[Tobias Berner]

SVN commit 12160 by tcberner:

This is an initial implementation to test a feature added recently in the linux
builds of kscreenlocker.

It blocks debuggers from tracing its process, using the linux call prctl(PR_SET_DUMPABLE, mode).

FreeBSD introduced a similar feature in 277322 procctl's PROC_TRACE_CTL:

    # gdb --pid <pid of kscreenlocker>
