Two things, on trivial-ish and the other serious-ish.

The trivial thing is that I think we should put the actual
rollback in VRT_Rollback() (give it an VCL_HTTP argument) so that
std.rollback just wraps that.

The other thing is that I'm not even close to being convinced that
resetting the workspace is safe anymore, and I have no idea how I
can convince myself that it is, in a world full of VMODs.

We may have to give up on that, and only rollback the struct http.
