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

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.

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All in all its functionality is superseded by DEBUG_SYNC facility and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.





mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test:
  rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based;
  a pattern of usage DEBUG_SYNC for replication testing is provided.

  results are changed.
mysql-test/suite/rpl/t/rpl_get_master_version_and_clock.test:
  rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based;
  limiting the test to run only with MIXED binlog-format as the test last
  some 10 secs sensitively contributing to the total of tests run.
mysql-test/suite/rpl/t/rpl_show_slave_running.test:
  rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based.
sql/debug_sync.cc:
  adding debug_sync_set_action() function as a facility to set up
  a sync-action in the server sources code.
sql/debug_sync.h:
  externalizing debug_sync_set_action().
sql/item_func.cc:
  purging sources from DBUG_SYNC_POINT.
sql/mysql_priv.h:
  purging sources from DBUG_SYNC_POINT.
sql/slave.cc:
  rewriting failure simulations to base on DEBUG_SYNC rather than GET_LOCK()-based DBUG_SYNC_POINT.
sql/sql_repl.cc:
  removing an orphan failure simulation line because no counterpart in tests existing.

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.

Optimizer erroneously translated LEFT JOIN into INNER JOIN.
It leads to cutting rows with NULL right side. It happens
because Item_row uses not_null_tables() method form the
base(Item) class and does not calculate 'null tables'
properly. The fix is adding calculation of 'not null tables'
to Item_row.


mysql-test/r/join_outer.result:
  test result
mysql-test/t/join_outer.test:
  test case
sql/item_row.cc:
  adding calculation of 'not null tables' to Item_row.
sql/item_row.h:
  adding calculation of 'not null tables' to Item_row.

The crash happens because of discrepancy between values of
conts_tables and join->const_table_map(make_join_statisctics).
Calculation of conts_tables used condition with
HA_STATS_RECORDS_IS_EXACT flag check. Calculation of
join->const_table_map does not use this flag check.
In case of MERGE table without union with index
the table does not become const table and
thus join_read_const_table() is not called
for the table. join->const_table_map supposes
this table is const and later in make_join_select
this table is used for making&calculation const
condition. As table record buffer is not populated
it leads to crash.
The fix is adding a check if an engine supports
HA_STATS_RECORDS_IS_EXACT flag before updating
join->const_table_map.


mysql-test/r/merge.result:
  test result
mysql-test/t/merge.test:

All numeric operators and functions on integer, floating point 
and DECIMAL values now throw an 'out of range' error rather 
than returning an incorrect value or NULL,  when the result is 
out of supported range for the corresponding data type. 
 
Some test cases in the test suite had to be updated 
accordingly either because the test case itself relied on a 
value returned in case of a numeric overflow, or because a 
numeric overflow was the root cause of the corresponding bugs. 
The latter tests are no longer relevant, since the expressions 
used to trigger the corresponding bugs are not valid anymore. 
However, such test cases have been adjusted and kept "for the 
record".

  link)

           for InnoDB
            
The class Field_bit_as_char stores the metadata for the
field incorrecly because bytes_in_rec and bit_len are set
to (field_length + 7 ) / 8 and 0 respectively, while
Field_bit has the correct values field_length / 8 and
field_length % 8.
            
Solved the problem by re-computing the values for the
metadata based on the field_length instead of using the
bytes_in_rec and bit_len variables.
            
To handle compatibility with old server, a table map
flag was added to indicate that the bit computation is
exact. If the flag is clear, the slave computes the
number of bytes required to store the bit field and
compares that instead, effectively allowing replication
*without conversion* from any field length that require
the same number of bytes to store.

  Removing flags parameter from table map constructor
  since it is not used and does not have to be exposed.

  Adding flag to denote that bit length for bit field type
  is exact and not potentially rounded to even bytes.
sql/rpl_utility.cc:
  Adding fields to table_def to store table map flags.
sql/rpl_utility.h:
  Removing obsolete comment and adding flags to store

   definition at engine

If a single ALTER TABLE contains both DROP INDEX and ADD INDEX using 
the same index name (a.k.a. index modification) we need to disable 
in-place alter table because we can't ask the storage engine to have 
two copies of the index with the same name even temporarily (if we 
first do the ADD INDEX and then DROP INDEX) and we can't modify 
indexes that are needed by e.g. foreign keys if we first do 
DROP INDEX and then ADD INDEX.
Fixed the problem by disabling in-place ALTER TABLE for these cases.
