            misbehave on PPC64

There was a mix of ulong and uint casts/variables which caused
incorrect value to be passed to/retrieved from max_relay_log_size
and sql_slave_skip_counter.

This mix failed to work on big-endian PPC64 where sizeof(int)= 4,
sizeof(long)= 8. E.g. session_var(thd, uint)= 1 will in fact store
0x100000000.

            chain

InnoDB mutex_exit() function calls __sync_test_and_set() to release
the lock. According to manual this function is supposed to create
"acquire" memory barrier whereas in fact we need "release" memory
barrier at mutex_exit().

The problem isn't repeatable with gcc because it creates
"acquire-release" memory barrier for __sync_test_and_set().
ATC creates just "acquire" barrier.

Fixed by creating proper barrier at mutex_exit() by using
__sync_lock_release() instead of __sync_test_and_set().

MDEV-5262, MDEV-5914, MDEV-5941, MDEV-6020: Deadlocks during parallel replication causing replication to fail.

Merge the patches into MariaDB 10.0 main.

With this patch, parallel replication will now automatically retry a
transaction that fails due to deadlock or other temporary error, same as
single-threaded replication.

We catch deadlocks with InnoDB transactions due to enforced commit order. If
T1 must commit before T2 in parallel replication and T1 ends up waiting for T2
inside InnoDB, we kill T2 and retry it later to resolve the deadlock
automatically.

MDEV-5262, MDEV-5914, MDEV-5941, MDEV-6020: Deadlocks during parallel replication causing replication to fail.

Fix a bug discovered in Buildbot valgrind. The logic in checking for slave
init thread completion was reversed, so depending on thread scheduling server
startup could hang.

Also add another variant of SSL valgrind suppression, needed for different
library version.

MDEV-6435: Assertion `m_status == DA_ERROR' failed in Diagnostics_area::sql_errno() with parallel replication

When a MyISAM query is killed midway, the query is logged to the binlog marked
with the error.

The slave does not attempt to run the query, but aborts with a suitable error
message in the error log for the DBA to act on.

In this case, the parallel replication code would check the sql_errno() code,
even no my_error() had been set. In debug builds, this causes an assertion.

Fixed the code to check that we actually have an error set before querying for
an error code.

For this patch in 10.0, we do not introduce a new public storage engine API,
we just fix the InnoDB/XtraDB issues. In 10.1, we will make a better public
API that can be used for all storage engines (MDEV-6429).

Eliminate the background thread that did deadlock kills asynchroneously.
Instead, we ensure that the InnoDB/XtraDB code can handle doing the kill from
inside the deadlock detection code (when thd_report_wait_for() needs to kill a
later thread to resolve a deadlock).

(We preserve the part of the original patch that introduces dedicated mutex
and condition for the slave init thread, to remove the abuse of
LOCK_thread_count for start/stop synchronisation of the slave init thread).

The sql_slave_skip_counter is important to be able to recover replication from
certain errors. Often, an appropriate solution is to set
sql_slave_skip_counter to skip over a problem event. But setting
sql_slave_skip_counter produced an error in GTID mode, with a suggestion to
instead set @@gtid_slave_pos to point past the problem event. This however is
not always possible; for example, in case of an INCIDENT event, that event
does not have any GTID to assign to @@gtid_slave_pos.

With this patch, sql_slave_skip_counter now works in GTID mode the same was as
in non-GTID mode. When set, that many initial events are skipped when the SQL
thread starts, plus as many extra events are needed to completely skip any
partially skipped event group. The GTID position is updated to point past the
skipped event(s).

MDEV-6344: mysqldump issues FLUSH TABLES, which gets written into binlog and replicated

Add a --gtid option (for compatibility, the original behaviour is preserved
when --gtid is not used).

With --gtid, --master-data and --dump-slave output the GTID position (the
old-style file/offset position is still output, but commented out). Also, a
CHANGE MASTER TO master_use_gtid=slave_pos is output to ensure a provisioned
slave is configured in GTID, as requested.

Without --gtid, the GTID position is still output, if available, but commented
out.

Also fix MDEV-6344, to avoid FLUSH TABLES getting into the binlog. Otherwise a
mysqldump on a slave server will silently inject a GTID which does not exist
on the master, which is highly undesirable.

Also fix an incorrect error handling around obtaining binlog position with
--master-data (was probably unlikely to trigger in most cases).

- Add a Sort_priority_queue_sorts status variable.

- Make log_slow_verbosity print "Priority_queue: (Yes|No)" into the slow query log.
  (but we do not add a correspoding column to P_S.*statement* tables).

Analysis: For some reason table stats for a table pointed from a index 
is not initialized. Added additional warning output on this situation
and table stats initialization. This is better than asserting.

Comment out unknown options in SHOW CREATE TABLE unless IGNORE_BAD_TABLE_OPTIONS is used

Reject huge frms at CREATE TABLE, not when it - successfully written - is being opened.
Also raise the frm size limit from 256K to 512K

Analysis: sync array output function, should make sure that all
used pointers are valid before using them.

Merge revision 4225 from lp:maria/5.5.

Follow-up patch. The original patch added an extra argument to the
rli->report() function, however it was forgotten to adjust the calls
accordingly in a few places.

This patch updates the remaining calls as needed. In files log_event_old.cc
and rpl_record_old.cc, it just adds NULL, since this is only for old event
formats from ancient master servers, which would not have any GTID information
to add to the error messages in any case.

than with InnoDB plugin

Fix: os0file.h in XtraDB had OS_AIO_N_PENDING_IOS_PER_THREAD 256
when on InnoDB it is OS_AIO_N_PENDING_IOS_PER_THREAD 32. Changed
XtraDB also to use 32.

then can't ALTER TABLE any more.

Fix for InnoDB storage engine.

ALTER TABLE any more.

        Tests were merged.
        As the implementation is different, the 'internal debugging' part
        was not merged, only a stub for it created.
