mausezahn dependencies and build options were not yet documented.
Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

After some back and forth, we decided that it is easier to maintain
mausezahn in a staging directory until it is fully reworked and
cleaned up to be ready to be fully integrated. This way, it is better
than having it in a separate branch, and we can also accept patches
from outside more easily. Also, while at it, fix up some function
mismatches with libcli.

Hideo Hattori wrote a set of auto completion scripts for zsh that
support netsniff-ng tools. Big thanks for that! Follow-up commits
still need to address updated command-line options.

Break out the timestamping part of the ring.h file, since it's not
directly related to the {t,r}x_ring. Also inlining doesn't make
sense here.

When do not detect any shellcode, make sure we return the original

The return values is always 0 and it is never checked anyhow, so make
the function void.

We need to break if we get NULL from pkt_pull() but the actual check was
inverted. This was discovered by the coverity scanner.

This way the coverity scanner will no longer complain about dereference
before NULL checks right before xfree().

In certain error cases, the file/socket descriptors are not closed
in geoip_get_database(). This was discovered by the coverity scanner.

Check return value of pkt_pull before dereferencing it (even though we
check the packet length before and pkt_pull _should_ never return NULL).
This was discovered by the coverity scanner.

The coverity scanner found the macro used as argument to sizeof
suspicious. Use sizeof the destination buffer instead.

Allow to define custom compile flags, e.g. ...
make CFLAGS="-O2 -Wall"
... and also allow to overwrite ccache variable:
make CCACHE= all
Also do some minor fixes when built with -O2 -Wall.

We can just replace int with uin32_t, that's no problem. Also
fix one case where we moved to uint16_t.

Add a more detailled description of netsniff-ng's -D option into
the man-page.

With commit [1] in the kernel, we can also store the timestamp
source in the pcap packet header for later analysis. We do this
by splitting the netsniff-ng's u32 ifindex into u16 tsource and
u16 ifindex. Older kernel do not support the timestamp source in
PF_PACKET, so it will stay 0 and is compatible with older
netsniff-ng binaries.

Now, with PF_PACKET's extension, we can see what kind of sw/hw
timestamp is being reported to us [1]. Thus, report it in the
dissector.

Set TX timestamping to HWTSTAMP_TX_OFF. We do not use it, therefore
do not waist time keeping track of it.

For TX this call is completly useless and has no effect whatsoever.
Therefore, remove it. For the RX part, this call makes perfect
sense, not for the other one currently.

Maybe in short term future, before the next release, we will think
about putting the README file for users into DOCDIRE, since the
rest is not really interesting for users, but probably only for
developers.

We should only put the things here that are interesting for users,
thus, add steps to verify a release from the Workflow document.

Lets move CodingStyle, SubmittingPatches, and Sponsors into the
root directory of netsniff-ng and remove the Documentation folder.
Some of those files are quite bloated, and most of these things
should be in the man-pages anyway. They should be the only big
sources of documentation, nothing else.
The rest is currently put here: http://pub.netsniff-ng.org/docs/
