netsniff-ng does not delete created rfmon device in case of
panic (for example - bad pcap filter expression), so added ability to
add callback func when panic will be happen and delete rfmon device.

The ioops module is only needed in geoip.o, thus make it dependent on
CONFIG_GEOIP.

Building astraceroute fails on EL systems because
TPACKET_V3 is not available. Astraceroute functions
properly without ring_rx.o.

Both tools are already prepared to handle NULL return values of the
geoip_* lookup functions, so we might as well build them without geoip
support if not needed/present.

Improve the build system, so that configuration files are installed
per tool basis. Also, introduce post_install targets, so that config
files can be altered in some way, e.g. done by trafgen. Moreover,
move custom targets from Extra to tool-specific Makefiles.

To get the normal Makefile a bit cleaner, push the tool specific
build options into <tool>/Makefile.

We do not want to maintain duplicate code, so move this into a separate
file and name those *_generic() helpers.

We decided to get rid of the old Git history and start a new one for
several reasons:
*) Allow / enforce only high-quality commits (which was not the case
for many commits in the history), have a policy that is more close
to the one from the Linux kernel. With high quality commits, we
mean code that is logically split into commits and commit messages
that are signed-off and have a proper subject and message body.
We do not allow automatic Github merges anymore, since they are
total bullshit. However, we will either cherry-pick your patches
or pull them manually.
*) The old archive was about ~27MB for no particular good reason.
This basically derived from the bad decision that also some PDF
files where stored there. From this moment onwards, no binary
objects are allowed to be stored in this repository anymore.
The old archive is not wiped away from the Internet. You will still
be able to find it, e.g. on git.cryptoism.org etc.
