[tarantool-patches] [PATCH 0/3] sql: move column's default value to Tarantool's core

[Kirill Yukhin]

This patches-set consists of 3 almost independent patches:
 1. It adds a nullable field to space _schema, which will make it easier
    to use from within SQL engine.
 2. [tiny] Remove couple of dead functions from SQL engine.
 3. [main] Moves DEFAULT values, both string and compiled AST to Tarantool's
    core. New routine which will allow to compile SQL-context free expressions
    was introduced. Compiled AST is stored inside space_def and allocated
    using single top-most malloc().

NB1: It should be mentioned, that duplication routines for expressions are not elegant
enough to do single malloc(), it allocates nodes on demand and this may and will
be refactored. Issue to be submitted.

NB2: Handle `struct sqlite3 *` use used only for regacy memory allocation. And should
be removed from all API parameters, after we'll choose right allocator and emply it.
Another issue to be submitted.
