Fix for bug #20665 All commands supported in Stored Procedures

should work in Prepared Statements. Post-review changeset.

Problem: There are some commands which are avaiable to be executed in SP
         but cannot be prepared. This patch fixes this and makes it possible
         prepare these statements.

Changes: The commands later are made available in PS. RESET has been forbidden
         in SF/Trigger.

Solution: All current server commands where checked and those missing (see later)
          we added. Tests for all of the commands with repeated executions were
          added - testing with SP, SF and PS.

  update result
mysql-test/r/sp-dynamic.result:
  update result
mysql-test/t/ps.test:
  Add more statements, probably all currently missing which are possible in
  a SP but not preparable.
  Every statement is tested in a SP, in a SF and attempted to prepare.
mysql-test/t/ps_1general.test:
  - Enable some of the statements, which are already possible in SP.
  - 1295 -> ER_UNSUPPORTED_PS
mysql-test/t/ps_grant.test:
  Enable statements already possible in SP.
sql/sp_head.cc:
  - Reorder to keep some alphabet order.
  - Add missing SHOW_SCHEDULER_STATUS.
sql/sql_prepare.cc:
  Add possibility to prepare statements, which are already allowed in SP.
