The CAS operation used the wrong function and the atomic_store operations
compiled into inadequate assembly on x86 and ARMv7.

Add atomic compare-and-swap
...
The atomic compare-and-swap can be used to implement lock-free
structures. The planned use for this is to remove some of the locking done
in the services when listeners are being manipulated.

Preparation for adding KILL syntax support.
Session id changed to uint32 everywhere. Added atomic op.

Worker object has a session_id->SESSION* mapping, not used yet.

Add atomic store and load operations
...
Added abstractions for storing and loading 32-bit and 64-bit values
atomically. The functions currently use the GCC __atomic builtin atomics.
