Add tests/serial/netsplit_merge•••This tests the 'merging' case where channel state from
all servers with equal channel creation timestamp are
merged together, eg banlist, etc.
Will be expanded later to include +e, +I, regular modes, ..
Improve speed of m.expect() massively if timeout=xx is used, so•••in situations where the autosyncer is turned off (m.sync=0).
We now try to match first and only if that does not succeed
then we call asyncore.loop().
Performance is needed for the new netsplit tests.
