Introduce new example kernel module: panic_string

The panic_string module accepts input from a device file over the write(2)
system call.

It prints panic(9) message passed from user space, e.g.:

echo "Hello world" > /dev/panic

If a string is empty or contain only whitespaces it's ignored and panic(9)
is not triggered. If a non printable character is passed within the input
buffer, the rest of the string is ignored.

This module performs the sync(8) operation before panic(9) to flush cache.
