7f3f686b1a 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.

8380115efa Added new kmalloc test (km5) that tests various coremap properties. Also, km1-km4 were 
cleaned up for test161.

25a1d7debc 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.

c9c9e50155 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

44d53d9306 Fixed a bug in bad_waitpid.c 
The comments for this particular test suggest that the parent should
attempt waiting on itself. However, the code makes the parent wait
on its child. Fixed.

eb7ad5609d Make forktest fail if waitpid() fails 
Previously, forktest would only warn if the calls to waitpid()
returned errors. Now, forktest terminates on the first error.

196bb3b684 Now using static buffers (and protecting with a semaphore) for kernel secprintf. 
We have to do this because we need secure output in kmalloc.

2cb47cb4c8 Removed all instances of crash_prog() 
crash_prog was introduced to force-crash a userspace program
since _exit may not yet be implemented. However, the new versions
of OS161 already have the exact same logic as crash_prog in stdlib/exit.
