Update strace-graph to handle current strace output

[Keith Owens]

strace-graph does not work with the current strace output.  These patches
bring it up to date and fix a few bugs.  You can also get this from git://
git.code.sf.net/u/kaos/strace under branch graph.

Keith Owens (5):
  strace-graph: Set use strict and use warnings
  strace-graph: Handle strace -T
  strace-graph: Handle recent strace output
  strace-graph: Cope with clone immediately followed by exit
  strace-graph: Print the pid in the graph
