#449043 supporting __future__ in simulated shells
in support of PEP 264.

Much has changed from the patch version:
+ Repaired bad hex constant for nested_scopes.
+ Defined symbolic CO_xxx names so global search will find these uses.
+ Made the exported list of feature names explicit, instead of abusing
  __all__ for this purpose (and redefined __all__ accordingly).
+ Added gross .compiler_flag verification to test___future__.py, and
  reworked it a little to make use of the newly exported explicit list
  of feature names.

is pickled as a global must now exist by the name under which it is
pickled, otherwise the pickling fails.  Previously, such things would
fail on unpickling, or unpickle as the wrong global object.  I'm
hoping that this won't break existing code that is playing tricks with
this.

I need a volunteer to do this for cPickle too.

- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions
- disables unicode literals, and the builtin functions
- add the types.StringTypes list
- remove Unicode literals from most tests.

expression.  This is needed for certain servers that (in violation of
the standard) don't return the parentheses in the response.

This fixes SF bug #441712 by Henrik Weber (not exactly using his
patch).

local module tables (the lists of modules documented within a chapter,
inserted at the beginning of the chapter).  If this is not done here,
the text is not part of the resulting documents when latex2html does the
processing normally.

This fixes a little bit more of SF bug #451556.

the class dict).  Anything but a nonnegative int in either place is
*ignored* (before, a non-Boolean was an error).  The default is still
static -- in a comparative test, Jeremy's Tools/compiler package ran
twice as slow (compiling itself) using dynamic as the default.  (The
static version, which requires a few tweaks to avoid modifying class
variables, runs at about the same speed as the classic version.)

slot_tp_descr_get(): this also needed fallback behavior.

slot_tp_getattro(): remove a debug fprintf() call.

more tabs that XEmacs Makefile mode found suspicious.

- Change PY_VERSION (but not the numeric versions) to "2.2a1+".

class has a correct repr().

streamlined a bit.

instancemethod_descr_get(): don't bind an unbound method of a class
that's not a base class of the argument class.

when an unbound method of class A is stored as a class variable of
class B, and class B is *not* a subclass of class A, that method
should *not* get bound to B instances.

subclasses type, one that doesn't (the latter isn't fully functional
yet).

the metatype passed in as an argument.  This prevents infinite
recursion when a metatype written in Python calls type.__new__() as a
"super" call.

Also tweaked some comments.

Also removed senseless Windows comment.

This closes SF bug #451630.

assigned to a class variable and then accessed via an instance, it
should not be rebound.

test_descr.py:methods(): test for the condition above.

    calculate it on the fly.  This way even modules with long package
    names get an accurate repr instead of a truncated one.  The extra
    malloc/free cost shouldn't be a problem in a repr function.

If genpluginprojects is called from fullbuild we set the Python source directory to be the same as fullbuild uses (in stead of using the default sys.prefix). This fixes an issue Mark Day raised that you can't use fullbuild with one Python installation to build another one.

Remove pointless comment

    I have no way of testing this.

+ test_compare.  While None compares less than anything else, it's not
  always the case that None has the smallest id().
+ test_descr.  The output of %p (pointer) formats varies across platforms.
  In particular, on Windows it doesn't produce a leading "0x".

    the "#ifdef MS_WINDOWS" to "#ifdef SELECT_USES_HEAP" and by
    setting SELECT_USES_HEAP when FD_SETSIZE > 1024.

    The indirection seems useful since this subtly changes the path
    that "normal" Windows programs take (where Timmie sez FD_SETSIZE =
    512).  If that's a problem for Windows, he has only one place to
    change.

parameter, but did not.  This was found because it can create failures
elsewhere based on the presence of mime.types files in some common locations
the module searches by default.

(I will be writing a test for this module shortly!)

optimization for dynamic classes.  If __getattr__ is not found as an
attribute on the type, slot_tp_getattro replaces itself with
PyObject_GenericGetAttr.  This means you can't add a __getattr__
method to a class after the fact -- but you can still *change* a
__getattr__ method into a different one.

(A similar restriction exists for classic classes.)

have to do "from PIL import Image" instead of "import Image".

performance changes since the affected functions are not expected to be
used frequently, but reduces the volume of code.
