[PATCH 3/3] Do not reset bereq on retry. Add rollback_bereq for this, purpose.

[Poul-Henning Kamp]

We chatted about this on IRC today, and this is just to keep everybody
in the loop:

In general, I'm trying to slim down VCC to be "just the language" and
'rollback' is one of the remaining bits I'd like to get out of there,
so the new improved rollback goes into vmod.std.

We leave the "rollback" which VCC implements alone for 4.x

I have added a new VMOD data type "HTTP", which returns an entire
HTTP request/response (struct http *), so that somebody can now
implement the rollback functionality in vmod.std, so the end result
will become:

	std.collect(req)

	std.collect(bereq)
