Project Filelist for OpenVAS

This is the first release of the openvas-scanner 5.1 module for the Open
Vulnerability Assessment System 9 (OpenVAS-9). Compared to the previous
major release the scanner now serves via a unix file socket instead
of a tcp socket which simplifies the setup, handling and code-base.
Also, the feed synchronisations were consolidated into a single method.
And in general the scanner becomes lighter, faster and more robust.

Many thanks to everyone who has contributed to this release:
Benoît Allard, Hani Benhabiles, Henri Doreau, Sven Haardiek, Matthew Mundell,
Timo Pollmeier, Jan-Oliver Wagner and Michael Wiegand.

* Moved the TLS certificate management script to module openvas-manager.
* Merged the two feed sync scripts into a single one that can handle
  both, the Community Feed and the Greenbone Security Feed.
* New command line options --unix-socket, --listen-mode,
  --listen-group, --listen-owner and --gnupg-home.
* Removed command line options --listen, --port, --gnutls-priorities and
  --dh-params.
* The nvt summary isn't send anymore as it is not used anymore.
* Send a "Host dead" host detail when the host is dead.
* Dropped scanner preferences cert_file, key_file and ca_file.
* Add scanner preferences timeout_retry and scanner_plugins_timeout.
* Reduced memory consumption and improved performance
