    Remove error procedure directives
    
    Back in the wonderful old days of Mach 2, when there were no send-once
    rights, dead names, or port reference counts, MIG used to have more
    kinds of operations: there were functions, procedures, simpleprocedures,
    routines, and simpleroutines. Routines returned an error code as their C
    function return value, functions had real return values, procedures and
    simpleprocedures returned void.
    
    Functions, procedures, and simpleprocedures signalled errors by invoking
    a global function. By default, a function named MsgError was invoked,
    but a subsystem could specify a different function using the 'error'
    directive:
    
    error CustomErrorHandler;
    
    In Mach 3, functions, procedures, and simpleprocedures are gone.
    Routines and simpleroutines are the only remaining kinds of operations.
    Some 26 years later, most of the code for generating functions,
    procedures, and simpleprocedures was removed from GNU MIG in commit
    7f10b4ed6a557b7a1fd1083939156a3dcf8b377e. Error directives remained,
    seemingly due to an oversight. So remove them too.
    
    Found while trying to use the word 'error' as an identifier and
    receiving a cryptic syntax error from MIG.
