useful portable test case.  Maybe later...

deletion of object from list argument during callout to fileno().

builtin_module_names are always tuples.

Added hint about using clock() for benchmarks etc.
Removed non-portable strftime directives and field width, and added a
warning about non-standard features.

Tk 4.2.  The new winfo options supported are: mananger, pointerx,
pointerxy, pointery, server, viewable, visualid, visualsavailable.

Also fixed bugs in winfo_colormapfull() and winfo_containing().

1. Renamed

2. Several coding styles were being used here, owing to the multiple
   contributors.  I tried to convert everything to standard "python"
   coding style for indentation, paren and brace placement, etc.

3. There were several potential error conditions that were never being
   checked, and where I saw them, I added checks of return values,
   etc.  I'm pretty sure I got them all.

4. There were some old-style (pre PyArg_ParseTuple) argument
   extraction and these were converted to use PyArg_ParseTuple.

All changes compile and run with the new test_select.py module, at
least on my Solaris/Sparc box.

Note that since I have no idea how to test this, I didn't write a test
case.  It does seem to at least compile on my system though.

all because it can take a really long time.

that's used in other parts of this module.

nis_maps(): use PyArg_NoArgs().

Two interesting problems in nis_maplist().  First, it is possible that
clnt_create() will return NULL.  This was being caught, but no Python
error was being set.  I use clnt_spcreateerror() to generate the value
of the exception.

But why would clnt_create() fail?  It's because no server was being
found.  And why was this?  It was because nis_maplist() tried only to
get the NIS master for the first map in the aliases list, which is
passwd.byname, and guess what?  That's the one NIS map CNRI does *not*
export!  So the yp_master() call was failing to return a valid
server.  I now cycle through all the map aliases until I find a valid
master.  If not, a different exception is set.

I'm not sure this is the completely correct way to do all this, but
short of rewriting the entire nismodule.c (to expose the proper API to
Python), it should do the trick.

object pointers.  Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.

Thanks to discussions with Tim Peters.

Note that there is no test suite for this module, and I don't plan to
write one just now.

(i.e. this restores the old functionality).

Note that if a test couldn't be imported, it is just ignored (and no
warning is printed).
