Sync 1.14 branch with develop (#3705)
4a02890 
* Address nagfor exceptions stoppage. (#3658)

* added cmake ieee flag for nagfor

* generalized determining the nag compiler

* fixing some misc. NAG warnings

* Simplify. (#3659)


* Address @jhendersonHDF review

* Add expedited testing support to t_filters_parallel (#3665)

* Remove clang warnings (#3656)

* Fixes test failure for gfortran -O2 and -O3, -fdefault-real-16 (#3662)

* added cmake ieee flag for nagfor

* fixes gfortran -O2 and -O3, -fdefault-real-16

* fixed sync

* updated release notes

* Fix link error on clang17/gfortran13/macOS-13 (#3666) (#3671)

* Correct fortran CMake generator expressions (#3670)

* Add AOCC GitHub Action (#3504) (#3657)

* Fix uninitialized subfiling test variable (#3675)

Picked up by gcc 10 on skybridge. Probably spurious, but no harm in
initializing it to a "bad" value.

* Add support for AOCC & Flang w/ the Autotools (#3674)

* Adds a config/clang-fflags options file to support Flang
* Corrects missing "-Wl," from linker options in the libtool wrappers
  when using Flang, the MPI Fortran compiler wrappers, and building
  the shared library. This would often result in unrecognized options
  like -soname.
* Enable -nomp w/ Flang to avoid linking to the OpenMPI library.

CMake can build the parallel, shared library w/ Fortran using AOCC
and Flang, so no changes were needed for that build system.

Fixes GitHub issues #3439, #1588, #366, #280

* Fix a strncpy call to use dest size not src (#3677)

A strncpy call in a path construction call used the size of the src
buffer instead of the dest buffer as the limit n.

This was switched to use the dest size and properly terminate the
string if truncation occurs.

* Remove CANBE_UNUSED() from subfiling VFD (#3678)

This macro was an attempt to quiet warnings about release mode unused
variables that only appear in asserts. It resolves to a void cast, which
doesn't quiet warnings when an assignment has already taken place.

* Suppress MPI_Waitall warnings w/ MPICH (#3680)

MPICH defines MPI_STATUSES_IGNORE (a pointer) to 1, which raises warnings
w/ gcc. This is a known issue that the MPICH devs are not going to fix.

See here:
    pmodels/mpich#5687

This fix suppresses those issues w/ gcc

* Fix a possible NULL pointer dereference in tests (#3676)


The dtypes test could dereference a NULL pointer if a strdup call
failed.

* Fix printf warnings in t_mpi (#3679)

* Fix printf warnings in t_mpi

The type of MPI_Offset varies with implementation. In MPICH, it's long,
which raises warnings when we attempt to use long long format
specifiers. Casting to long long fixes the warnings.

* Fix invalid memory access in S3 comms (#3681)

In the ros3 VFD, passing an empty string parameter to an internal
API call could result in accessing the -1th element of a string.
This would cause failures on big-endian systems like s390x.

This parameter is now checked before writing to the string.

Fixes GitHub #1168

* Add Doxygen for H5Pset_fapl_sec2() (#3685)

*

* switch to using time function instead of date function (#3690)

* Initialize API context MPI types to MPI_BYTE (#3688)

* Add test info output to t_filters_parallel (#3696)

* Suppress format string warnings in subfiling test (#3699)

* Fix unused variable in tselect.c (#3701)

* Fix unused variable warning in H5F_sfile_assert_num (#3700)

* Restore floating-point suffixes in tests (#3698)

A prior commit removed too many F suffixes. This restores the suffixes
for float variables.

* Sync with changes from develop
