Remove all uses of alloca() from this module.  The alloca() return value
isn't checked, and it *is* possible that a very large alloca() call is
made, e.g. when a large registry value is being read.  I don't know if
alloca() in that case returns NULL or returns a pointer pointing outside
the stack, and I don't want to know -- I've simply replaced all calls to
alloca() with either PyMem_Malloc() or PyString_FromStringAndSize(NULL,)
as appropriate, followed by a size check.  This addresses SF buf 851056.

/* Error codes passed around between file input, tokenizer, parser and
   interpreter.  This is necessary so we can turn them into Python
   exceptions at a higher level.  Note that some errors have a
   slightly different meaning when passed from the tokenizer to the
   parser than when passed from the parser to the interpreter; e.g.
   the parser only returns E_EOF when it hits EOF immediately, and it
   never returns E_OK. */
