tests more precise to aid test debugging.

Changed the default blob-cache-size-check size to 10%.

Changed the algorithm for deciding the target for blob cache
reduction. Now the target is

blob-cache-size * (100 - blob-cache-size-check)/100

testing a storage. :)

Made it possible to opt out of recovery tests.

use "import time" so we can mess with time.time in tests.

non-shared blob directories, you can set a target cache size and the
cache will periodically be reduced to the target size.

To enable blob cache management, a new IBlobStorage method,
openCommittedBlobFile has been added.

defeat FileStorage's index optimization.

data for reading as an ordinary file, rather than as a blob file.
The ordinary file may be used outside the current transaction and
even after the blob's database connection has been closed.

to create configuration files first. This is primarily useful for
exploration and development.

software.

Added code to select different client and server stubs and input
handlers depening on whether the Z309 or earlier protocols are used.

ZODB 3.8 clients can now talk to ZODB 3.9 servers and the other way
around.

on windows that makes subproccess unhappy.

In the doctest support, save the pids along with adminaddrs and, when
we shutdown a server, wait for it to stop with os.waitpid. This is to
avoid a race where we end up trying and failing to delete the server's
log files before the server has closed them.
