Redone for clearity
Also removed some redundant stuff.
Use VBO_setstate() so waiters wake up.
Shuffle things a little bit closer to streaming
typo spotted by federico
Move yet a little bit closer to streaming.
Move back into cnt_stream{}
Retire saint-mode.

If there is a need, we'll bring it back as a VMOD.
Introduce the object iterator functions, which will hide the
nasty synchronization bits of streaming.
Isolate req->busyobj in the state engine.
Fix layout of SLT_TTL records from VCL
Add a "private" oh which we can hang pass and error objectcores
from, so that we do not need to special-case locking all over the
place.

Give the busyobj a real reference to the objcore it's fetching.
Turn "request done" into a proper busyobj state.
Tell VBF_Fetch() what we're trying to do, and have it linger until
we have a usable state.
On virutal hosting in Varnis
removed unused file
inline the backend stuff again
Drop no longer used file from Makefile.am
Fix the last oc->oh tests to look at OC_F_PRIVATE instead
Make bans depend on OC_F_PRIVATE
Leave bo->fetch_objcore intact, even as the refcount moves to the object.
