Ever since we switched to the hand-crafted ./configure script, support
for cross-compiling the netsniff-ng toolkit was basically broken.
Restore the abaility to cross-compile our tools by making ./configure
consider the CROSS_COMPILE and SYSROOT variables.
Example for cross-compiling on arm:
$ CROSS_COMPILE=arm-linux-gnueabihf- \
SYSROOT=/usr/arm-linux-gnueabihf \
./configure
$ make
assuming the cross-compiled libraries (and their respective pkg-config
information) are in /usr/arm-linux-gnueabihf.

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.

Since commit 1cc762a ("lookup: Move UDP/TCP port and Ethernet type
lookup into own module") the netsniff-ng tool is the only one using the
dissector infrastructure. Thus we no longer need to conditionally device
HAVE_DISSECTOR_PROTOS, since netsniff-ng is the only tool defining this.
While at it, also remove the __WITH_PROTOS macro which is checked in
dissector_init_ethernet/dissector_cleanup_ethernet but is defined
nowhere. This will cause the functions to be called from both the
ethernet and ieee80211 dissectors, thus make sure we check the
initialization state before freeing as well.

This change implements support for specifying an alternative
installation destination directory by setting DESTDIR when
calling 'make install'.
Example: make DESTDIR=/alternative-rootfs install
It is particularly useful when cross-compiling and installing
in a dedicated directory where for example the rootfs or a
build sandbox for the target architecture is mounted.
By using DESTDIR you can avoid to mess with PREFIX to include
the alternative installation directory!

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 be more consistent with config.h, rename __WITH_PROTOS into
HAVE_DISSECTOR_PROTOS.

To get the normal Makefile a bit cleaner, push the tool specific

Move them out of xutils, so that we can maintain them separately.
Also simplify things a bit.

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.
