libglusterfs/atomic: Improved atomic support
This patch solves a detection problem in configure.ac that prevented
that compilation detects builtin __atomic or __sync functions.
It also adds more atomic types and support for other atomic functions.
An special case has been added to support 64-bit atomics on 32-bit
systems. The solution is to fallback to the mutex solution only for
64-bit atomics, but smaller atomic types will still take advantage
of builtins if available.
