+- Update to version 0.6.6:

+  * Additional improvements and cleanups
+  * Overall speed-up typically 5.2%
+- Change soname to 0_6, and at the same time set min version for

+- Modernize _service and spec to more current way of doing rust

+- Use ldconfig_scriptlets macro for post(un) handling.
+- Fix license tag to BSD-2-Clause AND ISC
