RefC backend improvements (#2425)
* RefC backend improvements

1. OnCollect had the wrong number of arguments. The code creator expects
   3 arguments, but onCollect in prim.h expected 4 arguments. The first of which
   was an erased arguments. That is now fixed.

2. OnCollect did not call `newReference` when creating a new reference to the pointer
   and the freeing function

3. OnCollect and OnCollectAny still had a spurious printf statement

Those issues have been fixed, the test case can be found in
  tests/refc/garbageCollect

4. The IORef mechanism expects that the %World token will be passed around
   consistently. This is not the case. States in Control.App make use of
   IORefs, but the function created from Control.App.prim_app_bind
   had the world token erased to NULL.
   Now, IORefs are managed using a global variable,
   IORef_Storage * global_IORef_Storage;
   referenced in cBackend.h, defined in the created .c file, and set to NULL
   in main();

5. While multithreading and forking is still not supported, compiling a program
   that makes use of Control.App demands a C implementation of prim_fork.
   Files support/refc/threads.c and support/refc/threads.h provide a
   dummy implementation for it, so that Control.App programs compile and run.

A test for these 2 issues is given in tests/refc/issue2424
