Documentation/locking/atomic: Add documents for new atomic_t APIs Since we've vastly expanded the atomic_t interface in recent years the existing documentation is woefully out of date and people seem to get confused a bit. Start a new document to hopefully better explain the current state of affairs. The old atomic_ops.txt also covers bitmaps and a few more details so this is not a full replacement and we'll therefore keep that document around until such a time that we've managed to write more text to cover its entire. Also please, ReST people, go away.
