            returns unexpected result

If:
  1. a table has a not nullable BIT column c1 with a length
     shorter than 8 bits and some additional not nullable
     columns c2 etc, and
  2. the WHERE clause is like: (c1 = constant) AND c2 ...,
the SELECT query returns unexpected result set.


The server stores BIT columns in a tricky way to save disk
space: if column's bit length is not divisible by 8, the
server places reminder bits among the null bits at the start
of a record. The rest bytes are stored in the record itself,
and Field::ptr points to these rest bytes.

However if a bit length of the whole column is less than 8,
there are no remaining bytes, and there is nothing to store in
the record at its regular place. In this case Field::ptr points
to bytes actually occupied by the next column in a record.
If both columns (BIT and the next column) are NOT NULL,
the Field::eq function incorrectly deduces that this is the
same column, so query transformation/equal item elimination
code (see build_equal_items_for_cond) may mix these columns
and damage conditions containing references to them.

  Added test case for bug #37799.
mysql-test/t/type_bit.test:
  Added test case for bug #37799.
sql/field.h:
  1. The Field::eq function has been modified to take types of
  comparing columns into account to distinguish between BIT and
  not BIT columns referencing the same bytes in a record.
  
  2. Unnecessary type comparison has been removed from the
  Field_bit::eq function (moved to Field::eq).

      
When switching to indexed ORDER BY we must be sure to reset the index read
flag if we are switching from a covering index to non-covering.

used causes server crash.
      
When the loose index scan access method is used values of aggregated functions
are precomputed by it. Aggregation of such functions shouldn't be performed
in this case and functions should be treated as normal ones.
The create_tmp_table function wasn't taking this into account and this led to
a crash if a query has MIN/MAX aggregate functions and employs temporary table
and loose index scan.
Now the JOIN::exec and the create_tmp_table functions treat MIN/MAX aggregate
functions as normal ones when the loose index scan is used.

            tables open

When executing a DROP DATABASE statement in ROW mode and having temporary
tables open at the same time, the existance of temporary tables prevent
the server from switching back to row mode after temporarily switching to
statement mode to handle the logging of the statement.

Fixed the problem by removing the code to switch to statement mode and added
code to temporarily disable the binary log while dropping the objects in the
database.


mysql-test/extra/binlog_tests/database.test:
  Added test to ensure that DROP DATABASE does not affect the replication mode.
sql/sql_db.cc:
  Removed code that clears the current_stmt_binlog_row_based flag.
  Added code to disable the binary log while dropping the objects

Updated partition_symlink since different error behavior

  Fix for embedded

Typo fixed.
No test case as we actually don't use rtree_get_first() 
and rtree_get_next() at present.

Problem: data consistency check (maximum record length) for a correct
MyISAM table with CHECKSUM=1 and ROW_FORMAT=DYNAMIC option 
may fail due to wrong inner MyISAM parameter. In result we may 
have the table marked as 'corrupted'. 

Fix: properly set MyISAM maximum record length parameter.


myisam/mi_create.c:
  Fix for bug #37310: 'on update CURRENT_TIMESTAMP' option crashes the table
  
  Use HA_OPTION_PACK_RECORD instead of HA_PACK_RECORD (typo?) 
  calculating packed record length.
