2021-07-11	vm: fix invalid memory access on GC'ing uninitialized VM context	Jo-Philipp Wich
	When attempting to invoke uc_vm_free() or uc_gc() on a uc_vm_t struct that has not been initialized by uc_vm_init(), the circular double linked value list is not set up, causing the GC to read invalid memory locations when attempting to traverse the object list. Back out early when the list heads are not properly set up in order to prevent this issue. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2021-05-20	types: fix uninitialized memory on setting non-contiguous array indexes	Jo-Philipp Wich
	When ucode sets array indexes far after the array end so that a realloc() is triggered interally, the memory between the last existing array element and the newly set one was left uninitialized, leading to random segmentation faults, infinite loops or other invalid memory access symptoms.

2021-04-25	treewide: rework internal data type system	Jo-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.
