lib: Add decoder functions
Split existing lua_to* functions into two functions:
- lua_decode_*: unmarshall Lua values into an existing C data structure
- lua_to*: allocate *and* unmarshall Lua values into C data structure
This allows us to mutate C data structures passed into frrscript_call,
without allocation
