Subject: support multiline data output from scripts run under the grapher

This is accompanied by support for multiline output in hover text.

* grapher/StapParser.cxx (ioCallback): Read data 'til the end of line
  character, not just '\n'. Be careful to use I/O functions that don't
  treat '\n' specially.
* grapher/StapParser.hxx: ditto
* grapher/CairoWidget.cxx (CairoTextBox::draw): Perform line breaks
  for hover text.
* testsuite/systemtap.examples/general/grapher.stp: Do multiline
  output of keyboard events. Also, fix longstanding breaking in the
  pty probe.
