I dropped all the object checks from the patch since there is still a lot
to be done. I will finish with the checks taking your comments into
account and send a separate patch.

Checking for create privilege ignores ownership, since when creating an
object there can't be a create privilege on the object itself. So you
may only
create indices (even in your own spaces!) only if you have create
privilege on
universe or on entity space. Which, in turn, leads to you being able to
create
indices in any space (even in one you don't own).
I discussed it whith Georgy and we decided to check for alter privilege
on index
creation, and check for alter OR drop privilege on dropping an index,
since dropping an index is altering a space, and dropping a space
(which requires dropping all its indices) should only require a drop
privilege.

AFAIU, it was added here to let user change his own name and password.
I left the old variant unnchanged for now, but we can grant the user alter
privilege upon itself on its creation, as soon as single object access
checks
are implemented.

Removed this part from the patch, will add lacking entities (role,
collation)
and send a separate patch.
