Turn the 'abort_on_warning' on for assigning value to fields.

fix it only for local operations.

first add mroonga plugin (MYSQL_ADD_PLUGIN) then add dependent
targets (add_subdirectory(groonga))

first add tokudb plugin (MYSQL_ADD_PLUGIN) then add dependent

remove ~15 years old print_lock_error() function, use
handler::print_error() instead

The workaround is not needed anymore - mariadb requires bison 2.x.

And removing all __attribute__ in sql_yacc.yy breaks
new DBUG_ENTER.

when func1 calls func2 from DBUG_RETURN, dbug shows the trace as
| > func1
| < func1
| > func2
| < func2
because DBUG_LEAVE happens before func2(). Change that to invoke
DBUG_LEAVE when the local variable goes out of scope. This uses
gcc specific __attribute__((cleanup)).

Don't mark the SEQUENCE engine as XA-capable. The engine never
registers itself for any transaction, so it doesn't matter
whether it is XA-capable or not. The only effect of being
"XA-capable" is breaking the "number of XA-capable engines"
check of TC_LOG_MMAP.

remove the test that depended on the current cracklib dictionary

because buildbot config invokes BUILD/compile-solaris-amd64
with the --extra-args=--without-plugin-innodb argument, but
BUILD/compile-solaris-amd64 doesn't take arguments and doesn't
invoke configure.pl, so this extra-args is lost.

Problem is that FLUSH TABLES WITH READ LOCK first blocks threads from
starting new commits, then waits for running commits to complete. But
in-order parallel replication needs commits to happen in a particular
order, so this can easily deadlock.

To fix this problem, this patch introduces a way to temporarily pause
the parallel replication worker threads. Before starting FTWRL, we let
all worker threads complete in-progress transactions, and then
wait. Then we proceed to take the global read lock. Once the lock is
obtained, we unpause the worker threads. Now commits are blocked from
starting by the global read lock, so the deadlock will no longer occur.

Preparation patch, moving the GCO wait into a separate function, in
preparation for adding a separate wait phase for FLUSH TABLES WITH
READ LOCK.

Before, the Seconds_behind_master was updated already when an event
was queued for a worker thread to execute later. This might lead users
to interpret a low value as the slave being almost up to date with the
master, while in reality there might still be lots and lots of events
still queued up waiting to be applied by the slave.

While querying INFORMATION SCHEMA, check for a table's engine
only used table name, but not schema name; so, if there were different
rows with the same table name, a wrong one could be retrieved.
The result of the check affected the decision whether the contents
of the table should be dumped, and whether a DELAYED option can be used.
Fixed by adding a clause for table_schema to the query.

Using __attribute__  needs my_attribute.h include

(Simple speedup)

(We where using stage_copying_to_tmp_table twice)

Not printing the value" with binlog-row-image=minimal"

Merged Rows_log_event::print_verbose_one_row() and log_event_print_value()
with MySQL 5.7
Added flush after writing of Table_map_log_event() to fix wrong order of
lines in output. This causes a lot of changes in some test results.

- XA
- Transaction_context_event (used by MysQL group replication)
- View change event (used by MysQL group replication)

Fixed failure in tests when running optimized code
- Some assert() was using code that had to be executed
Fixed copying of some uninitialized data (fixed valgrind warning)

(Makes TABLE a bit smaller)

changes in query execution plans.
Fixed by introducing table->rpl_write_set which holds which columns should
be stored in the binary log.

Other things:
- Removed some not needed references to read_set and write_set to make
  code really changing read_set and write_set easier to read
  (in opt_range.cc)
- Added error handling of failed unpack_current_row()
- Added missing call to mark_columns_needed_for_insert() for DELAYED INSERT
- Removed not used functions in_read_set() and in_write_set()
- In rpl_record.cc, removed not used variable error

Removed old not needed code withing #if
Changed 0x%lx to %p

The bitmap implementation defines two template Bitmap classes. One
optimized for 64-bit (default) wide bitmaps while the other is used for
all other widths.

In order to optimize the computations, Bitmap<64> class has defined its
own member functions for bitmap operations, the other one, however,
relies on mysys' bitmap implementation (mysys/my_bitmap.c).

Issue 1:
In case of non 64-bit Bitmap class, intersect() wrongly reset the
received bitmap while initialising a new local bitmap structure
(bitmap_init() clears the bitmap buffer) thus, the received bitmap was
getting cleared.

Fixed by initializing the local bitmap structure by using a temporary
buffer and later copying the received bitmap to the initialised bitmap
structure.

Issue 2:
The non 64-bit Bitmap class had the Iterator missing which caused
compilation failure.

Also added a cmake variable to hold the MAX_INDEXES value when supplied
from the command prompt. (eg. cmake .. -DMAX_INDEXES=128U). Checks have
been put in place to trigger build failure if MAX_INDEXES value is
greater than 128.

Test modifications:
* Introduced include/have_max_indexes_[64|128].inc to facilitate
skipping of tests for which the output differs with different
MAX_INDEXES.

* Introduced include/max_indexes.inc which would get modified by cmake
to reflect the MAX_INDEXES value used to build the server. This file
simply sets an mtr variable '$max_indexes' to show the MAX_INDEXES
value, which will then be consumed by the above introduced include file.

* Some tests (portions), dependent on MAX_INDEXES value, have been moved
to separate test files.
