Spin off just SkLazyFnPtr from 305513002. The memory barrier in SkOnce is a perf regression for sk_mem{set,cpy} in SkUtils on ARM. We can do a lot better for function pointers.

Atomics overhaul. This merges and refactors SkAtomics.h and SkBarriers.h into SkAtomics.h and some ports/ implementations. The major new feature is that we can express memory orders explicitly rather than only through comments. The porting layer is reduced to four template functions: - sk_atomic_load - sk_atomic_store - sk_atomic_fetch_add - sk_atomic_compare_exchange From those four we can reconstruct all our previous sk_atomic_foo. There are three ports: - SkAtomics_std: uses C++11 <atomic>, used with MSVC - SkAtomics_atomic: uses newer GCC/Clang intrinsics, used on not-MSVC where possible - SkAtomics_sync: uses older GCC/Clang intrinsics, used where SkAtomics_atomic not supported No public API changes.

Move sync code to include/, switch from using platform define to a proxy header in core/ This fixes two problems: 1) #include SK_SOME_DEFINE doesn't work well for all our clients. 2) Things in include/ are #including things in src/, which we don't like.
