>Description:

For reasons that do not matter here I am trying to write a function that tells
the caller, if the process is being debugged.

This turns out to be harder as I initially thought: the PSL_TRACED flag has
been moved from struct proc:p_flag to :p_slflag. Only the former is copied
over to struct kinfo_proc2.

We need to fix that (by adding a p_slflag field in kinfo2?), then update the
code in ps(1) and fix its manual page (which still documents P_TRACED to be
available in the process flags).

>How-To-Repeat:
Read the source

>Fix:
Provide p_slflag in struct kinfo_proc2.
