Fixes for the process_results() method.

The result_string variable was accidentally deleted in the attempt to fix the STDOUT and STDERR
problems.

Bug fix, the disassemble_result() method is now out of the specific API.

Updated of the copyright statement and removal of dead imports.

Second attempt at r10124. The last commit contained no code changes!

Fix for the run_command_queue() method.

This was broken by the 2to3 command!

Bug fix for the STDOUT and STDERR handling by the multi module.

The IO streams are no longer lost in the case of an error. This allows the relax test suite to
function correctly in uni-processor mode. The multi-processor mode might require more work.

Removed all STDOUT and STDERR handling in the multi-processor model-free specific code.

This is 100% handled by the multi module.

Modified the IO redirection methods in the Processor base class.

The original IO streams are stored and then restored instead of sys.__stdout__ and sys.__stderr__.

Reverted r10119 as this was not fixing the IO redirection problem.

The command used was:
svn merge -r10119:10118 .

Bug fix for IO redirection!

This may cause problems, but now IO redirection has been fixed.
