Removes useless const declarations.

* Fixed most readability-non-const-parameter warnings

These changes were made automatically by clang-tidy, but I manually reverted the changes related to the H5Z_func_t signature.

* Reformat source with clang v10.0.1.

Co-authored-by: Larry Knox <lrknox@hdfgroup.org>

* Added C++11 override keyword where appropriate (#433)

Added H5_OVERRIDE macro for compatibility with both C++11 and older.

* Various clang tidy warning fixes (#448)

* Fixed clang-tidy bugprone-reserved-identifier warnings

* Fixed clang-tidy bugprone-assert-side-effect warnings

* Fixed clang-tidy bugprone-copy-constructor-init warning

* Fixed clang-tidy readability-redundant-preprocessor warning

For error_test.c the removed code was already dead, because it was in the else of an `#if H5_USE_16_API` block.

Based on H5Location.h, I think p_get_ref_obj_type was meant to be in `#ifndef DOXYGEN_SHOULD_SKIP_THIS` and an `#endif` was missing.  Similarly, in the header, getObjTypeByIdx is only in H5_NO_DEPRECATED_SYMBOLS, not DOXYGEN_SHOULD_SKIP_THIS.

* Fixed clang-tidy readability-redundant-string-init warnings

* Fixed some clang-tidy performance-type-promotion-in-math-fn warnings

* Fixed clang-tidy performance-unnecessary-value-param warnings

* Reformat source with clang v10.0.1.

Co-authored-by: Larry Knox <lrknox@hdfgroup.org>

After 30+ years, just assume that the following exist:
- extension-less includes
- namespaces
- std::
- static_cast
- bool

* Fixed all clang-tidy bugprone-suspicious-string-compare warnings (#451)

* Fixed all clang-tidy bugprone-suspicious-string-compare warnings

This change was generated entirely by clang-tidy itself.

* Reformat code with clang v10.0.1.

Co-authored-by: Larry Knox <lrknox@hdfgroup.org>

* File locks now work on Windows (#480)

* File locks now work on Windows

Uses LockFileEx() and UnlockFileEx(). Fixes HDFFV-10191 (partial).

* Committing clang-format changes

* Committing clang-format changes

* Fixes commenting in h5repack

* Reworks H5Fis_accessible()

H5Fis_accessible() created a new file handle and attempted to read
through it, which will fail when a file has been opened with an
exclusive lock on operating systems that have mandatory locks.

This change uses the same scheme we use in H5Fopen() to check if
the file is already open and only tries to read the file signature
if the file has not already been opened.

Also adds a test for this behavior.
