Hdf5 1 12 Miscellaneous warnings fixes (#1718)
* Fixes const issues in the version 2 B-trees (#1172)
The operations that were changed are fundamentally not const since the
shadow operation can modify the node structure when SWMR is in use.
* Quiets const warning in H5RS code (#1181)
* Avoid calling H5Ropen_object with a misaligned H5R_ref_t: copy the (#1171)
* Avoid calling H5Ropen_object with a misaligned H5R_ref_t: copy the
raw H5R_ref_t bytes to a heap buffer that's known to have the right
alignment.
* Committing clang-format changes
* Use an automatic H5R_ref_t instead of malloc'ing one. Go ahead and
initialize the H5R_ref_t to all-0s so that arbitrary stack content
doesn't foul things up. Bail out with an error if `size` exceeds
`sizeof(H5R_ref_t)`.
* Committing clang-format changes
