windows debug popups in build slave mode

[troy d. straszheim]

In certain cases tests can trigger an assertion failure in a lower level library which, when compiled debug, can pop up a dialog box and ruin your whole day.

Evan dug up that:

This code can be used to completely suppress error message popup windows during testing:

   SetErrorMode( SEM_NOGPFAULTERRORBOX );
   _CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE );
   _CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDERR );

Unfortunately, python doesn't seem to include the latter two functions yet.

Seems like this should go into boost.test itself... but some libraries don't use boost.test.

marshal.py now correctly times out subprocesses and kills these, no longer a showstopper.

haven't seen this recently, will leave it around in case it comes up again.

CMake has not been in the Boost repository for a while.
