Initial commit of work pertaining to switching the Windows build from Berkeley DB 4.4.20 to 4.7.25. Note that I've deprecated the standalone '_bsddb44.vcproj' in lieu of adding the sources in a separate folder to the _bsddb project. This was a conscious decision and actually makes everything far more easier to manage. With this approach, entire test suite passed straight off the bat. Well, almost -- the timeout in bsddb/test/test_replication.py needed bumping up a little -- 2 seconds was too short. 10 seconds seems to be fine for me, but I'll make sure Jesus verifies. More documentation to come once I've been able to test out this approach on the buildbots (hence keeping the changes in a separate branch for now).

Bump Berkeley DB version from 4.4.20 to 4.7.25.
........
when database changes size during iteration.
It now behaves like a dictionary, the next attempt to get a value from
the iterator after the database has changed size will raise a RuntimeError.
stuff in and clean it up afterwards regardless of the result.
* Get rid of duplicate list of test modules to run, they're maintained
within test_all now.
* Print the BerkeleyDB version to stderr when running test_bsddb3 to
help buildbot problem diagnosis.
not appear to be a new bug, its just that the test coverage went up
recently exposing it. (I verified that by testing this test code on
an older Modules/_bsddb.c)
run the test simultaneously. The simplest thing I found that worked
on both Windows and Unix was to use the PID. It's unique so should be
sufficient. This should prevent many of the spurious failures of
the automated tests since they run as different users.
Also cleanup the directory consistenly in the tearDown methods.
It would be nice if someone ensured that the directories are always
created with a consistent name.
NULL bytes it would cause the database all sorts of problems in the future
leading to very strange random failures and corrupt dbtables.bsdTableDb dbs.
keyword argument whenever possible to avoid bugs and confusion. (dbtables.py
line 447 self.db.get using txn as a non-keyword was an actual bug due to this)
string key (and probably a few other situations with string keys).
This was reported with a patch as pybsddb sourceforge bug 1708868 by
jjjhhhlll at gmail.
The problem is that _DB_get_type() can't be called without the GIL
because it calls a bunch of PyErr_* APIs when an error occurs.
There were no other cases in this file that it was called without the GIL.
Removing the BEGIN/END THREAD around _DB_get_type() made everything work.
Will backport.
now works reliably. It has been updated to use automatic BerkeleyDB
deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
database calls that would previously deadlock. [SF python bug #775414]
aborts the db transaction safely when a modifier callback fails.
Fixes SF python patch/bug #1408584.
Also cleans up the bsddb.dbtables docstrings since thats the only
documentation that exists for that unadvertised module. (people
really should really just use sqlite3)
