Hi Thomas,
This patch adds the OpenACC 2.5 new APIs of acc_get_default_async/acc_set_default_async,
contained are the modifications for Fortran in libgomp/openacc.f90, libgomp/openacc_lib.h.

Not much is changed since the last submission of this part, except that the libgomp.map
part is moved to be included here, since its related to the exported API additions.

Thanks,
Chung-Lin

     * openacc.h (acc_async_t): Add acc_async_default enum.
     (acc_set_default_async): Declare API function.
     (acc_get_default_async): Likewise.

     * libgomp.map (OACC_2.5): Add acc_get_default_async,
     acc_get_default_async_h_, acc_set_default_async, and
     acc_set_default_async_h_.

     * openacc.f90 (acc_async_default): Declare.
     (acc_set_default_async): Likewise.
     (acc_get_default_async): Likewise.
      * openacc_lib.h (acc_async_default): Declare.
      (acc_set_default_async): Likewise.
     (acc_get_default_async): Likewise.
