bsddb3Storage becomes BDBStorage
Full becomes BDBFullStorage
Minimal becomes BDBMinimalStorage

Removing MinimalReplicated.py, Packless.py, and base.py

- start_zeo_server():  Only quote the command line args for Windows;
  these break the tests on Linux, which would only need the quoting if
  the shell were involved: it's not for os.spawnve().

Merge to HEAD: The ZEO unit tests and wo_pcgi.py didn't run on Windows if the path to the python executable included a space.

storage's artifacts.  Some tests expect to reconnect in read-only mode
to a previously created storage.

Starts near the end of the file and reads forward, looking for a
complete snapshot.  If it doesn't find one, move farther from the end
and repeat.

XXX This approach does N**2 reads, where N is the number of times we
need to move further back and retry.  When we move backwards, we
double the distance from the end of the file.

This processes the whole file from the beginning collecting info about
active / blocked transactions.  This version is preliminary because it
needs to start at the end and backup until it has enough information.

tpc_begin() doesn't return anything anyway.
Rename transaction to txn to make lines shorter.

Should the deadline by checked inside this final loop waiting for
wrappers to finish?

Get ZClasses working.  (Tested this time.)
Add some more comments and add XDECREFs to avoid leaks.
Remove redundant check of ExtensionClass in get_class().
Apparent fix for ZClass persistent_id problem.

shutdown_zeo_server(): Same thing here, but notice that on Windows,
the recv() can raise an ECONNRESET, which I believe we can just
ignore.  (Will test this with Tim shortly.)

Instead use self.new_dest() to get a new destination storage.

Added an XXX to memind me.

:).

Because we're worried about backward compatibility, for now we'll
rebind asyncore.loop() to a function that prints a warning and then
calls loop().  Eventually we'll take this away so you have to call
ThreadedAsync.loop() explicitly.

through the sneakily rebound asyncore.loop().

rename UnixTests to FileStorageTests, and add a simple BDBTests class
to use Berkeley Full storage.

Rewrite to use the new forker module api.

WindowsTests: Removed.

rename UnixConnectionTests to FileStorageConnectionTests, and add a
simple BDBConnectionTests class to use Berkeley Full storage.

WindowsConnectionTests: Removed.

DummyDB.invalidate(): Add **kws since some of the tests try to use
keyword arguments.

Removed redundant keyword arguments from various openClientStorage()
calls.

makes little sense to call the server script `winserver.py'.  That's
gone now, in favor of this zeoserver.py script.  Changes include:

main(): Accept a -C option pointing to a temp file containing a
ZConfig storage section.  This reads the file and creates the so
described storage, then removes the temp config file.  It creates an
administrative server which opens an `admin' port which is used to
os._exit() this process, with the following protocol.  The first time
the admin port is connected to, an ack character is sent from
zeoserver.  This is necessary to coordinate the tests so that they are
assured the server is running and responding before it tries to do
more.  Otherwise, some tests were vulnerable to timing bugs where the
shutdown connect happened before the server was ready to accept them.

The second connect exits the server process just like before.  Copious
log entries are written.

This script also cleans up after the storages are closed, by calling
the storage's .cleanup() method if it exists (FileStorage and the
Berkeley storages both implement this method).
