The admin commands in question are:
> OPTIMIZE
> REPAIR
> ANALYZE
For LOCAL or NO_WRITE_TO_BINLOG invocations of these commands, ie
OPTIMIZE LOCAL TABLE <t1>
they are not binlogged as expected.
Also, in addition, they are not executed under TOI.
Hence, they are not propagated to other nodes.
The effect is same as that of wsrep_on=0.
Also added tests for this.
A WSREP_DEBUG for wsrep_register_hton has also been added.
The galera_flush_local test has also been updated for verifying that effects
of NO_WRITE_TO_BINLOG / LOCAL are equivalent to wsrep_on=0 from wsrep
perspective.

- Fixes query cache so that it is aware of wsrep_sync_wait.
Query cache would return (possibly stale) results to the
client, regardless of the value of wsrep_sync_wait.
- Includes the test case that reproduced the issue.
Fixes a deadlock between applier and its victim transaction.
The deadlock would manifest when a BF victim was waiting for some lock
and was signaled to rollback, and the same time its wait
timeout expired. In such cases the victim would return from
lock_wait_suspend_thread() with error DB_LOCK_WAIT_TIMEOUT, as opposed to
DB_DEADLOCK. As a result only the last statement of the victim would rollback,
and eventually it would deadlock with the applier.
- Removes useless call to wsrep_xid_init() in wsrep_apply_events().
Transaction's xid is already initialized at that point.
- Adds call to wsrep_set_SE_checkpoint() for committing TOI events
in the applier side.
- Includes test case that reproduced the issue.
- Moves call wsrep_free_status() to THD::cleanup_after_query().
Wsrep status variables were previously freed only on SHOW STATUS.
- Removes valgrind suppression from mysql-test/valgrind.
"#include <math.h>" has "#define isfinite(X) ..."
while "#include <cmath>" does "#undef isfinite"
in -std=c++11 mode <cmath> is included, we need a workaround
to provide a usable isfinite()

Federated/spider/connect engines or replication threads connecting to other host
with empty user name may crash mysqld.
This is addition to original patch, which adds a test case and amends a macro.
