Transaction.begin() didn't do anything.

begin() is supposed to abort the current transaction, but
Transaction.begin() did not.  Calling begin() on a transaction
*manager* worked fine, and is the intended way to do a begin()
in 3.3.  But calling begin() on a Transaction object is still
very easy to do (e.g., the older get_transaction().begin()
spelling still works), and shouldn't be a subtle disaster.

It's possible that an oid is referenced despite never being
defined (well, it's not *supposed* to be possible ...).

automated test.  There were so many oddities getting that test
to pass, and so much consequent fiddling of other code, that I
don't intend to merge this to the 3.3 branch.  Also moved to
current Python CVS doctest.py, because the test really needs
the +ELLIPSIS option (tids vary across runs).

started with a pickle GLOBAL opcode.  Curiously, it handled the
case of starting with a MARK GLOBAL opcode *sequence* fine.

FileIterator.next():  the code for reading the user, description,
and extension fields from a transaction was fatally confused,
usually reading them out of the object pickle by mistake.  This
caused several tools to display binary gibberish.

Forward port from Zope 2.7 branch.

analyze_rec():  This produced spurious "len of unsized object" messages
when a data record had a backpointer instead of a pickle.  Repaired.

analyze(), analyze_trans():  Simplified overly elaborate iteration code.

Just changing what we're calling the next release.

Please don't do that:  ZODB changes need to be done in the ZODB
project.  Checkins to Zope3 have no effect on ZODB in reality.

These are preliminary 3.3c1 release changes.

Improve thread-death error reporting in tests.

Reworked the way some of the ZEO tests use threads, so that unittest is
more likely to notice the real cause of a failure (which usually occurs in
a thread), and less likely to latch on to spurious problems resulting from
the real failure.

Detail:  The TestThread class got the (unittest) test case as an argument,
and remembered it.  If the run() method saw the thread die with an
exception, it called testcase.fail() with the formatted exception.  But
this can't work as apparently intended:  unittest's fail() raises an
AssertionError then, and the piece of unittest running the test expects
to catch that exception and append the message to the result object's
list of failures.  But the piece of unittest running the test isn't on
*this* thread's call stack!  It's on the main thread's call stack.
So unittest simply raised an exception that wasn't noticed by anything,
and the thread died then, leaving a traceback somewhere in the middle
of the output.  unittest didn't know anything about that, and sometimes
thought the test passed despite the thread failure.

Alas, when a thread dies like this it's also got a decent chance of
leaving things in a state where the test's final checking code can't
succeed, but the checking code doesn't know the thread died either,
and spurious unittest failures and errors could get reported then.

Reworked things so that only the main thread ever tries to tell
unittest that a test failed.  A TestThread remembers an exception-
death now, but doesn't report it until the main thread tries to join
it.  This way unittest knows the test failed; records and reports
the true cause of failure; and, because tests generally join all their
threads before doing their final checking, unittest stops the test
before final checking if a thread death occurred, and so there's
less chance of seeing reports of spurious errors and failures.
