Lua functions managed by Tarantool are called 'persistent'.
They are stored in snapshoot and are available after server
restart. No regular Lua functions, nor C functions can't be
'persistent' because they depend on non-only snapshot environment
(libc, global variables etc.).
Some restrictions must be accounted writing such routines:
1. only limited set of Lua functions and modules are available:
-assert -error -pairs -ipairs -next -pcall -xpcall -type
-print -select -string -tonumber -tostring -unpack -math -utf8;
2. global variables are forbidden.
Persistent Lua functions are exported in box.schema.func.persistent
folder. They may be called via .call in exported object or via
netbox:call.
In scope of this patch, refactored func module API: in case of
persistent Lua function update may be insecure operation, so
we need a machinery to transactionally update the object.
