VFD ctl feature (#981)
* Added "ctl" callback to the VFD interface, and the associated H5FDctl() and H5FD_ctl() calls. Modified the MPIO VFD accordingly -- specifically: Added ctl() call with op-code support to expose rank, size, and communicator. Modified H5FD_mpi_get_rank(), H5FD_mpi_get_size(), and H5FD_mpi_get_comm() to use the new ctl() callback. In passing removed the const qualifier from the file parameter of these functions, as the file parameter of the ctl callback is not const. Deleted the old H5FD__mpio_mpi_rank(), H5FD__mpio_mpi_size(), and H5FD__mpio_communicator() calls from the MPIO VFD. Deleted H5FD_class_mpi_t from H5FDprivate.h, and modified the MPIO VFD accordingly. Note that all VFDs now use H5FD_class_t, with no special class for VFDs that that support MPI. Some minor touch ups to the Neil's selection I/O mods in passing. Tested serial and parallel, debug and production on charis and jelly. * Reserve a range of VFD "ctl" opcodes for library and experimental usage * Add "ctl" callbacks to passthrough VFDs * Add RELEASE.txt entry for "ctl" callback * Use H5FDopen with H5F_ACC_RDWR flag instead of H5F_ACC_TRUNC in vfd test * Remove handling of passthrough "ctl" flag from multi VFD * Move logic for testing H5FD_CTL__TEST_OPCODE into a testing VFD Revise description of "ctl" callback in RELEASE.txt Remove unused H5FD_CTL__NUM_OPCODES definition Fix some warnings in multi VFD Co-authored-by: mainzer <mainzer#hdfgroup.org>
