* refs/heads/master: (28 commits)
  Use screen's saved view instead of re-querying the server.
  Slightly expand and expose verbose debugging.
  add debugging for x events
  Add a simple debug logging mechanism.
  Simplification; use asprintf where appropriate now.
  Use func attributes where appropriate.
  Fix wins comparison declaration since it's unsigned from XQueryTree().
  Generate name_to_func[] in a clean and readable fashion.
  Shrink tier[] by one after removing matchname in r1.55.
  If the requested group number is invalid, bail but don't kill cwm.
  Quick fix: exit after a failed execvp in u_spawn instead; previously we did in u_exec, but the introduction of re-exec'ing the previous invocation of cwm if 'exec_wm' failed missed the 'exec' failing path. Will likely split out as a proper fix.
  Only exec the fallback when in CWM_EXEC_WM state.
  Typo, from Julien Steinhauser.
  Convert menu-exec-wm from an abritrary exec menu, into a config-based menu from which one may configure (wm <name> <path_and_args>) (and choose) specific window managers to replace the running one. 'wm cwm cwm' is included by default.
  As done for buttonrelease, work specific un-cycling and un-highlighting actions into the keyrelease event, only performing what's actually needed for each; should result in much fewer events against keyreleases. No intended behaviour change.
  Merge group_toggle_membership_leave into the buttonrelease event and only do border work for a group/ungroup action.
  add helper function client_show to bring together like actions for unhide/raise
  Add support for re-exec'ing with SIGHUP; equivalent to the already built-in 'restart' function.
  Use poll and XNextEvent to replace XNextEvent blocking inside the x11 event handler.
  zap stray that snuck in
