Code was assuming that the keys file would contain at least one valid
key. This caused a Dynamic_array::at(0) call that lead to the crash.

 LOG-SLOW-SLAVE-STATEMENTS NOT DISPLAYED.

        These parameters were moved from the command line options to
        the system variables section. Treatment of the
        opt_log_slow_slave_statements changed to let the
        dynamic change of the variable.

    Problem was that link file (.isl) is also opened using O_DIRECT
    mode and if this fails the whole create table fails on internal
    error.

    Fixed by not using O_DIRECT on link files as they are used only
    on create table and startup and do not contain real data.
    O_DIRECT failures are successfully ignored for data files
    if O_DIRECT is not supported by file system on used
    data directory.

delete deferred events after they're executed
(otherwise they can be executed again for a sub-statement)

    BUG#15850951-DUPLICATE ERROR IN REPLICATION WITH SLAVE
    TRIGGERS AND AUTO INCREMENT

When acting as a Galera receiver node, server startup may take
more than 30 secs (the current default) as it has to wait for
SST/IST operation to complete besides spending some time doing
wsrep recovery.

Fixed by raising the default value of MYSQLD_STARTUP_TIMEOUT
to 60 secs. Also sourced /etc/default/mariadb into the init
script so that it can be used to set MYSQLD_STARTUP_TIMEOUT.

Post-fix: initialize err

Enable replication of CREATE/ALTER/DROP SERVER statements
in Galera cluster.

Allowing assigning of DECIMAL(N,0) values to INT-alike system variables.

when creating shadow nullable fields, preserve all
original field flags (because we swap flags
back and forth in not_null_fields_have_null_values())

in particular, don't do ExternalProject_Add()
that starts creating build directories for a disabled
plugin
