[Tarantool-patches] [PATCH 0/3] Fix upgrade from 2.1 sequence

[Vladislav Shpilevoy]

The patchset fixes inability to upgrade from 2.1 if there is an
automatically generated sequence. The problem was that upgrade
tried to update a tuple in _space_sequence in-place, calling
space:update() method. But it was not properly supported for
_space_sequence. The patchset turns it into delete + insert, and
bans updates for this space.
