Removing traces of mysql_priv.h from comments and other
non-source files that were missed before.

when trying to build innodb as plugin.

The reason for the error is mismatch in mysql_temp_dir_list
declaration between mysqld.h and usage in ha_innodb.cc

Add missing MYSQL_PLUGIN_IMPORT to mysql_tmpdir_list
(variables exported by the server and used by plugin need it).

Fix tons of warnings about mismatch struct and class usage.

Tree cleaup after the last major merges in mysql-trunk:

The files sql/lex_hash.h and sql/sql_yacc.h are automatically
generated, and should not be checked in the configuration management system.
These files are now removed.
No changes are required for .bzrignore, which already listed these files
(and similar files in libmysqld/).

The file storage/perfschema/unittest/pfs_timer-t.cc did not build
after the header files refactoring affecting mysql_priv.h
The file now builds properly using sql_priv.h

Adding my_global.h first in all files using
NO_EMBEDDED_ACCESS_CHECKS.

Correcting a merge problem resulting from a changed definition
of check_some_access compared to the original patches.

Adding include to build on Windows.

Adding includes of my_global.h that seems to be necessary on Windows.

Moving an extern "C" to not cover #includes.

- Adding include/mysql/innodb_priv.h which was missing before.
- Updated .bzrignore to ignore CMake generated cruft.

Minor fixes required because of changes since patches were developed.

Fixing merge problem that causes CSV engine to misbehave.

This patch:

- Moves all definitions from the mysql_priv.h file into
  header files for the component where the variable is
  defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

experimental due to Bug 52202.

Problem: caseup_multiply and casedn_multiply members      
were not initialized for a dynamic collation, so          
UPPER() and LOWER() functions returned empty strings.      
Fix: initializing the members properly.

based replication.

Bug #49910: Behavioural change in SELECT/WHERE on YEAR(4) data type                                  
(Original patch by Sinisa Milivojevic)

The YEAR(4) value of 2000 was equal to the "bad" YEAR(4) value of 0000.                              

The get_year_value() function has been modified to not adjust bad                                    
YEAR(4) value to 2000.

comments to rpl_show_slave_running test are added to ease merging

in optimized build) 
Unlike in autotools build, innodb was compiled with 
-DUNIV_MUST_NOT_INLINE set.  this exposed what
seems to be a bug in gcc backend.

The fix is to remove extra definition.

- package some more perl scripts on Windows (mysqlhotcopy and mysqldumpslow)
- do not try to pack .map files (no more produced)
- (CMake-unrelated) fix debug build on FreeBSD, trying to use uninitialized attribute
MY_MUTEX_INIT_FAST

The problem is that when we make conditon for
grouped result const part of condition is cut off.
It happens because some parts of 'having' condition
which refer to outer join become const after
make_join_statistics. These parts may be lost
during further having condition transformation
in JOIN::exec. The fix is adding 'having'
condition check for const tables after
make_join_statistics is performed.

DBUG_SYNC_POINT has at least one strong limitation that it's not defined
on all platforms. It has issues cooperating with @@debug.
All in all its functionality is superseded by DEBUG_SYNC facility and
there is no reason to maintain the old less flexible one.

Fixed with adding debug_sync_set_action() function as a facility to set up
a sync-action in the server sources code and re-writing existing simulations
(found 3) to use it.
Couple of tests have been reworked as well.

The patch offers a pattern for setting sync-points in replication threads
where the standard DEBUG_SYNC does not suffice to reach goals.

This has been back-ported from 6.0 as the problems proved to afflict 
5.1 as well.
The fix exposed two new bugs. They were reported as follows.
      
Bug no 52174: Sometimes wrong plan when reading a MAX value 
from non-NULL index
      
Bug no 52173: Reading NULL value from non-NULL index gives wrong 
result in embedded server 
      
Both bugs taken together affect a much smaller class of queries than #47762, 
so the fix stays for now.
