This constructor is called automatically during function recovery
by prototype defined in snapshot. Thus all functions are
initialized in a one place: in on_replace_dd_func trigger.
I like this concept because it is uniform and all implementation-dependent
details (like the completion of the function definition initialization) are hidden
in the corresponding module (sql/func.c).
Technically we may skip a function cache entry creation for SQL_BUILTIN
tuple type in on_replace_dd_func trigger, to perform the whole preparements
during Tarantool initialization. This require to distinguish SQL_BUILTIN entries
and other types in trigger and this is not cool, I believe.
Finally, a current approach enforces keeping snapshot will all built in definitions
in actual state.
