Fixed.

Done.

Hm, I finally understood the difference between them.

Done.

=============================================================

This patch introduces a new system space to persist check
constraints. The format of the new system space is

_ck_constraint (space id = 364)
[<space id> UINT, <constraint name> STR,
 <is_deferred>BOOL, <language>STR], <code>STR

A CK constraint is local for a space, so every pair
<space id, CK name> is unique
(it is also the PK in the _ck_constraint space).

After insertion into this space, a new instance describing check
constraint is created. Check constraint holds an exspression AST.
While space features some check constraints, it isn't allowed to
be dropped. The :drop() space method firstly deletes all check
constraints and then removes an entry from the _space.

Because the space alter, the index alter and the space truncate
operations cause space recreation process, a new
RebuildCkConstrains object is introduced. This alter object
compiles a new ck constraint object, replaces and removes
an existent instances atomically (but if the assembly of some
ck constraint object fails, nothing is changed).
In fact, in scope of this patch we don't really need to recreate
a ck_constraint object in such situations (it is enough to patch
space_def pointer in AST tree like we did it before, but we are
going to recompile a VDBE that represents ck constraint in
further patches, and that operation is not safe).

The main motivation for these changes is an ability to support
ADD CHECK CONSTRAINT operation in the future. CK constraints are
easier to manage as self-sustained objects: such change is
managed with atomic insertion(unlike the current architecture).

Finally, the xfer optimization is disabled now if some space have
ck constraints. In following patches this xfer optimisation
becomes impossible, so there is no reason to rewrite this code
now.

Needed for #3691
