Re: [libvirt] [PATCH 7/6] qemu: allow filtering events by regex

When listening for a subset of monitor events, it can be tedious to register for each event name in series; nicer is to register for multiple events in one go. Implement a flag to use regex interpretation of the event filter. While at it, prove how much I hate the shift key, by adding a way to filter for 'shutdown' instead of 'SHUTDOWN'. :) * include/libvirt/libvirt-qemu.h (virConnectDomainQemuMonitorEventRegisterFlags): New enum. * src/libvirt-qemu.c (virConnectDomainQemuMonitorEventRegister): Document flags. * tools/virsh-domain.c (cmdQemuMonitorEvent): Expose them. * tools/virsh.pod (qemu-monitor-event): Document this. * src/conf/domain_event.h (virDomainQemuMonitorEventStateRegisterID): Adjust signature. * src/conf/domain_event.c (virDomainQemuMonitorEventStateRegisterID): Add flags. (virDomainQemuMonitorEventFilter): Handle regex, and optimize client side. (virDomainQemuMonitorEventCleanup): Clean up regex. * src/qemu/qemu_driver.c (qemuConnectDomainQemuMonitorEventRegister): Adjust caller. * src/remote/remote_driver.c (remoteConnectDomainQemuMonitorEventRegister): New flags can always be safely handled server side.
