Added thread_wait_for_count() which allows the menu to wait for all (new) threads to

exit before continuing. We need this for khu testing because we have to make sure
cleanup is done before getting the used byte count.

The km4 thread was checking the correct magic value, but printing the one on the first page.

Updated km4 to write to, and check, each page allocated in the multi-page allocation.
...
This should find cases where students ignore npages and just allocate one page, which
would previously work.

Changed kheap_getused so that it doesn't double-count the pages it's using for

subpage allocation. We run into problems in determining memory leaks due to
kmalloc framgmentation, which can happen because of delayed thread cleanup.

Updated forkbomb to better detect success
...
Previously, we were relying on subpage allocator failing to signal
that forkbomb was succeeding. However, there are cases where the
subpage allocator never fails but the test is still progressing fine.
This commit moves the secure print into forkbomb itself and changes
the test constraints to ensure that forkbomb runs for a certain amount
of time without crashing
