Log message:
    Make LANCOMPILER clause in CREATE LANGUAGE optional.  Allow "identifier"
    syntax for language names (instead of 'string').

    createlang now handles the case where a second language uses the same call
    handler as an already installed language (e.g., plperl/plperlu).

    droplang now handles the reverse case, i.e., dropping a language where
    the call handler is still used by another language.  Moreover, droplang
    can now be used to drop any user-defined language, not just the supplied
    ones.
