tracing/kprobes: Support "string" type
Support string type tracing and printing in kprobe-tracer.
This allows user to trace string data in kernel including __user data. Note
that sometimes __user data may not be accessed if it is paged-out (sorry, but
kprobes operation should be done in atomic, we can not wait for page-in).
Commiter note: Fixed up conflicts with b7e2ece.
