f2771d5ad8 Remove obsolete message
The warning that a schema already exists is obsolete as mapped tables are
now always opened instead of being reused. This causes the schema checks
to be done for each mapped table.

Removing a server from readconnroute caused the connection to be closed if
it was a master server.

5f4db64ac7 Better timing for switchover, check slaves for IO/SQL errors
Time elapsed is now properly tracked during a switchover. After slave
redirection, an event is added to the master. Then, the slaves are queried
repeatedly until they advance to the newest event. I/O and SQL errors are
also detected.

e5d9ca4af8 Check if master reference is disabled
If a Backend is closed, the associated DCB is no longer valid. This needs

3f78dbc923 Improve avrorouter assertion output
When an assertion fails due to an overflow of the event buffer, all
processed values for that event are dumped.

This commit also enables the assertions even for non-debug builds which
should speed up the elimination process for bugs in the avrorouter. The
overhead of doing this is minimal as the output is already gathered for
the INFO level logging.

047c08f577 MXS-1588: Wait on all slaves during switchover
During switchover, MASTER_GTID_WAIT is now called on all slaves. This causes
switchover to complete slower than before but is safer if log_slave_updates
is not on on the new master server. Also, read_only is disabled on the
demoted server if waiting on slaves or promotion fails. This should
effectively cancel the failover for the old master.

f5484a1011 MXS-1576: Add purge command to avrorouter
The `purge` command can be used to reset the conversion
process. Currently, executing the `purge` module command and restarting
MaxScale is the only correct way to reset the conversion process.

a86b81824f MXS-1575: Add extra debug assertions
Added more debug assertions to JSON serialization of the Avro schema. Also
checked that the column count for the TABLE_CREATE object matches that of
the TABLE_MAP object.

200657e2f6 Pre-load binlogrouter modules for the test
The test loads multiple modules in one call so we have to pre-load them
one by one to make sure that they are all present regardless of the
locations where the individual modules were built.

8d15256d70 MXS-1539: Add asynchronous authenticator capability

core that all entry points for it support asynchronous usage.

bacc11d28e MXS-1516: Validate the connection on each query
A subset of the checks done at connection creation time need to be done at
query routing time. This guarantees that the connection is closed if the
server no longer qualifies as a valid candidate.

Added teset case that checks that a change in the replication topology
correctly breaks the connection.

95983ddaf4 Fix unit test failures
When the unit tests were run without installing the libraries in their
final locations, the loading of the modules would fail. Using locations
relative to the build directory allows unit testing without having to
install the libraries.

a46881c0cc MXS-1585: Check that the master refence is in use
The check for the current master backend did not see if the backend was
actually in use. This would be the case when the backend would be
originally in use but would be later disabled.

71d3009cd6 Make a deep copy of queued queries
If a shallow copy of the buffer is made, any modifications that are made
to the data after it has been queued will affect the queued query of the
LocalClient.

A copy-on-write mechanism would save the relatively expensive process of
copying the data but since the LocalClient is not often used, it is not
the most critical performance problem.

d4f9cb661f MXS-1587 Rename mysqlmon to mariadbmon
'mysqlmon' is still accepted but 'mariadbmon' is loaded instead.
This is done at runtime instead of e.g. by using a symbolic link,
so that a warning can be logged.

The warning is logged and the translation of the module name is
made by the code that loads the modules so that it's easy to do
the same thing for other modules as well.

In a subsequent commit the documentation is updated.

3ccd6eed28 MXS-1588 Fix switchover
Change the ordering of the two flushes such that FLUSH LOGS comes last.
This seems to make sure gtid:s are updated to newest values before
the MASTER_GTID_WAIT-call. Without this fix, switchover does complete
succesfully, but some of the slaves may not be able to replicate due to
not having same events as new master. Exact reason for this still unclear.
