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

Removed printsf, an unused secure testing printf variant. This variant does not apply now that each test has its own secret.
...
Fixed unused variable in libtest161 in kernel compiles.

Changed userspace secprintf to use "say" function, which should be atomic wrt
...
console writing if write works properly.

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.

Previous change that changed SECRET to a string broke userland compiles

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.

1) Moved tprintf and related functions to their own file in common/libc/printf/tprintf.c.
...
This file is included by both libc and hostcompat.
2) Changed printf -> tprintf in all testbin programs
