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.

e0fc622e00 Added progress functions that print '.'. There are versions that are always loud or 
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.

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

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.

1b99c0e18f Refactored ksecprintf -> secprintf. Secure code is now all in common libtest161. 
This library gets linked in by default in userland, and the common files are
included in the kernel.

01f2d3ea2c Added ksecprintf for securely printing messages from the kernel. 
If SECRET_TESTING is defined, the function will compute and print
a salt value and the hmac/sha256 hash of the message, which can be
verified from the test161 server.

a97b1c80b2 Added sha256 hash function and hmac functions (with and without salt) to the kernel 
and userspace.

In userspace, this is accessed through #include <secure.h>
In the kernel, this is access through #include <kern/secure.h>

There is a unit test for this (hm1) that computes the hmac and compares it to
the known value.  The salted vesion tested offline.

-----

Also, fixed usespace compile issue with not changing KERNEL_SECRET => SECRET.
