Updated the internal Boost Build testing system to use the Python subprocess module (introduced in Python 2.4) for running external processes instead of popen2 (deprecated since Python 2.6). We are already using Python 2.4 features in this codebase so there is no need to support Python releases older than 2.4.

Related changes:
  * BoostBuild.Tester & TestCmd.TestCmd interfaces now accept external process parameters as a list of strings, thus avoiding problems with parsing arguments containing spaces.
  * Avoided a potential process hang in case an external process being run prints out enough output to fill up the OS's pipe buffer (OS would pause the process until someone read the data from the pipe but the testing framework would not do this until the process in question had terminated).
