* Tue May 13 2014 Paul Wouters <pwouters@redhat.com> - 1.3.6-1

Browse Source 
- Updated to 1.3.6 - using github-only monstrosity packaging
- Resolves: rhbz#1051785 (new upstream version available)
- Resolves: rhbz#868391 xl2tpd sends response packets from wrong IP address
- Revert: rhbz#929447 Incorrect "ipparam" manipulation
- Resolves: rhbz#1055196 Don't order service after syslog.target
- Resolves: rhbz#984332 xl2tpd tmpfiles configuration file in wrong directory
- Removed patches merged in upstream.
- FIPS patch updated with advertising clause for openssl in xl2tpd -V
  (although the GPL code was already basically taken from openssl)
