[1.12 Merge]Hdf5 1 12 warnings fixes (#1715)
* Warnings fixes (#1680)
* Clean stack size warnings in sio_engine (#1687)
* Fixes stack size warnings in tcoords.c (#1688)
* Address some warnings from casting away of const (#1684)
* Fixes stack size warnings in ntypes (#1695)
* Fixes stack size warnings in dtransform (#1696)
* Fixes stack size warnings in set_extent test (#1698)
* Be a bit safer with signed arithmetic, thus quieting some signed-overflow warnings from GCC (#1706)
* Avoid a signed overflow: check the range of `entry_ptr->age` before
increasing it instead of increasing it and then checking the range.
This quiets a GCC warning.
* Avoid the potential for signed overflow by rewriting expressions
`MAX(0, fwidth - n)` as `MAX(n, fwidth) - n` for various `n`.
This change quiets some GCC warnings.
* Change some local variables that cannot take sensible negative values
from signed to unsigned. This quiets GCC warnings about potential
signed overflow.
* In a handful of instances, check the range of a signed integer before
increasing/decreasing it, just in case the increase/decrease overflows.
This quiets a handful of GCC signed-overflow warnings.
* Committing clang-format changes

* Fix object size warnings in cache.c test (#1701)
* Fix some const cast and stack/static object size warnings (#1700)
* Fix various warnings
* Move HDfree_const to H5private.h for wider use
* Print output from all ranks in parallel tests on allocation failure
* Move const pointer freeing macro to h5test.h for now
* Stop lying about H5S_t const-ness (#1209)
Hyperslabs can be reworked inside several H5S callbacks, making H5S_t
non-const in some places where it is marked const. This change switches
these incorrectly const H5S_t pointer parameters and variables to
non-const where appropriate.
* Fix a few warnings after recent H5S const-related changes (#1225)
* Adjustments for HDF5 1.12
