Now with experimental MIDI support!

-- changes/fixes

  • Make "alsa" the default backend when both it and "freebob" are present.
  • JACK MIDI patch -- Experimental!
  • allow use of h/w devices that only support big-endian formats, without using ALSA plughw layer.
  • jack_lsp now has a -L flag to show "total latency" values reflecting port connections
  • ALSA driver no longer requires access to a control device (Lee Revell)
  • jack_lsp -t shows port type
  • jackd will exit if -R is used but realtime is unavailable
  • minor change in freebob backend command line options the -d option now takes a 'hw:port[,node]' string as argument instead of a single number. More flexible and consistent with the alsa backend.
  • good old fix about jack_watchdog killing the whole process group instead of the nearest offending client, which is by far a much more reasonable approach IMNSHO. Without this one, and while using QjackCtl under KDE as it seems, jack_watchdog will most likely tear the X server down, not just jackd and some of its clients as originally intended.
  • halve JACK_THREAD_STACK_TOUCH to 500000
  • increase default --port-max option from 128 to 256
  • This patch checks the specified client timeout so that it is enforced that it's smaller than the jack watchdog timeout.
  • Many bug fixes
  • Many documentation updates
