[libvirt] [libvirt-snmp][PATCH v5 0/4] Add SNMP trap/notification support

The fifth version. In case we build against libvirt older than 0.9.0 (which have old event API), we need to include some sources from libvirt git. So we are able to run even on older RHELs, like 5.6. Those files were copied to our git and modified very slighty. Finally, we have a proof-of-concept implementation of SNMP trap. Two new files were first generated using mib2c then edited, so be careful when re-generating them. Destination of traps is defined in snmpd.conf (trap2sink), and to receive them snmptrapd must be configured and up. The idea behind is - create a thread in which we poll for domain events. Once we receive event notification, we just fire up trap sending. Michal Privoznik (4): Add notification-type object to libvirt MIB Add libvirt error handling function Create functions to fill in and send notification packets. Add SNMP trap/notification support.
