The mod_rewrite ``Break Its Heart'' patch:

  - the rewriting engine now is really very well documented, so
    all Apache developers should be able to understand it now ;_) Try it
    out: look at the new apply_rewrite_list and apply_rewrite_rule functions
    and try to understand it...

  - the rewriting engine no longer contains any redundant stuff for the
    proxy-throughput, redirection and per-dir cases. This makes it even more
    clear to understand and avoid future bugs like the following:

  - fixed the query string bug recently discovered by Mark:
    | RewriteRule ^foo            /bar?query  [R]
    | RewriteRule ^foo http://host/bar?query  [R]
    where the second rule's query string was escaped.
    (fixed by avoiding this as an extra case ;_)

  - fixed the nasty redirection bug recently discovered in c.i.w.s.u
    | RewriteRule ^(.*[^/])(.*) ${vhost:$1|$1}$2 [R,L]
    where the expansion of ${vhost} to http://... was too
    late for the rewriting engine to accept it as a redirect.
    (fixed by new and more accurate evaluation order)

  - split out the fully-qualification of URLs into own named function
    fully_qualify_uri(r). This avoid redundancy, too.  Also incorporate
    updated APACHE_SSL #ifdef'edchanges to mod_rewrite.c from Ben's latest
    1.2.4+ssl_1.11 patch

  - make cmd_rewriterule static (this was left over from old days of the
    mod_rewrite_compat which never found its way into the core distribution)
