onStoreTimeout is called by poll thread, which causes a new local_var to be
implicitly created with a new queue (specific to poll thread, which isn't
supposed to have one).
To know the queue that should receive AnswerHasLock, reuse the one
registered to dispatcher to receive AnswerStoreObject.

except in that special case.

This fixes cases where a thread is expecting some answer from queue, and
a packet gets forgotten, as it would block until next expected packet
arrives (if there is no next packet, it will wait forever).

SendPartitionTable packet was sent between Ask and Answer PartitionTable
packets, as notifications. In this case, the only purpose of the 'Answer'
was to check that the partition table was filled. The 'Ask' allowed also
to request a part of the partitions but was not used and redundant with
AskPartitionList for neoctl.

This commit include the following work:
- The partition table is always send in one packet.
- The full partition table is always requested with AskPartitionTable
- The full partition table is notified with SendPartitionTable
- Client node process the answer in the bootstrap handler.
- Admin can receive answer *and* notifications for the partition table.
- Move the log calls to the pt.py module
- Add pt.getRowList() to factorise the code.
- Build partition table packets out of the loop when possible
- Always load inconditionnaly the partition table in generic pt.py
-

This fix an issue where a client was notified down, dropped from node
manager then detected as disconnected: the node was not found.

Store deadlocks might happen when the order in which storage nodes receive
object data (and hence, grant write lock for those objects) is not
consistent among clients. So when a store timeouts, it might be because
another transaction got the store lock on this storage and object, while
it might wait for locks we got on other storage nodes or objects.
In doubt, report a conflict to abort current transaction in hope for the
other transaction to succeed.

As we don't (and must not, otherwise it would deadlock) take a write lock
on a storage node when detecting a conflict, it is possible that multiple
conflicts get successively reported for a single object in a single
transaction. To solve this, client must tolerate multiple conflict for a
single object. The last resolved conflict being sent to all storage nodes,
transaction data will be consistent at tpc_finish.

- conflict_serial_dict and resolved_conflict_serial_dict become
  multivalued (sets instead of scalar)
- each resolution only resolve conflict with highest serial if greater
  than previous resolutions for the same object
  NOTE: this assumes that ("r" being conflict resolution method, "Tn"
  being the TID on which object is based, and "Cn" being a conflict with
  transaction n) when r(T0, C1) generates T1 but triggers C2,
    r(T0, C1) + r(T1, C2) == r(T0, C2)
