(busyobj).

This replaces the current "VID" as visible in the X-Varnish header.

The new "stolen numbers" causes a lot of testcases to need updates,
most trivial, but a few needed more extensive work to be predictable
under the new circumstances.

Next step is to carry this change through in VSL, and link all
the VXID's to each other.

Old indentation made the :ref: into a literal block, thus not a real
reference. This should do the trick.

original ESI processed request, rather than to the included
requests.

Fix by allocating/cloning a new request for the esi:include
transactions.

Eliminate the t_rx timestamp, I doubt it made anything clearer
for anybody.

Add timestamp to SessOpen VSL record.

backend at all.  The retry is only (pseudo-)valid when we have not received
anything at all, indicating that the backend closed before it got our request.

Also don't retry if we sent the request body (not part of test-case).

Fixes #1156

from RFC5737's TEST-NET-1 and put a comment there to explain.

I fear this is a loosing battle, but at least this is more "official"
than the previous "10.255.255.255" choice.

Fixes #1159

It was a nice idea, but obviously compiler-writers and/or language
laywers are pussies who hate table-based programming :-)

which subprocess we are locking down.

Inspired by Geoff's patch for Solaris, but does not solve the
Solaris problem, only makes it easier to fix.

Fixes a compile error (incorrect signature for SES_Delete() in
cache_waiter_ports.c)

If the ban lurker finds a busy object, skip the object and defer the
checking to a later pass.

No test case because it is very timing sensitive (but see the trac bug
report for a VTC-file that mostly triggers it on the 3.0 branch only)

Fixes: #1162

There is a short window of opportunity between HSH_Insert() and
HSH_Unbusy(), where the locks are released and the expiry thread can
try to expire an object that is still busy (for objects with very
short TTL). This patch makes the expiry thread check for busy objects
and wait if the head of the binheap is busy.

No test case as the window is too small.

Fixes: #1150

An attempt to nuke a busy object will end in assertion.

eliminate two SES_Charge() calls that have nothing to charge.

when we come back from the waiter, to lessen amount of work
waiter does.
