Ensure that privileges are tested properly for multi-table-updates. 

Now one need only SELECT privilege for tables that are only read in
UPDATE statements with many tables. (Bug #2377).


sql/sql_acl.cc:
  Comment cleanup
sql/sql_parse.cc:
  Merged duplicate code.
  Removed some outdated 'tables->db' tests.
  Check privileges for multi-updates properly (Bug #2377)
sql/sql_show.cc:
  Remove disabled code
sql/sql_update.cc:
  Ensure that privileges are tested properly for multi-table-updates
tests/grant.pl:
  Added more tests
tests/grant.res:
  updated results
