backend connection bucket allocator and front end connection bucket allocator.
Instead copy the buckets from the backend over to ones that have been created
using the front end bucket allocator. For metabucket this is done by recreating
them, for data buckets this is done by reading them and putting the read data
in a transient bucket.

network filters get flushed to the network. This is needed since
these buckets have been created with the bucket allocator of the
backend connection. This allocator either gets destroyed if
conn->close is set or the worker address is not reusable which
causes the connection to the backend to be closed or it will be used
again by another frontend connection that wants to recycle the
backend connection.
In this case we could run into nasty race conditions (e.g. if the
next user of the backend connection destroys the allocator before we
sent the buckets to the network).
Remark 1: Doing a setaside does not help here as the buckets remain
created by the wrong allocator in this case.
Remark 2: Yes, this creates a possible performance penalty in the case
of pipelined requests as we may send only a small amount of data over
the wire.

member of the proxy_conn_rec struct as we destroy this data more frequently
than other data in the proxy_conn_rec struct like hostname and addr (at least
in the case where we have keepalive connections that timed out and were
closed by the backend).
This fixes a memory leak with short lived and broken connections.

Basicly the persistence is created by keeping the conn_rec structure
created for our backend connection (whether http or https) in the connection
pool. This required to adjust scoreboard.c in a way that its functions can
properly deal with a NULL scoreboard handle by ignoring the call or returning
an error code.

That patch stalled on wrowe's veto. This update introduces a new
"interpolate" keyword to all directives affected, so should meet
his concerns by adding explicit per-directive control (disabled

This fixes that.

from the connection pool twice. This causes this connection to be present
in the connection pool twice. Thus it may be used by different threads
at the same time which causes many troubles (segfaults in this case).
Furthermore implement a logic to prevent double releases to the connection
pool if they are triggered by buggy code and log an error message in this
case.
- mod_proxy_http.c: remove double calls to ap_proxy_http_cleanup
- proxy_util.c: Add logic to prevent double releases of a

into the proxy handler of mod_proxy.
This patch still sets r->connection->aborted to 1 which is currently
vetoed by Roy. Moving it from the scheme handler to the proxy handler
should ease the reimplementation of this, as the scheme handlers only
needs to return PROXY_BACKEND_BROKEN to signal the above situation to
the proxy handler.
mod_proxy.h: Add define for PROXY_BACKEND_BROKEN
mod_proxy.c: Handle PROXY_BACKEND_BROKEN in proxy handler
mod_proxy_http.c: Sent back PROXY_BACKEND_BROKEN if backend broke

just before the final return. This gives modules an opportunity to do
something based on the proxy status.
A couple of examples where this is useful:
-You are using a caching module and would rather return stale content rather
than an error to the client if the origin is down.
-you proxy some subrequests (using SSI - mod_include) and do not want SSI
errors when the backend is down. If you would normally return
HTTP_BAD_GATEWAY, you may have a module that serves some other content.
