2021-04-25treewide: rework internal data type systemJo-Philipp Wich
Instead of relying on json_object values internally, use custom types to represent the different ucode value types which brings a number of advantages compared to the previous approach: - Due to the use of tagged pointers, small integer, string and bool values can be stored directly in the pointer addresses, vastly reducing required heap memory - Ability to create circular data structures such as `let o; o = { test: o };` - Ability to register custom `tostring()` function through prototypes - Initial mark/sweep GC implementation to tear down circular object graphs on VM deinit The change also paves the way for possible future extensions such as constant variables and meta methods for custom ressource types.
