Implement ID creation optimization for container datatype conversions (#4113)
Makes the datatype conversion context object available during both the initialization and conversion processes for a datatype conversion function, allowing the compound, variable-length and array datatype conversion functions to avoid creating IDs for the datatypes when they aren't necessary Adds internal H5CX_pushed routine to determine if an API context is available to retrieve values from Also adds error checking to several places in H5T.c and H5Tconv.c where the code had previously assumed object close operations would succeed
