3.6.0rc2

This is the second (hopefully last) Release Candidate of the syslog-ng
OSE 3.6 branch. Some release critical bugs found and fixed.

Bugfixes

• Opening control socket disabled when syslog-ng is used for only
  syntax-checking.
• Reloading a config file containing runtime error now not ends in a crash,
  it is able to fallback to the original config.
  (runtime error: config file is grammatically valid but containing invalid
  value, eg.: wrong database column name)
• Casting error eliminated in Riemann destination when metric is applied to
  an empty field.
• From now, syslog-ng always exclude attributes that conflict with properties
  in Riemann destination (otherwise value of the attribute would override the
  property).
• Patterndb fixed to apply condition even if context-id is missing.
