Merge current trunk into p3yk. This includes the PyNumber_Index API change,
which unfortunately means the errors from the bytes type change somewhat:
bytes([300]) still raises a ValueError, but bytes([10**100]) now raises a
TypeError (either that, or bytes(1.0) also raises a ValueError --
PyNumber_AsSsize_t() can only raise one type of exception.)

Whitespace normalization broke test_cgi, because a line

blank. Changed the string from raw to regular, and forced

test_PyThreadState_SetAsyncExc(): This is failing on some
64-bit boxes. I have no idea what the ctypes docs mean
by "integers", and blind-guessing here that it intended to
mean the signed C "int" type, in which case perhaps I can
repair this by feeding the thread id argument to type
ctypes.c_long().
Also made the worker thread daemonic, so it doesn't hang
Python shutdown if the test continues to fail.

Even though _Py_Mangle() isn't truly public anyone can call it and
there was no verification that privateobj was a PyString. If it wasn't
a string, this could have allowed a NULL pointer to creep in below and crash.
I wonder if this should be PyString_CheckExact? Must identifiers be strings
or can they be subclasses?

test_signal: Signal handling on the Tru64 buildbot
appears to be utterly insane. Plug some theoretical
insecurities in the test script:
- Verify that the SIGALRM handler was actually installed.
- Don't call alarm() before the handler is installed.
- Move everything that can fail inside the try/finally,
so the test cleans up after itself more often.
- Try sending all the expected signals in
force_test_exit(), not just SIGALRM. Since that was
fixed to actually send SIGALRM (instead of invisibly
dying with an AttributeError), we've seen that sending
SIGALRM alone does not stop this from hanging.
- Move the "kill the child" business into the finally
clause, so the child doesn't survive test failure
to send SIGALRM to other tests later (there are also
baffling SIGALRM-related failures in test_socket).
- Cancel the alarm in the finally clause -- if the
test dies early, we again don't want SIGALRM showing
up to confuse a later test.
Alas, this still relies on timing luck wrt the spawned
script that sends the test signals, but it's hard to see
how waiting for seconds can so often be so unlucky.
test_threadedsignals: curiously, this test never fails
on Tru64, but doesn't normally signal SIGALRM. Anyway,
fixed an obvious (but probably inconsequential) logic
error.

Ah, fudge. One of the prints here actually "shouldn't be"

after conversion.

Fix a couple of bugs exposed by the new __index__ code. The 64-bit buildbots
were failing due to inappropriate clipping of numbers larger than 2**31
with new-style classes. (typeobject.c) In reviewing the code for classic
classes, there were 2 problems. Any negative value return could be returned.
Always return -1 if there was an error. Also make the checks similar
with the new-style classes. I believe this is correct for 32 and 64 bit
boxes, including Windows64.
Add a test of classic classes too.

ctypes instances no longer have the internal and undocumented

the type's stgdict.
In the 'from_param' class methods, try the _as_parameter_ attribute if
other conversions are not possible.
This makes the documented _as_parameter_ mechanism work as intended.
