* Fixes some more holes in the ref tracker
The reference tracker was failing to check null keyed assoc list entries, along with being unable to check both
lists in a list(list() = list()) pair
This resolves that, and adds some new logic to the unit test to check for this sort of thing
* Seperates the ref tracking unit test into 6 subtasks as requested
* Ref Tracking: Revengance
Fixes reference tracking ignoring self references due to a poorly thought out tick checking system.
Fixes reference tracking ignoring the contents of assoc lists
Makes the reference tracking printouts actually describe what list the ref is in, rather then just saying "list"
Adds REFERENCE_TRACKING_DEBUG, a define which toggles tracking info for the ref tracking procs, which allows for
oversight on how the proc is working
Allows for direct calls of qdel_and_find_ref_if_fail(), makes it use ref rather then REF(), fixing it breaking
for mobs. (Ditto for the qdel hint which does the same thing)
Moves REAGENTS_TESTING out of the reftracking define block
Makes unit tests define REFERENCE_TRACKING, REFERENCE_TRACKING_DEBUG, and FIND_REF_NO_CHECK_TICK
Adds a unit test that sanity checks the reference finder proc
* Uses 514's map_cpu var when it's available
* Uses auxtools for the debugger, to supply cross verison compatibility
* Nukes extools reference tracking, reinstates the old ref tracking system
About The Pull Request
Adds extools-powered reference tracking. Includes a couple procs that retrieve the back and forward references of a datum - Back references let you see what is referencing your object and potentially preventing it from garbage collecting, and forward ones show you what your object in turn references. Also made a cool GUI to inspect and follow these references.
The tracking adds some overhead to all variable sets and list operations. Init time is increased by ~15%. I haven't actually benched it so it might impact the actual game less.
Why It's Good For The Game
no lagging caused by hard dels scanning the entire planet (once coders fix them)
