[PATCH 0/2] Remove 1.7 privilege compatibility mode

[PATCH 0/2] Remove 1.7 privilege compatibility mode

[Serge Petrenko]

We assume that if user has READ + WRITE on an object, it also has
CREATE + ALTER + DROP on an object. This was needed for compatibility
with old versions which didn't have CREATE, ALTER, DROP ACLs.
Now it's time to remove this compatibility mode.

The first patch removes this compatibility mode.

The second patch adds an upgrade script to automatically
grant CREATE, ALTER, DROP to everyone with READ and WRITE
on upgrade to 2.1.0

[PATCH 1/2] box: remove compatibility mode for privileges

[Serge Petrenko]

Before version 1.7.7 there were no CREATE or ALTER privileges.
READ+WRITE permitted object creation and altering.
In 1.10 CREATE and ALTER privileges were introduced together with a
compatibility mode in access_check_ddl() which assumed user had CREATE
and ALTER if it had READ and WRITE on a respective object.
Now its time for us to remove this compatibility mode.

Part of #3539
