Combo set of async and other changes (#161)
* Update API tracing for new H5VL_request_status_t typedef

* Apply patch for dynamically registering optional VOL operations
* (a) Add async APIs for H5O module as listed in jira issue ID-283.
(b) Remove verification of name parameter in async related routines for H55A and H5L modules
because it is checked in H5VL_setup* routine.
(c) Modify h5dump expected output due to the async changes.
* Corrections based on PR feedback.

* Committing clang-format changes
* Convert attribute 'get' operation to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Update tracing macros
* Convert attribute 'specific' operation to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Convert dataset 'get' and 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also, minor tweaks to attribute 'get' and 'specific' operation parameters.
* Convert datatype 'get' and 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also, minor tweaks to H5O_refresh_metadata arguments.
* Reduce warnings
* Reduce warnings
* Track change to datatype 'get' callback
* Fix bug with file pointer getting invalidated when object closed
* Reformat source
* Convert file and group VOL classes 'get' and 'specific' operations to use
struct-of-tagged-union pattern for VOL callback arguments, instead of using
varargs. Also small cleanup to the attribute get name operation. Also moved
'mount' and 'unmount' operations to be group specific operations, instead of
file specific, to better align with their behavior (mounted files are on
groups, so a group is what is operated on).
* Remove remainder of merge conflict marking
* Convert link VOL class 'create' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Remove some unused local variables
* Convert link VOL class 'get' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also refactor 'get name by idx' routines to return actual length of name with a parameter instead of the return value, and move some callback context structs for the link interface from the private header file into the source code module, to reduce their visibility scope.
* Update tracing macros
* Convert link VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Convert object VOL class 'get' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Convert object VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also refactor H5G_loc_exists, et al, to return 'exists' flag in a parameter and errors with the function return value, instead of overloading both into the return value. And, corrected logic error in test/links.c around non-existant objects in a file.
* Convert request VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs.
* Convert blob VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also removes the H5VL_BLOB_GETSIZE operation, as it's unused in the library and the blob ID size for a container is now returned with H5VL_FILE_GET_CONT_INFO.
* Add 'const' to several parameters that are only queried.
* Convert all VOL classes' 'optional' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Convert several 'get' routines to return the length of an array in a parameter instead of combining it into the return value. Move several routines to be in less public namespace. Correct direct_chunk test to verify that parameters aren't modified on error.
* Switch get/specific/optional VOL callback argument structures to be 'async-friendly'. Also other minor cleanups and bug-fixes.
* Add H5Pset_dataset_io_hyperslab_selection / H5S_PLIST feature, to allow skipping H5Dget_space + H5Sselect_hyperslab for async operation
* Add dynamic optional operations for request objects
* Update dynamic operation test for optional request operations
* Update a comment for an operation argument
* Run trace and format_source scripts
* Committing clang-format changes
* Committing clang-format changes
