Roberto Ierusalimschy 3cadc37f47 no more 'Proto' objects on the stack. Protos are anchored on outer 
Protos or on a Closure, which must be created before the Proto.

Roberto Ierusalimschy 59bcd137ae reducing even more use of C stack by the parser: struct 'FuncState' 
does not need field 'L' + number of labels/gotos in a chunk may be
limited to SHRT_MAX. (Also removed some non-needed 'unsigned's.)
