Refactor all the 'H5VL_*_optional' callbacks to move the type of operation out
of the va_list, so it's at least possible for another connector to know what the operation is and decide whether to implement it or not. Added a new VOL sub-class called "introspect" where callbacks that report information about the connector or container can be placed. Added an 'opt_query' callback to this sub-class, for a connector to report back to the library whether a particular optional callback operation is supported. Also added a 'get_conn_cls' introspection callback, to retrieve the H5VL_class_t of a connector (either the "current" connector, H5VL_GET_CONN_LVL_CURR, or the terminal connector, H5VL_GET_CONN_LVL_TERM). Moved the "post open" operation from a file 'specific' operation to a file 'optional' operation, now that it's possible to detect (with the 'opt_query' introspection callback) whether a VOL connector implements an optional operation, without just returning an error. Added new internal VOL helper routines: H5VL_object_is_native, to determine if an object is in (or is a) native file, and H5VL_file_is_same, to determine if two objects are in (or are) the same terminal VOL connector's container. (And moved the special handling for FILE_IS_EQUAL operation out of internal VOL callback routine into H5VL_file_is_same) Made new dataset 'get' operation for H5Dvlen_get_buf_size, aligning it better with other 'get' operations in API. Fixed several issues with pass-through connectors, which are now passing the 'make check-passthrough-vol' tests again. A bunch of warning and style cleanups as well.
