sync built-in functions are available, while since 4.7.0 a new set of
built-in functions with the __atomic prefix is introduced as a
replacement. Since the __sync functions will eventually be deprecated, the
__atomic ones are preferred whenever available.
The interfaces provided are listed below, mostly following the naming of the
underlying built-in functions which explain themselves.
atomic_load
atomic_store
atomic_xchg
atomic_cmpxchg
atomic_add_fetch
atomic_sub_fetch
atomic_and_fetch
atomic_xor_fetch
atomic_or_fetch
atomic_nand_fetch
atomic_fetch_add
atomic_fetch_sub
atomic_fetch_and
atomic_fetch_xor
atomic_fetch_or
atomic_fetch_nand
atomic_test_and_set
atomic_clear
atomic_thread_fence
atomic_signal_fence
