1) Core changes for adding NFS/updater support as described in the RFC.

src/H5Pfapl.c
src/H5Fvfd_swmr.c
src/H5Fpublic.h
src/H5Fpkg.h
src/H5Fprivate.h

2) For VFD SWMR testing, add private property for checksum generation of metadata files:
src/H5Fint.c
src/H5Fvfd_swmr.c
src/H5Pfapl.c
src/H5Fpkg.h
src/H5Fprivate.h

3) Fix the following in H5F_vfd_swmr_init() and H5F_vfd_swmr_close_or_flush():
(a) Allocate metadata file index right after metadata file header.
(b) Set tick number to 0 when creating header and index for file open case.
(c) Remove tick number increment at file close.
src/H5Fvfd_swmr.c
src/H5Ftest.c

4) To be consistent with the RFC, change the name for field "chksum" to "checksum" in struct H5FD_vfd_swmr_idx_entry_t:
src/H5FDprivate.h
src/H5FDtest.c
src/H5FDvfd_swmr.c
src/H5Ftest.c
src/H5PB.c

4) Add tests for NFS/updater
test/vfd_swmr.c

5) Modify common routine init_vfd_swmr_config() to accept updater_file_path
test/vfd_swmr_common.c
test/vfd_swmr_common.h

6) Changes to the tests due to the common routine init_vfd_swmr_config():
test/vfd_swmr_addrem_writer.c
test/vfd_swmr_attrdset_writer.c
test/vfd_swmr_bigset_writer.c
test/vfd_swmr_dsetchks_writer.c
test/vfd_swmr_dsetops_writer.c
test/vfd_swmr_generator.c
test/vfd_swmr_gfail_writer.c
test/vfd_swmr_gperf_writer.c
test/vfd_swmr_group_writer.c
test/vfd_swmr_reader.c
test/vfd_swmr_remove_reader.c
test/vfd_swmr_remove_writer.c
test/vfd_swmr_sparse_reader.c
test/vfd_swmr_sparse_writer.c
test/vfd_swmr_vlstr_reader.c
test/vfd_swmr_vlstr_writer.c
test/vfd_swmr_writer.c
test/page_buffer.c
