[tarantool-patches] [PATCH v3 0/9] sql: uniform SQL and Lua functions subsystem

[Kirill Shcherbatov <kshcherbatov@tarantool.org>]

This patchset reworks SQL functions subsystem. Previously Tarantool's
SQL used an own FuncDef function representation and corresponding
FuncDef cache. Replacing it with Tarantool's uniform function
representation makes possible to call any function on any supported
language in SQL.

Branch: http://github.com/tarantool/tarantool/tree/kshch/gh-4182-persistent-functions
Issue: https://github.com/tarantool/tarantool/issues/2233

  sql: rework SQL_FUNC_COUNT flag semantics
  sql: rename OP_Function to OP_BuiltinFunction
  sql: remove SQL_FUNC_SLOCHNG flag
  sql: get rid of FuncDef function hash
