When we do a lookup, we first try without the lock, if this gives
us a refcnt==0 objhead, we try again, with the lock.

When we deref an objhead, we would decrement the refcnt, holding oh->mtx,
then lock the critbit-lock and remove it from the tree.

It might be possible for a locked lookup to find an oh we just decremented
the refcnt off, and we did not check for refcnt==0 in that case.

Fix this, by removing the oh from the tree, holding the critbit-lock,
before decrementing the refcnt.  This way, a locked lookup can never
find a refcnt==0 oh in the tree, and the unlocked lookup still catches
this with the refcnt==0 check.

First secret superpower is "-x dumpmdoc" which emits a -mdoc suitable
table of all run-time parameters, which can be absorbed into the
varnishd.1 manual page, so we do not have to maintain the text in
two different places.

If the master pid is active when we start, we issue a message about
this, (with a hint about -n) and exit.

If the master pid is not active, but the child pid is, we issue a
message about it presumably being busy dying, dump the SHMFILE and
create a new one.  (This only saves our bacon, if the dying
process manages to close the listening sockets before we need them).

This should end any confusion that might arise from accidentally
running multiple varnishes at the same time.
