43d8b36518 Add atomic operations. 
This was initially copied from glib. How ever I have
simplified it to only support proper atomic operations
with gcc builtin __sync calls. The backup is pthread_spin_lock().
I have also obviously namespaced the code to qb_.

9e5385b885 qb_list_splice: don't splice an empty list 
An empty list passed to splice will damage the target splice list.  This patch
prevents that from happening by checking for an empty list and not merging
in that case.

the point is to use this for IPC to provide async

flow control.

This still needs a bit of clean up, but committing now
