Sync with develop (#3737)

* Correct ld in format strings in cmpd_dset.c (#3697)

Removes clang warnings

* Clean up comments. (#3695)

* Add NVidia compiler support and CI (#3686)

* Work around Theta system issue failure in links test (#3710)

When the Subfiling VFD is enabled, the links test may
try to initialize the Subfiling VFD and call MPI_Init_thread.
On Theta, this appears to have an issue that will cause
the links test to fail. Reworked the test to check for
the same conditions in a more roundabout way that doesn't
involved initializing the Subfiling VFD

* Fix issue with unmatched messages in ph5diff (#3719)

* provide an alternative to mapfile for older bash (#3717)

* Attempt to quiet some warnings with cray compilers. (#3724)

* Fix CMake VOL passthrough tests by copying files to correct directory (#3721)

* Develop intel split (#3722)

* Split intel compiler flags into sub-folders
* Update Intel options for warnings
* Mostly CMake, Autotools needs additional work

* Fixes and adjustments to t_filters_parallel (#3714)

Broadcast number of datasets to create in multi-dataset I/O cases
so that interference with random number generation doesn't cause
mismatches between ranks

Set fill time for datasets to "never" by default and adjust on a
per-test basis to avoid writing fill values to chunks when it's
unnecessary

Reduce number of loops run in some tests when performing multi-dataset
I/O

Fix an issue in the "fill time never" test where data verification
could fill if file space reuse causes application buffers to be
filled with chosen fill value when reading from datasets with
uninitialized storage

Skip multi-chunk I/O test configurations for multi-dataset I/O
configurations when the TestExpress level is > 1 since those
tests can be more stressful on the file system

Disable use of persistent file free space management for now
since it occasionally runs into an infinite loop in the library's
free space management code

* Suppress cast-qual warning in H5TB Fortran wrapper (#3728)

This interface is fundamentally broken, const-wise.

* Add new API function H5Pget_actual_select_io_mode() (#2974)

This function allows the user to determine if the library performed selection I/O, vector I/O, or scalar (legacy) I/O during the last HDF5 operation performed with the provided DXPL. Expanded existing tests to check this functionality.

* Test scripts now execute in-source with creation of tmp dir (#3723)

Fixes a few issues created in #3580:

* Fixes a problem where committed tools test files were deleted when cleaning after an in-source build
* Fixes issues with test file paths in Autotools tools test scripts

* Add -h and --help as flags in h5cc & h5fc (#3729)

Adds these common help flags in addition to -help

* Update the library version matrix for H5Pset_libver_bounds() (#3702)

* Fixed #3524

Added 1.12, 1.14, and 1.16 to the table for libver bounds in the H5Pset_libver_bounds docs.

* Remove references to LIBVER_V116
