577b5b960d Create _ast module. 
Cleanup Python-ast.c generation.

dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It 
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

59090a7334 Oops, I forgot to check this in with the change to Grammar/Grammar. 
Implement change suggested by Jiwon Seo on python-dev.
['(' gen_for ')'] is redundant with test, so remove it.

ultimately going to snprintf() not the python string formatter.  Right?

82a9394237 Add doc discussing how AST compiler is structured and designed. 
It is out of date, though, thanks to lacking info on the arena API.  It also
should eventually be removed in favor of updating PEP 339.

c960f26044 Improved handling of syntax errors. 
Expand set of errors caught in set_context().  Some new errors, some
old error messages changed for consistency.

Fixed error checking in generator expression code.  The first set of
tests were impossible condition given the grammar.  In general, the
ast code uses REQ() for those sanity checks.

Fix some error handling for augmented assignments.  As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it.  Should come back to this.

Add note to Grammar that yield expression is a special case.

Add doctest cases for SyntaxErrors raised by ast.c.

5db42c4c50 alias_for_import_name(): Dueling compiler warnings ;-) 
Squash new warnings from VC 7.1 about mixing signed and
unsigned types in comparisons.  I can see why `len` was
changed to size_t here, but don't see why `i` was also
changed.  Change `i` back to int.

51abbc7b4a Fix Armin's bug 1333982. He found it, he didn't created it :-) 
This code generated a C assertion:
        assert 1, ([s for s in x] +
                   [s for s in x])
        pass

assert was completely broken, it needed to use the proper block.
compiler_use_block() is now no longer used, so remove it.
