Task #627 : user variables' names are now case-insensitive :

@test=@"tEsT"=@`teST` etc. Tests updated.
Note that the patch to sql_class.cc does not use HASH_CASE_INSENSITIVE as did the one which I sent for review. This is because meanwhile HASH_CASE_INSENSITIVE has disappeared (since cset 1.1504.1.6).


mysql-test/r/variables.result:
  updated test
mysql-test/t/variables.test:
  updated test
sql/sql_class.cc:
  Task #627 : user variables' names are now case-insensitive :
  @test=@"tEsT"=@`teST` etc.
