Could search on process id

[GoogleCodeExporter]

This is more of a feature request than an issue but searching by process id
would be nice.

There is no guarantee a window has the _atomPID property set, nor what
machine the process valid on, if its even running, but its still pretty useful.

Below is a snippet taken from
http://stackoverflow.com/questions/151407/how-to-get-an-x11-window-from-a-proces
s-id

      // Get the PID for the current Window.
      Atom           type;
      int            format;
      unsigned long  nItems;
      unsigned long  bytesAfter;
      unsigned char *propPID = 0;
      if(Success == XGetWindowProperty(_display, w, _atomPID, 0, 1, False,
XA_CARDINAL,
                       &type, &format, &nItems, &bytesAfter, &propPID)) {
    if(propPID != 0) {
      printf(" pid: %ld", *((unsigned long *)propPID));
      XFree(propPID);
    }
      }

Sounds good.

libxdo/xdotool already do some window property fetching for things like 
NetWM/EWMH 
support, so adding this should be simple.

I'll try to work on it this weekend.

Fix checked in as svn r2649.

Usage:
xdotool search --pid 12345

You can search by pid and window title, too:
xdotool search --all --pid 12345 "hello world"

This will appear in the next release, but is available now from svn.
