[Buildroot] [PATCH v3,1/2] package/daq3: new package

[Fabrice Fontaine <fontaine.fabrice@gmail.com>]

Add daq3 package to be able to add the snort3 package.

snort3 has an official dependency on daq 2.2.2 but this version is two
years old so it seems more reasonable to add a daq3 package instead of
a daq22 package.

daq3 (and daq 2.2.x) is not compatatible with snort as daq_load_modules
has been removed from daq 2.2.x

daq3 package has been created from the daq package, here is a summary of
the changes:
- Drop patch (not needed anymore)
- Enable parallel build as there is no more tokdefs.h
- Drop libdnet dependency
- Drop host-bison and host-flex dependencies
- Drop libpcap workarounds
- ipq module dropped since version 3.0.0-alpha1 and
  https://github.com/snort3/libdaq/commit/80c62799a936118c80894bf91f396c8aa8ba45a6
- Add LICENSE file (same content than COPYING)
- Update hash of COPYING (project name and GPLv2 text updated with
  https://github.com/snort3/libdaq/commit/46e8722da230082a5728175270ea3c04432d1af0)
- Add a dependency on gcc 4.9 for {t,u}h_{d,s}port that are protected on
  glibc by _FAVOR_BSD (and so !defined _GNU_SOURCE) until version 2.19:

Changes v2 -> v3 (after review of Heiko Thiery):
 - Bump to latest upstream version (and so drop second patch)
 - Update indentation of hash file to two spaces)
 - Fix first patch
