bc4a456758 MDEV-452 Add full support for auto-initialized/updated timestamp and datetime
Generalized support for auto-updated and/or auto-initialized timestamp
and datetime columns. This patch is a reimplementation of MySQL's
"WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to
ease future merges, this implementation reused few function and variable
names from MySQL's patch, however the implementation is quite different.

TODO:
The only unresolved problem in this patch is the semantics of LOAD DATA for
TIMESTAMP and DATETIME columns in the cases when there are missing or NULL
columns. I couldn't fully comprehend the logic behind MySQL's behavior and
its relationship with their own documentation, so I left the results to be
more consistent with all other LOAD cases.

The problematic test cases can be seen by running the test file function_defaults,
and observing the test case differences. Those were left on purpose for discussion.

288eeb3a31 MDEV-232: Remove one fsync() from commit phase.
Introduce a new storage engine API method commit_checkpoint_request().
This is used to replace the fsync() at the end of every storage engine
commit with a single fsync() when a binlog is rotated.

Binlog rotation is now done during group commit instead of being
delayed until unlog(), removing some server stall and avoiding an
expensive lock/unlock of LOCK_log inside unlog().

47929af5e0 MDEV-450: Deadlock between starting a slave and reading system variables
Starting the SQL thread might deadlock with reading the values of the
replication filtering options.

The deadlock is due to a lock order violation when the variables are
read or set. For example, reading replicate_ignore_table first
acquires LOCK_global_system_variables in sys_var::value_ptr and later
acquires LOCK_active_mi in Sys_var_rpl_filter::global_value_ptr. This
violates the order established when starting a SQL thread, where
LOCK_active_mi is acquired before start_slave, and ends up creating a
thread (handle_slave_sql) that allocates a THD handle whose
constructor acquires LOCK_global_system_variables in THD::init.

The solution is to unlock LOCK_global_system_variables before the
replication filtering options are set or read. This way the lock
order is preserved and the data being read/set is still protected
given that it acquires LOCK_active_mi.

0697ee265f MDEV-181: XID crash recovery across binlog boundaries
Keep track of how many pending XIDs (transactions that are prepared in
storage engine and written into binlog, but not yet durably committed
on disk in the engine) there are in each binlog.

When the count of one binlog drops to zero, write a new binlog checkpoint
event, telling which is the oldest binlog with pending XIDs.

When doing XA recovery after a crash, check the last binlog checkpoint
event, and scan all binlog files from that point onwards for XIDs that
must be committed if found in prepared state inside engine.

Remove the code in binlog rotation that waits for all prepared XIDs to
be committed before writing a new binlog file (this is no longer necessary
when recovery can scan multiple binlog files).

Add function to replace arbitrary event with dummy event.

Add code which uses this to fix the bug that enabling row_annotate events

Add that slaves set a variable @mariadb_slave_capability to inform the
master in a robust way about which events it can, and cannot, handle.

Add tests.

5e13093df1 MDEV-359: Server crash when SET GLOBAL rpl_semi_sync_master_enabled = OFF
The semisync code does a fast-but-unsafe check for enabled or not without lock,
followed by a slow-but-safe check under lock. However, if the slow check failed,
the code still referenced not valid data (in an assert() expression), causing a
crash.

Fixed by not running the incorrect assert when semisync is disabled.

1605b7f68f BUG#12400221 - 60926: BINARY LOG EVENTS LARGER THAN MAX_ALLOWED_PACKET
Problem
========
            
SQL statements close to the size of max_allowed_packet produce binary
log events larger than max_allowed_packet.
              
The reason why this failure is occuring is because the event length is
more than the total size of the max_allowed_packet + max_event_header
length. Now since the event length exceeds this size master Dump
thread is unable to send the packet on to the slave.
                      
That can happen e.g with row-based replication in Update_rows event.
            
Fix
====
          
The problem was fixed by increasing the max_allowed_packet for the
slave's threads (IO/SQL) by increasing it to 1GB.
This is done using the new server option included which is used to
regulate the max_allowed_packet of the slave thread (IO/SQL).
This causes the large packets to be received by the slave and apply
it successfully.

sql/log_event.h:
  Added the new option in the log_event.h file.
sql/mysqld.cc:
  Added a new option to the server.
sql/slave.cc:
  Increasing the session max_allowed_packet to a large value ,
  i.e. not taking global(max_allowed) into consideration, for the slave's threads.

cdaae1692b BUG#13979418: SHOW BINLOG EVENTS MAY CRASH THE SERVER
The function mysql_show_binlog_events has a local stack variable
'LOG_INFO linfo;', which is assigned to thd->current_linfo, however
this variable goes out of scope and is destroyed before clean
thd->current_linfo.

The problem is solved by moving 'LOG_INFO linfo;' to function scope.

49e484c8cd BUG#11754117 incorrect logging of INSERT into auto-increment
BUG#11761686 insert_id event is not filtered.
  
Two issues are covered.
  
INSERT into autoincrement field which is not the first part in the composed primary key 
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
  
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
  
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
  
Fixed with deferring their execution until the parent query.
