Added a workaround for shortcomings in the OSA support: there can be class/property conflicts and passing classes as arguments doesn't work. The package now seems to work.

- use unidb compression for the unicodedata module.  on Windows,
  the new unidatabase module is 120k, down from nearly 600k.

xml.sax: Fix parse and parseString not to rely on ExpatParser
         Greatly simplify import logic by using __import__
saxutils: Support Unicode strings and files as parameters to

Tiny bug fix to expatreader.py (endDocument was only called after errors).

db_185.h has renamed that function to __db185_open, which it does in DB 3.1.
So don't check whether the function is in -ldb.

The earlier code assumed "protocol=host;protocol=host;..." or "host",
but Windows may also use "protocol=host" (just one entry), as well as
"protocol://host".  This code needs some more work, so I'll leave the
bug open for now.

Bug fixes to XMLFilterBase (wrong ignorableWhitespace signature and
did not inherit set*Handler methods from XMLReader.)

tuple instead two arguments.

'spawnv' now, so we check for 'fork' first.

exec*() family of functions.

"xml.parsers.expat.error", so it will reflect the public name of the
exception rather than the internal name.

Also change some of the initialization to use the new PyModule_Add*()
convenience functions.

the module "xml.parsers.expat".

This closes SourceForge bug #115146.

I fixed the specific complaint but left the (many) large issues untouched.
See the (very long) bug report discussion for why:

Note that while I left the interface to the undocumented public API function
PyFloat_FromString alone, its 2nd argument is useless.  From a comment block
in the code:

RED_FLAG 22-Sep-2000 tim
PyFloat_FromString's pend argument is braindead.  Prior to this RED_FLAG,

1.  If v was a regular string, *pend was set to point to its terminating
    null byte.  That's useless (the caller can find that without any
    help from this function!).

2.  If v was a Unicode string, or an object convertible to a character
    buffer, *pend was set to point into stack trash (the auto temp
    vector holding the character buffer).  That was downright dangerous.

Since we can't change the interface of a public API function, pend is
still supported but now *officially* useless:  if pend is not NULL,
*pend is set to NULL.

This closes SourceForge patch #101233.

Add three new convenience functions to the PyModule_*() family:
PyModule_AddObject(), PyModule_AddIntConstant(), PyModule_AddStringConstant().

This closes SourceForge patch #101233.
