check_equality() finds equalities among field items. It checks input items
to be Item_fields thus skipping view's fields, which are represented by
Item_direct_view_ref. Because of this index wasn't applied in all cases
it can be.

To fix this problem check_equality() now takes real item of
Item_direct_view_ref, except outer view refs (with depended_from set).

  allow select into outfile from I_S tables
  it is enough to add FILE_ACL for I_S tables only to 'check_table_access' function
  as we use 'any_db' for 'check_access' function in places where FILE_ACL is required

  Corrected platform name output

  Reintroduced --machine
  Better sh compatibility, "for i ; do" is not portable
