mpi_test analog

[Wei-keng Liao]

Hi, Jim,

The "non-blocking" APIs in pnetcdf are not truly asynchronous.
They actually defer the I/O requests till ncmpi_wait_all.
So, if there is a corresponding test call and it is called
in between the post of nonblocking and wait, it will simply
return false, indicating not yet complete.

Given that, would you still like to see a test API available
in pnetcdf? (That will not be too hard to add one.)
