Rename unicodedata.db* to unicodedata.ucd*

Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.

happy with the output as-is.  This incidentally also
gets rid of "an extra" blank line at the end of the output
block that probably wasn't intended (although it doesn't
matter one way or the other).

Tools/scripts/svneol.py: added the .sln and .vcproj extensions because these are text files.
Ran svneol.py over the source tree.

Settings for 64-bit Windows are missing.

I've left in the 64-bit warnings to remind me to port ctypes to Py_ssize_t.

mindlessly from time to time, checking in whatever it
happens to do ;-)

Based on a patch from Hye-Shik Chang.

missing PyObject_Del()'s, simplify some code by using Py_BuildValue()
instead of creating a tuple with items manually, stop clobbering builtin
exceptions in a few places, and guard against NULL-returning functions some
more.

This fixes 117 of the 780 (!?!#%@#$!!) reference leaks in test_bsddb3. I
ain't not done yet, although this review of 5kloc was just the easy part.

an error code, this let `self` leak.  This is a disaster
on Windows, since `self` already points to a newly-opened
file object, and it was impossible for Python code to
close the thing since the only reference to it was in a
blob of leaked C memory.

test_hotshot test_bad_sys_path():  This new test provoked
the C bug above.  This test passed, but left an open
"@test" file behind, which caused a massive cascade of
bogus test failures in later, unrelated tests on Windows.
Changed the test code to remove the @test file it leaves
behind, which relies on the change above to close that
file first.
