[Tarantool-patches] [PATCH v3 8/6] schema: fix internal symbols dangling in _G

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

    
    A couple of functions were mistakenly declared as 'function'
    instead of 'local function' in schema.lua. That led to their
    presence in the global namespace.
