Sync 1.14 branch with develop (#3887)

* Preserve MPI-I/O file hints when fapl is closed (#3755)

* Fix for issue #3025: Save the MPI info in the file struct so H5Fget_access_plist() can retrieve it from there.

* Add compression tests for subfiling (#3769)

* Fix typo in comment (#3775)

* Fixed a file handle leak in the core VFD (#3779)

When opening a file with the core VFD and a file image, if the file
already exists, the file check would leak the POSIX file handle.

Fixes GitHub issue #635

* Fix a format string warning in the C++ examples (#3776)

* Cancel running GitHub workflows on push to same PR (#3772)

* Cancel running GitHub workflows on push to same PR

Avoids overly verbose output from all processes emitting progress, etc. info.

* Avoid attempted use of NULL pointer in parallel compression code (#3786)

The parallel compression test code tests for the case where all MPI ranks have no selection in a dataset when writing to it. Add an early exit to the code to avoid attempting to use a NULL pointer due to there being no work to do.

* Set NVHPC maximum optimization level to -O1 for now

Compiling HDF5 with NVHPC 23.5 - 23.9 results in test failures in
4 different test files that need to be resolved. Since those tests
pass with an optimization level of -O1 (and -O0) and it is currently
unclear whether the test failures are due to issues in HDF5 or issues
in the 'nvc' compiler, set the maximum optimization level for NVHPC
to -O1 until the test failures are resolved.

* Disable FP exceptions in H5T init code (#3837)

The H5T floating-point datatype initialization code can raise exceptions when handling signaling NaNs. This change disables FE_INVALID exceptions during initialization.

Also removes the -ieee=full change for NAG Fortran as that shouldn't be necessary anymore.

Fixes #3831

* Add intel oneapi windows build to CI CMake (#3836)

* Remove printf format warning on Windows oneAPI. (#3838)

* Correct ENV variables (#3841)

* Remove Autotools sed hack (#3848)

configure.ac contains a sed line that cleans up incorrect library
flags which was added to paper over some bugs in earlier versions
of the Autotools. These issues are not a problem with the current
versions of the Autootols.

The sed line causes problems on MacOS, so it has been removed.

Fixes #3843

* Make filter unregister callbacks safe for VOL connectors (#3629)

* Make filter callbacks use top-level API functions

When using VOL connectors, H5I_iterate may not provide
valid object pointers to its callback. This change keeps
existing functionality in H5Zunregister() without using
potentially unsafe pointers.

* Filter callbacks use internal API

* Skip MPI work on non-native VOL

* Add extra space in comments for consistency (#3852)

* Add extra space in comments for consistency

* uncomment tfloatsattrs test

* Add CMake long double cross-compile defaults (#3683)

HDF5 performs a couple of checks at build time to see if long double
values can be converted correctly (IBM's Power architecture uses a
special format for long doubles). These checks were performed using
TRY_RUN, which is a problem when cross-compiling.

These checks now use default values appropriate for most non-Power
systems when cross-compiling. The cache values can be pre-set if
necessary, which will preempt both the TRY_RUN and the default.

Affected values:
    H5_LDOUBLE_TO_LONG_SPECIAL      (default no)
    H5_LONG_TO_LDOUBLE_SPECIAL      (default no)
    H5_LDOUBLE_TO_LLONG_ACCURATE    (default yes)
    H5_LLONG_TO_LDOUBLE_CORRECT     (default yes)
    H5_DISABLE_SOME_LDOUBLE_CONV    (default no)

Fixes GitHub #3585

* Updates for building and testing VOL connectors

* Fix issue with HDF5_VOL_ALLOW_EXTERNAL CMake variable

* Initialize parallel testing with MPI_THREAD_MULTIPLE when testing API

* Add CMake variable to allow specifying a VOL connector's package name

* Remove call to MPI_Init in serial API tests

While previously necessary, it now interferes with VOL connectors that
may need to be initialized with MPI_THREAD_MULTIPLE

* Fixes for CI and presets (#3853)

* Change dest for doxygen (#3856)

* Implement selection vector I/O with collective chunk filling (#3826)

* Changes for ECP-344: Implement selection vector I/O with collective chunk filling.
Also fix a bug in H5FD__mpio_write_vector() to account for fixed size optimization
when computing max address.

* Fixes based on PR review comments:
For H5Dchunk.c: fix H5MM_xfree()
For H5FDmpio.c:
1) Revert the fix to H5FD__mpio_write_vector()
2) Apply the patch from Neil on the proper length of s_sizes reported by H5FD__mpio_vector_build_types()

* Put back the logic of dividing up the work among all the mpi ranks similar to the
original H5D__chunk_collective_fill() routine.

* Add a test to verify the fix for the illegal reference problem in H5FD__mpio_write_vector().

* Do not publish compression headers or docs (#3865)

* Fix typo: look -> loop (#3866)

* Moved the README to markdown and expanded its overview of the files, file generation, and other Fortran wrapper development practices as mentioned in the HDF5 architectural document. I added a new figure and included the SVG file and the original xfig file it was generated from. (#3862)

* Add HDF5_DISABLE_TESTS_REGEX option to skip tests (#3859)

* Fix typo in error message for `MPI_Type_dup`. (#3867)

* Complete the `if command line option` sentence. (#3868)

* Fix h5dump segmentation fault when --vfd-value option is used (#3873)

* Updated URL in funding.yml (#3882)

Using new shortened URL, might look better.

* Remove unused variable from unmerged changes

* Update src/H5Tinit_float.c

+
+      The floating-point datatype initialization code in H5Tinit_float.c

-    IEEE standard arithmetic enables software to raise exceptions such as overflow,
-    division by zero, and other illegal operations without interrupting or halting
-    the program flow. The HDF5 C library intentionally performs these exceptions.
-    Therefore, the "-ieee=full" nagfor switch is necessary when compiling a program
-    to avoid stopping on an exception.
+    When HDF5 is compiled with NVHPC versions 23.5 - 23.9 (additional versions may
+    also be applicable) and with -O2 (or higher) and -DNDEBUG, test failures occur
+    in the following tests:
+
+        H5PLUGIN-filter_plugin
+        H5TEST-flush2
+        H5TEST-testhdf5-base
+        MPI_TEST_t_filters_parallel
+
+    Since these tests pass with an optimization level of -O1 (and -O0) and it is
+    currently unclear whether the test failures are due to issues in HDF5 or issues
+    in the 'nvc' compiler, the maximum optimization level for NVHPC has been set
+    to -O1 until the test failures can be resolved. Note that even at -O1 optimization
+    level, there still appears to be a sporadic test failure in the Java JUnit tests
+    that has occasionally been seen in JUnit-TestH5Pfapl and JUnit-TestH5D. It is also
+    unclear whether this is an issue in HDF5 or with the 'nvc' compiler. Finally, note
+    that NVHPC 23.9 will fail to compile the test/tselect.c test file with a compiler
+    error of 'use of undefined value' when the optimization level is -O2 or higher.
+    Nvidia is aware of this issue and has suggested lowering the optimization level to
+    -O1 for the time being:
