During SEGV handling under pcp-htop several incorrect strings were
observed - in particular reporting htop as the binary name instead
of pcp-htop. This is something we want to be crystal clear on when
we request user stack traces etc, so make sure this cannot be done
incorrectly.
One review request relating to the PCP platform is to have
a clearly separate binary from the regular htop so that we
have no confusion as to what is being requested to run, to
aid debugging, and a bunch of other good reasons.
This commit renames htop.c to CommandLine.c and provides a
minimal htop main function for 'native' platforms to use.
The PCP version of this will setup libpcp.so and then call
the same CommandLine_run function as regular htop.
