(error): Use exit instead of ExitProcess so that stdio buffers get flushed.

* utils.sgml: Update section for strace.
(attach_process): Use window pid if cygwin pid isn't available (yet).
(create_child): Use either DEBUG_ONLY_THIS_PROCESS or DEBUG_PROCESS,
exclusively. (Suggested by Conrad.Scott@dsl.pipex.com)
(proc_child): Do it here, instead, after first debug event. This should work
around inexplicable races with DebugActiveProcess.
(dostrace): Pass any pid argument to proc_child.
* strace.cc: Use specific cygwin includes, as required.
(load_cygwin): New function. Loads cygwin DLL, if necessary.
(attach_process): Attaches strace to a running process.
(dostrace): Accept pid argument. Attach to pid if supplied.
(usage): Describe -p option. Correct system description.
(longopts): Alphabetize.
(opts): Ditto.
(main): Ditto. Handle -p option.

when overriden by command line.

window. New option '-S x'. Flush buffered output every x seconds.

more obvious.
