The new "substr in str" feature masked the error.

The line, "from _random import Random as CoreGenerator", fools the test
code which expects CoreGenerator.__name__ to be "CoreGenerator" instead
of "Random".

This is for (slightly) more consistency with the OSS ioctl names
(READ_DEVMASK, READ_RECMASK, READ_STEREODEVS).

Also make sure the C function names correspond more closely to the
Python method names for mixer methods.

into the core DLL, since it's not much code and lots of stuff uses
it (e.g., try getting a tempfile name without it).

Guido has in mind an easier way for users to code this stuff, but the
only tests we have now are for fixed-offset tzinfo classes, and this
stuff is extremely delicate in the endcases (read the new test code
for why:  there are holes in time <wink>).

M PyShell.py

1. PyShell Rev 1.39, EditorWindow Rev 1.37 fix was not handling a
   multiline prompt.
2. The same fix introduced a bug where hitting <enter> at a previous
   prompt-only line would copy the prompt to the iomark.
3. Move the setting of sys.ps1 earlier, into PyShell.main(), to allow
   this code to work before a shell is started up.
4. If cursor is on the input line in the prompt, and you hit <enter>,
   process the line instead of complaining.
5. If line has no stdin range (this includes the last line before shell
   restart) strip any prompt before recalling.

Also, made some whitespace cleanup.

is a demand, that could be added at a later date.

This can cause core dumps when Python runs.  Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions.  This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.
