This commit updates the entire codebase to use specific opal types for all atomic variables. This is a change from the prior atomic support which required the use of the volatile keyword. This is the first step towards implementing support for C11 atomics as that interface requires the use of types declared with the _Atomic keyword. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
