V2 testsuite improvements

I've just comitted a buch of changes aimed at making possible testing V2 with 
arbitrary toolset. I can now run

generators_test.py borland

on windows, and it passes! 

The little remaining thing is: declare all toolsets eligible for testing in 
one place. I just got this idea:

1. First, the system looks for a file called test-config.jam, and if found, it 
will set up toolsets.
2. Otherwise, site-config.jam and user-config.jam are loaded and should do the 
same.

Is this sensible?
