Add parse_ddl_options(), append_ddl_option(), and append_guc_value() helper functions in a new ddlutils.c file that provide common option parsing and output formatting for the pg_get_*_ddl family of functions which will follow in later patches. These accept VARIADIC text arguments as alternating name/value pairs. Callers declare an array of DdlOption descriptors specifying the accepted option names and their types (boolean, text, or integer). parse_ddl_options() matches each supplied pair against the array, validates the value, and fills in the result fields. This descriptor-based scheme is based on an idea from Euler Taveira. This is placed in a new ddlutils.c file which will contain the pg_get_*_ddl functions.
