[Jack-Devel] JACK1 0.125.0rc1 now available

There's a new release candidate of JACK1 now available. Because of the magnitude of a couple of the changes, some wider testing would be appreciated before 0.125.0 can be released. http://jackaudio.org/downloads/jack-audio-connection-kit-0.125.0rc1.tar.gz (tagged in git as 0.125.0.rc1) Changes since 0.124.1, in rough order of significance: * use topological sort when ordering clients. Previous sorting implementation would generate incorrect ordering of clients in some (unusual, but not uncommon) conditions. * in the alsa_midi slave driver, fix hotpug device enumeration. JACK1 will now respond to MIDI devices being connected and disconnected while running. * increase maximum size of a single JACK MIDI event to 64 bytes * in the alsa_midi slave driver, fix thread start/stop handling when freewheeling * add support for jack_port_rename() * drop support for CPU cycle counting clock, use kernel clocksource instead * fix a double-fork that left zombie processes around * improve the validity and usability of the return value of jack_frame_time() * fix failing metadata look up by clearing UUID parsing buffer before use * support unescaped double quotes in $HOME/.jackdrc * fix memory leaks of metata key/value pairs * fix crash caused by incorrect jack_error() format string * remove option help from jackd and point user at documentation * fix problems with garbage keys in metadata * fix out-of-tree builds * update configure.ac to work with current-ish autotools with less errors * use gcc atomics and CLOCK_REALTIME for generic CPU builds * a handful of other minor bug fixes Contributors: Hans-Peter Portner, Fons Adriaensen, Erik de Castro Lopo, Filipe Coehlo, David Robillard, Adrian Knoth, Dominic Sacré, Peter Nelson, Rui Nuno Capela, Robin Gareus, Peter Nelson, Paul Davis
