tty info (^T): Add optional kernel stack(9) traces

It is often useful for developers and administrators to determine a running
thread's stack for debugging purposes.  With this feature, using ^T will
print that information

For now, the feature is disabled by default.  Enable with sysctl
kern.tty_info_kstacks=1.
