Any exception triggered by low-level code should cause a log and
connection closure before being propagated.

Fixes the following scenario (committing an object):
2 storage nodes: S1 and S2
1 replicas
- store in S1 (1)
- store in S2 (2)
- S1 answers (1) with a conflict
- client resolves the conflict, and sends to S1 (3) and S2 (4)
- S1 answers (3) with ok
- S2 answers (2) with a conflict

Old code raises because object store counter was not 0 on an object for
which a conflict was reported.
New code ignores answers notifying of a conflict if given serial is the
already-resolved conflict.
Split & extend existing tests.

There are 2 distinct kinds of timeout events:
- an unresponsive node
  This is a connection-level timeout.
  This is handled by the Timeout class, triggering pings and monitoring
  incoming data to decide when remote node is considered dead.
- a "too long" processing from an otherwise responsive node
  This is a per-request timeout.
  This is handled by the HandlerSwitcher class, triggering only
  disconnections when an answer takes too long to arrive (historical
  behaviour, not so useful when exchanging with a single-threaded peer).

Previous implementation mixed both, and had shortcomings (ping would
timeout almost immediately, it was not possible to tell which message
caused a timeout).

Update tests.

Typical case:

- Handler H1 is set
- Send request R1
- Request switch to handler H2 (delayed)
- Request switch to handler H3 (delayed)
- Receive answer A1
- H2 must be discarded and H3 applied on the connection

This fix a race condition when switching from recovery to verification
steps where NotifyLastOID packet could be handled by verification handler
instead of initialisation (storage side).

This packet handler should be dropped but it's break some functional tests,
may be due to a race condition when switching from recovery to verification.
