  PR5049: fix overbroad effects of naive "*" prefixing; instead use optional "*/" only.
  stap-serverd was incorectly determining that the server could
  stapprobes man page: clarify statement(NUM).absolute and process("path") searching
  PR5049: prefix with "*" any filenames given in "fn@filename:line" probes
  Indentation fix.
  Redirect stderr gets redircted so warnings don't let example script run fail.
  PR6835. io/io_submit.stp: Fix #! start. Convert to normal line-ending.
  PR2895. Add proper #! /usr/bin/env stap line. Make example scripts executable.
  Use INSTALL_PROGRAM, not INSTALL_DATA for executable .stp scripts.
  example index: only warn if old, do not regenerate
  Start/stop the systemtap server from systemtap.exp and not in the top level Makefile.
  Lower statement wildcard test matching threshold.
  Moved details of utrace detach to stap_utrace_detach().
  Saves thread vma information.
  Always generate examples indexes and install examples from srcdir.
  Refer to srcdir spec file Makefile so make rpm works when builddir != srcdir.
  Add index of subsystem and keywords at top of HTML indexes.
  Don't output output, exits, status line in indexes (mentioned in descriptions).
  Disable chmodding of samples/kmalloc-top in spec file since it isn't installed.
  Make sure examples indexes are always generated in builddir.
