Disconnect slave if duplicate event detected
...
If a duplicate event is detected the state of the slave is set
to BLRS_ERRORED and the connection is closed. That way the
duplicate event will not break the slave, and it will pick
up its state when it reconnects.

Add duplicate event detection & logging.
...
When an event is sent to a slave, we store information about the
event and who sent it, so that we can detect if the same event is
sent twice. If a duplicate event is detected, we log information
about it.

Ensure that slave->cstate contains meaningful value.
...
In blr_slave_callback the bits of slave->cstate are reset and
set as one transaction. Earlier they were reset in one and
set in another, leading to a situation where slave->cstate did
not contain a sensible value for a short period of time.
Further, it is now explicitly checked in blr_distribute_binlog_record
that slave->cstate indeed contains a meaningful value.

Unsafe position is no longer an error
...
The unsafe slave position is no longer an error and will be treated the
same way if no events are available i.e. the slaves are no longer disconnected.
The log messages now have more information such as the current committed
transaction event being processed and the number of events sent by the
current thread.

Changed behaviour for a slave requesting master_log_pos beyond binlog file size
...
Slave request for a log_pos behind binlog file size may result in a
disconnection or replication error:
if binlog file is latest one slave get disconnected otherwise an error
message is returned and replication stops

Remove file from slave
...
The binlog file is now always opened when it is needed and closed
when we are finished with it. That will remove any potential
file concurrency issues between different threads dealing with
the same slave.

some of the disconnected slaves were used when printing slave hosts.

Add notice about previous failure to unlock.

In blr_slave.c under certain conditions, two locks were not released.
That was fixed in another change, and with this change a notice will be
logged if that branch is entered. That way it will be possible to find
out whether this may have been the cause of earlier lock-ups.
