locks all rows (BUG #3300). When using innobase_locks_unsafe_for_binlog
option InnoDB does not take locks for those rows which do not
belong to the result set or werent changed by the query. This fix removes
unnecessary locks also from SELECT and DELETE queries.

Crop fruits of copy-paste programming: pre-caching of stored functions
wasn't performed for prepared statements just because implementation

_all_ versions. It tries to remove "Docs/Images/Makefile*" as part of the actions to
correct bug number 6350. If the source tree does not contain a dummy file matching
that pattern, this "rm" will fail, and so "Bootstrap" will fail.
The "Makefile.am" introduced with this changeset is identical to the one that will
arrive in the 5.0 tree when "joerg:1.2057" is propagated from 4.0 via 4.1 to here,
so this separate introduction here is just to allow "Bootstraps" in the meantime.

  - No RESTICT|CASCADE in DROP SP (since it's not implemented)
  - Added optional "noise" to FETCH: [[NEXT] FROM]
  - At least one statement required in all block constructs except BEGIN-END
    (where zero is allowed)

FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT
Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete
