patches 1 though 5 merged, thanks!

I did fixes for make dist and VPATH builds on top. Please make sure to
test those next time. The ctf-traces/ directory location should be
received by tests through env. var., so Makefile.am can target the
$(srcdir) for those test traces.

We also have one test that fails, we should look into that.

Thanks!

Mathieu
