Improve ethread atomics
The ethread atomics API now also provide double word size atomics. Double word size atomics are implemented using native atomic instructions on x86 (when the cmpxchg8b instruction is available) and on x86_64 (when the cmpxchg16b instruction is available). On other hardware where 32-bit atomics or word size atomics are available, an optimized fallback is used; otherwise, a spinlock, or a mutex based fallback is used. The ethread library now performs runtime tests for presence of hardware features, such as for example SSE2 instructions, instead of requiring this to be determined at compile time. There are now functions implementing each atomic operation with the following implied memory barrier semantics: none, read, write, acquire, release, and full. Some of the operation-barrier combinations aren't especially useful. But instead of filtering useful ones out, and potentially miss a useful one, we implement them all. A much smaller set of functionality for native atomics are required to be implemented than before. More or less only cmpxchg and a membar macro are required to be implemented for each atomic size. Other functions will automatically be constructed from these. It is, of course, often wise to implement more that this if possible from a performance perspective.

+/*
+ * This file maps native atomic implementations to ethread
+ * API atomics. If no native atomic implementation
+ * is available, a less efficient fallback is used instead.
+ * The API consists of 32-bit size, word size (pointer size),
+ * and double word size atomics.
+ *
+ * The following atomic operations are implemented for
+ * 32-bit size, and word size atomics:
+ * - cmpxchg
+ * - xchg
+ * - set
+ * - init
+ * - add_read
+ * - read
+ * - inc_read
+ * - dec_read
+ * - add
+ * - inc
+ * - dec
+ * - read_band
+ * - read_bor
+ *
+ * The following atomic operations are implemented for
+ * double word size atomics:
+ * - cmpxchg
+ * - set
+ * - read
+ * - init
+ *
+ * Appart from a function implementing the atomic operation
+ * with unspecified memory barrier semantics, there are
+ * functions implementing each operation with the following
+ * memory barrier semantics:
+ * - rb (read barrier)
+ * - wb (write barrier)
+ * - acqb (acquire barrier)
+ * - relb (release barrier)
+ * - mb (full memory barrier)
+ *
+ * We implement all of these operation/barrier
+ * combinations, regardless of whether they are useful
+ * or not (some of them are useless).
+ *
+ * Double word size atomic functions are on the followning
+ * form:
+ * ethr_dw_atomic_<OP>[_<BARRIER>]
+ *
+ * Word size atomic functions are on the followning
+ * form:
+ * ethr_atomic_<OP>[_<BARRIER>]
+ *
+ * 32-bit size atomic functions are on the followning
+ * form:
+ * ethr_atomic32_<OP>[_<BARRIER>]
+ *
+ * Apart from the operation/barrier functions
+ * described above also 'addr' functions are implemented
+ * which return the actual memory address used of the
+ * atomic variable. The 'addr' functions have no barrier
+ * versions.
+ *
+ * The native atomic implementation does not need to
+ * implement all operation/barrier combinations.
+ * Functions that have no native implementation will be
+ * constructed from existing native functionality. These
+ * functions will perform the wanted operation and will
+ * produce sufficient memory barriers, but may
+ * in some cases be less efficient than pure native
+ * versions.
+ *
+ * When we create ethread API operation/barrier functions by
+ * adding barriers before and after native operations it is
+ * assumed that:
+ * - A native read operation begins, and ends with a load.
+ * - A native set operation begins, and ends with a store.
+ * - An init operation begins with either a load, or a store,
+ * and ends with either a load, or a store.
+ * - All other operations begins with a load, and ends with
+ * either a load, or a store.
+ *
+ * This is the minimum functionality that a native
+ * implementation needs to provide:
+ *
+ * - Functions that need to be implemented:
+ *
+ * - ethr_native_[dw_|su_dw_]atomic[BITS]_addr
+ * - ethr_native_[dw_|su_dw_]atomic[BITS]_cmpxchg[_<BARRIER>]
+ * (at least one cmpxchg of optional barrier)
+ *
+ * - Macros that needs to be defined:
+ *
+ * A macro informing about the presence of the native
+ * implementation:
+ *
+ * - ETHR_HAVE_NATIVE_[DW_|SU_DW_]ATOMIC[BITS]
+ *
+ * A macro naming (a string constant) the implementation:
+ *
+ * - ETHR_NATIVE_[DW_]ATOMIC[BITS]_IMPL
+ *
+ * Each implemented native atomic function has to
+ * be accompanied by a defined macro on the following
+ * form informing about its presence:
+ *
+ * - ETHR_HAVE_ETHR_NATIVE_[DW_|SU_DW_]ATOMIC[BITS]_<OP>[_<BARRIER>]
+ *
+ * A (sparc-v9 style) membar macro:
+ *
+ * - ETHR_MEMBAR(B)
+ *
+ * Which takes a combination of the following macros
+ * or:ed (using |) together:
+ *
+ * - ETHR_LoadLoad
+ * - ETHR_LoadStore
+ * - ETHR_StoreLoad
+ * - ETHR_StoreStore
