Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added ifdefs and unified the code with udpioplugin ... the latter has not been tested (or committed). TODO: still it hangs after ctrl-c BeagleRT (auxiliary tasks do not terminate). TODO: sometimes you can hear dropouts in the transmission. Maybe it is due to pointer drifting. Rebooting BBB fixes/affects this issue.
