- Add new DML op: Batch, which allows
using multiple dml operations in one
CAS request
- If request has too many dml operations,
the batch will be splitted into multiple
batches, so that each batch can be stored
in raft log

- Update sbroad submodule to commit with
grant/revoke procedure support
- Use existing mechanisms for grant/revoke
ACL opcodes for grant/revoke procedure
implementation
- Add integration tests
- Valid combinations:

all procedures: grant/revoke create/execute/drop
specific procedure: grant/revoke execute/drop

- Syntax:

grant create procedure to alice option(timeout=3)
grant execute procedure on "spam"(int) to "alex"
grant drop procedure on foo to bob
revoke drop procedure on foo from bob

This commit introduces:
 * statement and portal storages;
 * statements with parameter oids;
 * portal encoding;
 * interactive portals;

Portal encoding defines in which format (binary or text) columns
are returned.

Interactive portals allow to limit the number of rows returned from
execute method. Other rows can be extracted by calling execute again
on the same portal.
