It is possible to have a transactional undo of object creation without
having the object in cache.
For some reason, it happens in 6.9GB FileStorage import.

Master nodes don't exchange node informations during election, this packet
handler is not implemented and so unexpected.

This fixes the inability to undo T-1 after undoing T.
For reference, this is what is done in RelStorage. It is not as restrictive
as FileStorage, but implementing the same support would/will take more
time.

The main purpose is to apply and handler after all pending requests are
satisfied and allow process answer packets of current state out of order.
This fix a bug that appears when a storage tries to get a lock on an object that
is already held by a previous transaction. Is this case the store is delayed
causing the answer packet be sent out of order (packet sequence breakage), so
unexpected from client's point of view.

Strangely, nothing in FileStorage forces a new transaction to start with a
TID higher than previous transaction. Supporting this is required for a
ZODB test to pass, so just do that - with a warning.

If EPOLLERR or EPOLLHUP is asserted, the event will be appended to
readable_fd_list, so it is useless to test their value in the second
test too.

The __undoLog() method is used by undoLog() and transactionLog() with
different parameters. When a recursive call is made, keep initial arguments
instead of always call as if it was undoLog().

When called, queued events were using the last peer message id instead of
having the good one on their connection when recalled, so answers made from
queued events was using the wrong message id.

Store does not handle conflicts (for reliability, it can only be done once
all store responses are received), so this parameter must go away.

pending store responses. Wait for them without doing conflict handling.
