Remove the unused code (from previous commit)

Added new client tests (EXPLAIN + DECIMAL conv)

into mysql.r18.ru:/usr/home/ram/work/mysql-4.1

like number-to-string-convertion-result, now 
takes current database character set, instead of
thread character set. This makes it easy to be
SQL99 conformant and 4.0 compatible.

Item->thd_charset() is renamed to Item->default_charset()
as old name doesn't describe its nature anymore.

  -- To take care of .zip and .tar
  -- Initialization of 'data' directory without any host dependancy data
  -- Incorporate all changes from Monty

  Produce an error when a field collation and charset are not compatible

SELECT latin1_expr COLLATE anpther_charset_collation

so that it has fetched the most from the master's binlog before the master
accidently dies. SCRUM task #756.

Added options reconnect/enable-reconnect/disable-reconnect/skip-reconnect to the 'mysql' command-line client.
Disabling can be safer when the server silently dies & restarts.
This is for SCRUM task #727.

  Typo fix.

  Portability fix. GetLongPathName is not supported by Windows95.

Added GeometryCollection type.

  Fix for coercibility of function

  Charset conversion function changes coercibility to IMPLICIT

  _charset cast changes coercibility to implicit
item_strfunc.cc:
  Collation cast change coercibility to EXPLICIT

   Coercibility, initial stage
item_func.h:
  Coercibility, initial stage

  Added new tests for better coverage of
  min/max optimization code.
func_group.test:
  Added new tests for better coverage of 
  min/max optimization code.
opt_sum.cc:
  Fixed wrong previous manual merge.
  Fixed bugs concerning fields used in min/max
  functions for which there are conditions of
  the form field=const.

Fixed bug in RAND() usage in mysqlbinlog

  set names binary  didn't work
  ,

  Two separate functions charset() and collatio()
item_strfunc.h:
  Two separate functions charset() and collation()

into hundin.mysql.fi:/home/igor/dev/mysql-4.1

  Now all text fields convert data into proper charset before storing

into hundin.mysql.fi:/home/igor/dev/mysql-4.1

  Added tests for extended max/min optimization
opt_sum.cc:
  Extended min/max optimization

  Insert constants with an explicit character set
ctype_many.result:
  Fix according test change

  rename len -> length, to look in common style
