when reading from a remote HTTP server in proxy.

Modify receive/send loop in proxy_http and proxy_ftp so that
should it be necessary, the remote server socket is closed before
transmitting the last buffer (set by ProxyIOBufferSize) to the
client. This prevents the backend server from being forced to hang
around while the last few bytes are transmitted to a slow client.
Fix the case where no error checking was performed on the final
brigade in the loop.

Garbage characters sometimes appeared after a legitimate folded header.
We weren't allocating an extra byte for the trailing null, or copying it,
when called from get_mime_headers (folding is in use, and ap_rgetline is
responsible for allocating memory).  No need to worry about a trailing
LF - it's already been nuked.

I checked the partial line code to see if it had a similar bug.  It looked
like it did, and that the code which trims the back end of the line would
run multiple times and whack innocent bytes.  However, gdb showed that this
section of code appears to be dead due to input filter chain changes.

also, removed an assignment to a dead variable.

Now it will be relative to the $prefix if $sysconfdir shares a common prefix,
or it will remain relative to $sysconfdir.

to the target host; use that common function for proxy HTTP and proxy
CONNECT

In that new function, fix this problem:

     Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
     when we can't get a socket in the specified address family.  We may
     have gotten back an IPv6 address first and yet our system is not
     configured to allow IPv6 sockets.

An example host is www.ipv6.org.  The first address I get back is
an IPv6 address, but my machine may not be configured to allow an
AF_INET6 socket.

Before the fix: The apr_socket() failure was fatal.
After the fix:  When apr_socket() fails, we go to the next address from
                the resolver, successfully create a socket in the
                specified family (AF_INET), and all is well.

(an unrelated fix in this commit was to pass a server_rec in a broken
ap_log_error() call)
