Fix for BUG#1495: Evaluate items before setting a local variable with SELECT INTO.

Browse Source 
Also copy and restore order_list and group_list for selects in SPs.


mysql-test/r/sp.result:
  Test for BUG#1495, and an additional cursor test.
mysql-test/t/sp.test:
  Test for BUG#1495, and an additional cursor test.
sql/sp_head.cc:
  Fix BUG#1495: renamed eval_func_item() into sp_eval_func_item() and made it
  non-static.
  Also need to copy and restore order_list and group_list pointers before and
  after execution of a substatement. (Which means these must always be properly
  initialized for all queries.)

  Fix BUG#1495: Evaluate and set a local variable (for SELECT INTO).
sql/sp_rcontext.h:

  order_list and group_list must be initialized in select_lex for all queries,
  to make SP sub statement execution work.

  Type needed for setting local variables.

  Need a copy of the Item* pointer when executing sub-statements in SPs. (Since
