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.

3dc5475e23 'nCcalls' should be local to each thread, as each thread may have its
own C stack (with LuaThreads or something similar)

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.)
