[Rivet] Removing yaml-cpp bundling from Rivet 2.0

[Andy Buckley]

Hi all,

A quick poll: does anyone object to removing yaml-cpp from the Rivet
tarball for version 2.0?

This doesn't mean not using it, just that we don't try to be clever and
conditionally install it anymore: that's caused as many problems as it's
solved, I think. We would add yaml-cpp discovery/installation to the
bootstrap script of course. [Actually, there are sufficiently many
differences between Rivet1 and Rivet2 dependencies that I think we'll
probably need to make a separate rivet2-bootstrap...]

If no-one objects, I will remove this before the beta release (I'm doing
lxplus installation testing at the moment so don't mind fiddling with
build details.)

Andy
