68e755b1c2 core: Allocate threads on demand, not on scheduler startup 
API change: rust_kernel::create_scheduler() or
rust_scheduler::rust_scheduler() respecitevly now take ownership of the
launch factory argument, it is needed to create new threads on demand.

Also renames rustrt::sched_threads() to rustrt::rust_sched_threads() for
consistency. Added rustrt::rust_max_sched_threads() to return the
maximal number of scheduled threads of the current scheduler.

Fixes #3493.

3f0d207b32 gc: Add stack walker for new garbage collector. 
Safe points are exported in a per-module list via the crate map. A C
runtime call walks the crate map at startup and aggregates the list of
safe points for the program.

Currently the GC doesn't actually deallocate memory on malloc and
free. Adding the GC at this stage is primarily of testing value.

The GC does attempt to clean up exchange heap and stack-allocated
resource on failure.

A result of this patch is that the user now needs to be careful about
what code they write in destructors, because the GC and/or failure
cleanup may need to call destructors. Specifically, calls to malloc
are considered unsafe and may result in infinite loops or segfaults.

5e36a99794 Refactor trans to replace lvalue and friends with Datum. 
Also:
- report illegal move/ref combos whether or not ref comes first
- commented out fix for #3387, too restrictive and causes an ICE
