VFD SWMR: Merges from develop (#1670)
* Cleans up SWMR test scripts (both legacy and VFD)
* Brings over format source changes for Java
* Normalization of HL, Fortran, C++, Java w/ develop
* Removes the STATIC flavor of FUNC_ENTER macros (#1622)
* Removes the STATIC flavor of FUNC_ENTER macros
* Remove H5_NO_ALIGNMENT_RESTRICTIONS (#1426)
* Do not conditionally compile code that uses a pointer dereference
and assignment to copy a potentially unaligned variable to aligned
automatic storage, or vice versa. Instead, always use naked `memcpy(3)`s.
Disassembling the generated code reveals that the `memcpy(3)`s optimize
(`-O3`) to a single `mov` instruction for x86_64, which is not strict
about alignment.
This change reduces the size of code and scripts by 143 lines, eases
our way to cross-compilation, and avoids invoking undefined behavior.
* Committing clang-format changes
* Per discussion, use HD and add comments.

* Removes unused definitions from module headers (#1624)
* Misc stuff from develop (includes some parallel things)
