Problem: Segmentation fault in add_group_and_distinct_keys() when accessing
field of what is assumed to be an Item_field object.

Cause: In case of views, the item added to list by is_indexed_agg_distinct() 
was not of type Item_field, but Item_ref.

Resolution:  Add the real Item_field object, the one referred to by 
Item_ref object, to the list, instead.

mysql-test/r/count_distinct.result:
  Results for test case for Bug#51980.
mysql-test/t/count_distinct.test:
  Test case for Bug#51980.
  Table needs to contain at least two rows to avoid const table optimization.
sql/sql_select.cc:
  Make sure it is the actual Item_field object that is pushed to the out_args
  list of is_indexed_agg_distinct(), and not Item_ref objects.

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.

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.

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)

- (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.


mysql-test/r/having.result:
  test case
mysql-test/t/having.test:
  test result
sql/sql_select.cc:
  added 'having' condition check for const tables
  after make_join_statistics is performed.
