0207e6b066 More tests for ASST3.2 
Added 2 new sbrktests, one to test a huge sbrk with only touch a few pages (shouldn't crash),
and another to make sure pages are getting freed when the breakpoint moves down. Also, added
a stacktest that checks that 4M stacks are supported and pages are allocated on-demand.

388e6388a9 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.

194f76ef70 The "huge positive" number being tested wasn't big enough. Now using a number that would 
cause the heap to bleed into the stack.

b488b7dcea Added a test.h file for userland. 
Currently, this file has tsay() and nsay(), which are atomic vararg print operations
that are loud or quiet (respectively) during automated testing. These are used
throughout userland when output might get intermingled.

16bfdcf406 Added new line before printing secured messages. For quint/triple tests, the secured message 
might print on a progress line, which makes test161 fail.

only loud during automated testing.

eede850f54 The km4 thread was checking the correct magic value, but printing the one on the first page. 
The test result is correct, but might look like it is failing when it shouldn't.

78265c6da4 Set leaderboard to false for ASST3 coremap target. We'll work on aggregating multi-part targets, but for now, don't show subparts. 
Also, explicitly set userland to false.

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.

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.
