Dmitry Lenev 599457ae2c Fix for bug #58499 "DEFINER-security view selecting from 
INVOKER-security view access check wrong".

When privilege checks were done for tables used from an 
INVOKER-security view which in its turn was used from 
a DEFINER-security view connection's active security
context was incorrectly used instead of security context
with privileges of the second view's creator.

This meant that users which had enough rights to access
the DEFINER-security view and as result were supposed to 
be able successfully access it were unable to do so in 
cases when they didn't have privileges on underlying tables 
of the INVOKER-security view.

This problem was caused by the fact that for INVOKER-security
views TABLE_LIST::security_ctx member for underlying tables
were set to 0 even in cases when particular view was used from 
another DEFINER-security view. This meant that when checks of
privileges on these underlying tables was done in
setup_tables_and_check_access() active connection security 
context was used instead of context corresponding to the 
creator of caller view.

This fix addresses the problem by ensuring that underlying
tables of an INVOKER-security view inherit security context
from the view and thus correct security context is used for
privilege checks on underlying tables in cases when such view 
is used from another view with DEFINER-security.

mysql-test/r/view_grant.result:
  Added coverage for various combinations of DEFINER and
  INVOKER-security views, including test for bug #58499
  "DEFINER-security view selecting from INVOKER-security
  view access check wrong".
mysql-test/t/view_grant.test:
  Added coverage for various combinations of DEFINER and
  INVOKER-security views, including test for bug #58499
  "DEFINER-security view selecting from INVOKER-security
  view access check wrong".
sql/sql_view.cc:
  When opening a non-suid view ensure that its underlying 
  tables will get the same security context as use for
  checking privileges on the view, i.e. security context
  of view invoker. This context can be different from the
  security context which is currently active for connection 
  in cases when this non-suid view is used from a view with
  suid security. Inheriting security context in such situation
  allows correctly apply privileges of creator of suid view
  in checks for tables of non-suid view (since in this 
  situation creator/definer of suid view serves as invoker
  for non-suid view).
