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 *.

multiple opens of the same file with VFD SWMR---i.e., twice for writing, or for

of the SWMR functionality in the VFD, too.

the lower virtual file's `exc_owner` field. While I'm here, remove a
gratuitous assertion.
This is part of a changeset that helps us avoid creating multiple H5F_shared_t
for one file when virtual datasets are used with VFD SWMR. The old code for
deduplicating VFD SWMR H5F_shared_t instances did not work correctly with VFD
SWMR, so we'd end up with multiple H5F_shared_t all active on the same file.

member to all virtual files. Add a routine, H5FD_has_conflict(), that returns
true if a new virtual file is identical to an existing virtual file that has an
exclusive owner. Establish an exclusive owner for a VFD SWMR virtual file's
lower virtual file.
Rename bsdqueue.h to H5queue.h and install it, since it's used by H5FDpublic.h.

that are longer than the buffer that the caller supplied: the checksum
usually will fail, but that's not actually a fatal condition, and
usually we will have another opportunity to verify the checksum.
In H5FD_vfd_swmr_read(), remove a bunch of disused code.
In H5FD_vfd_swmr_read(), do not re-read a shadow image that has a
bad checksum, because a bad checksum indicates a serious problem
(writer outran reader, OS defect, hardware failure) from which
H5FD_vfd_swmr_read() cannot recover.
Rationale: the writer write(2)s new shadow images before the new index,
and the new index before the new header. In H5FD_vfd_swmr_read(),
the reader has read(2) both the index and the header in full. POSIX
semantics indicate that in these circumstances, the last shadow image
write(2) MUST be completely visible when we read(2). That is, the index
write(2) & read(2) and the header write(2) & read(2) pair cannot
divide a preceding shadow-image write(2).
The reader may see a "torn" image at this juncture if, for example,
the writer got max_lag ticks ahead of it and reused the storage for
this shadow image. Even if the reader "recovers" by re-reading the
image until its checksum is correct, it cannot be sure that the
image thus read is the right one for the HDF5 address passed to
H5FD_vfd_swmr_read(), and it cannot be sure that the image thus read is
not stale, because it's operating with an out-of-date shadow index.
Add log outlets swmr_read, swmr_read_exception, and swmr_read_err.
Log to `swmr_read` on entry to H5FD_vfd_swmr_read(), log to
`swmr_read_exception` when checksums are skipped for exceptional
conditions (page buffer not configured, buffer shorter than shadow
image), and log to `swmr_read_err` when the checksum fails.

tells whether the call may wait for the reader tick to catch up.
Add stub routines vfd_swmr_writer_may_increase_tick_to() and
vfd_swmr_reader_did_increase_tick_to() for tests---e.g.,
vfd_swmr_zoo_writer/_reader---to use to coordinate their tick numbers.
vfd_swmr_writer_may_increase_tick_to(new_tick, wait_for_reader) returns
true if the writer may increase its tick number to `new_tick` without
overrunning the reader.
A reader uses vfd_swmr_reader_did_increase_tick_to() to tell a writer
that its tick number has increased.

Poison writes to addr by making it const. Don't increase addr in the read(2)

Delete some more dead code.
Rename read_ptr as p and declare it much closer to its use. Change its type to
`char *` so that no casts are necessary to increase it.
