Combo set of async and other changes (#161)
* Update API tracing for new H5VL_request_status_t typedef * Finish converting internal event set operations to use list iterator callbacks, instead of directly accessing the list structure * Add H5VL_REQUEST_GET_ERR_STACK operation to request subclass, for retrieving a copy of the error stack for a failed asynchronous operation * Remove 'canceled' event status from Java constants * Be safer about releasing resources when inserting a newly opened/created object or file into an event set * Remove H5EStest, add H5ES_WAIT_NONE for 0 timeout, and revise parameters to H5ESwait, to make it more "aggregate". * Remove H5ES_STATUS_CANCELED from Java wrappers also * 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. * Further changes to make based on PR feedback. * Remove H5Dwait & H5Fwait (moved to the async connector).

Don't set up VOL wrappers for 'infrastructure' objects like requests and blobs * Fix warning about formatting a directory * Clean up formatting for H5E_BEGIN_TRY / H5E_END_TRY * Reduce scope of H5ES__close * Enable CMake checks for various types on MacOS * Clean up properly when H5CX_retrieve_state() fails. Also clean up many compiler warnings. * Committing clang-format changes * Merge from develop * Fix mis-placed assert * Remove commented-out code * Re-add macro for unsetenv on Windows (I think it accidentally was merged out) * Strengthen sanity check from error report to assertion * Committing clang-format changes * Add units to the comments for a few fields * Switch 'get execution time' operation for async request tokens to be an optional operation and query if connector supports operation before retrieving it. * Committing clang-format changes * Remove H5ESget_time_estimate * Committing clang-format changes * Create developer header for datatype routines and move type conversion register/unregister routines there. * Simplify internal H5VL_setup_name_args and H5VL_setup_idx_args routines * Add H5VLlink_optional_op, allowing dynamicly registered optional operations for the link VOL subclass, also added H5VL_loc_params argument to the link 'optional' callback to allow them to work correctly. * Run bin/format_source on current code * Add H5VLobject_optional_op, allowing dynamicly registered optional operations for the object VOL subclass, also added H5VL_loc_params argument to the object 'optional' callback to allow them to work correctly. * Run bin/format_source on current code * Committing clang-format changes * Revert "Switch 'get execution time' operation for async request tokens to be an optional operation and query if connector supports operation before retrieving it." This reverts commit 5ac92014da2682bdba62d7a2524b8d90e38f6b19. * 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 Co-authored-by: vchoi <vchoi@jelly.ad.hdfgroup.org> Co-authored-by: vchoi-hdfgroup <55293060+vchoi-hdfgroup@users.noreply.github.com> Co-authored-by: jhendersonHDF <jhenderson@hdfgroup.org> Co-authored-by: Dana Robinson <derobins@hdfgroup.org> Co-authored-by: Dana Robinson <43805+derobins@users.noreply.github.com> Co-authored-by: bmribler <39579120+bmribler@users.noreply.github.com> Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>
