using the new routine H5FDdeduplicate().
Simplify H5F_open() a bit, pushing some of the configuration checks into the
SMWR VFD. For example, check that page buffering is enabled in
H5FD_vfd_swmr_open() instead of in H5F_open(). Compare VFD SWMR configurations
in H5FD_vfd_swmr_dedup() instead of in H5F_open().
Clone the default file-access property list at a new file-access property list
ID, H5P_FILE_ACCESS_ANY_VFD. The new ID is used to indicate that if the file
that's being opened is already open under an existing virtual file, and if that
virtual file would not ordinarily be opened with the default FAPL, then it's ok
to use that virtual file.
Add a new optional method, `dedup`, to H5FD_class_t, and use it to customize a
VFD's deduplication.
Customize the SWMR VFD's deduplication. Make it honor H5P_FILE_ACCESS_ANY_VFD
Embed the VFD SWMR configuration in the H5FD_vfd_swmr_t to facilitate
comparison of configuration between new and old SWMR virtual files.
In H5F__sfile_search(), match using a pointer comparison instead of H5FD_cmp(),
because we will only ever enter H5F__sfile_search() with a deduplicated
H5FD_t *.
Mismatch in time of test file creation was creating false negatives.
Add file-duplication routine: `h5_duplicate_file_by_bytes()`.
* Change library calls in `h5test.c:h5_compare_file_bytes()` to their HD-prefixed equivalents.
* "Simultaneous and equivalent" Read-Write and Write-Only channels for
file I/O.
* Only supports drivers with the H5FD_FEAT_DEFAULT_VFD_COMPATIBLE flag for
now, preventing issues with multi-file drivers.
Add Mirror VFD to library.
* Write-only operations over a network.
* Uses TCP/IP sockets.
* Server and auxiliary server-shutdown programs provided in a new directory,
`utils/mirror_vfd`.
* Automated testing via loopback ("remote" of localhost).

including the merge of `hdffv/hdf5/develop`, back to the branch that Vailin and
I share.
Now I need to put this branch on a fork with a less confusing name than
vchoi_fork!
This implicitly adds support for changing the VOL connector for command-line
tools or any application linked with the library.
Also, add 'make check-vol' support for all directories, clearing up necessary
issues in testing scripts, etc.
src/H5VLpassthru.c, switched to stashing VOL connector ID & info in
API context (in src/H5CX.c, src/H5CXprivate.h, src/H5F.c, src/H5Fint.c, and
src/H5Fefc.c), patched up all sorts of issues in the tests, to make them work
with 'check-vfd' (and 'check-vol' again).
