adb69fcdff Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines, 
simplifies a lot of error handling code, and fixes many memory leaks.

897ff817d5 SF #1373150, diffs in working copy after a build 
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.

If anyone configures in a different directory, we might want a cleaner
approach using os.path.*().  Hopefully this is good enough.

f8d403dd97 SF #1377897, Bus error in ast 
If a line had multiple semi-colons and ended with a semi-colon, we would
loop too many times and access a NULL node.  Exit the loop early if
there are no more children.

af68c874a6 Add const to several API functions that take char *. 
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

4737b2348b Last batch of ref leaks in new AST code. 
Also converted a bunch of assert(0) to SystemError's.

There are still printfs, etc that need to be cleaned up.

c5dd10aa1d Write a separate ast_for_testlist_gexp() function instead of overloading 
ast_for_testlist().  Also, write a ast_for_class_bases() function and in
the process fix a memory leak.  Add some assertions.
