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.

which would prevent the relocation of an httpd binary without having to
specify the -f flag.

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

Add note about the fact that we aren't doing config substitution properly.
This is a showstopper, IMHO.

the request over the unix socket

it isn't perfect (EINTR, partial reads) but it is good enough to
avoid segfaulting if some code tries to verify that cgid is active

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)

normal case worked OK, but due to the recursion and multiple exit points,
input bytes could go thru charset translation multiple times or not at all.

The latter is the dominant style in apache.  The only
other places they can be found (AFAIK) are mod_ssl and
mod_rewrite.

Also, since each line under a make rule is treated as a new subshell,
it's not necessary to surround the whole line in ()s.
