Fixing this means that regexes using \\ will break suddenly because they
need to become \\\\ ... I dunno what to do about that.

HIDE=yes" in the Configuration file.  Basically this patch adds a
pre-generated include/hide.h file and the helpers/UpdateHide script for
updating it when new functions are added. All other changes were just to make
sure the conf.h file is really included (which itself includes hide.h if HIDE
is defined), because we need the redefinition list everywhere to hide every
function.

- eliminate a few warnings
- get rid of the static local in parse_uri_components_regex by
  creating util_uri_init() routine called from main()
- don't use static re.match 'cause it's not thread safe
- factor some common code from the win32 and unix case into common_init()
- update dependencies

still hacking.

It contains a routine parse_uri_components_regex() and friends which
tries to break an URI into its parts. These parts are stored in a new
uri_components structure within each request_rec and are therefore
available to all routines which act on a request.
Additionally, an unparse routine is supplied which re-assembles the
URI components back to an URI, optionally hiding the username:password@
part from ftp proxy requests, and other useful routines.
Within the structure, you find on a ready-for-use basis:
   scheme;     /* scheme ("http"/"ftp"/...) */
   hostinfo;   /* combined [user[:password]@]host[:port] */
   user;       /* user name, as in http://user:passwd@host:port/ */
   password;   /* password, as in http://user:passwd@host:port/ */
   hostname;   /* hostname from URI (or from Host: header) */
   port_str;   /* port string (integer representation is in "port") */
   path;       /* the request path (or "/" if only scheme://host was given) */
   query;      /* Everything after a '?' in the path, if present */
   fragment;   /* Trailing "#fragment" string, if present */
plus flags to indicate whether the strings have valid values.
This is meant to serve as the platform for *BIG* savings in
code complexity for the proxy module (and maybe the vhost logic).
NOTE: This code is enabled only if the WITH_UTIL_URI define is set;
currently this is not enabled by default.  [Martin Kraemer]

We have three locations where one can construct a string in rewriting rules by
expanding $N, %N, %{NAME} and ${map:key}:

  - RewriteCond <Location-1>  ...
  - RewriteRule ...           <Location-2> ...
  - RewriteRule ...           ...          [..,E=NAME:<Location-3>,...]

And just after I've added exact comments of what we expand in each location, I
discovered that they are expanded totally inconsequent. For <Location-3> the
%{NAME} and ${map:key} constructs were not expanded (ok, perhaps not really a
%major drawback) and for <Location-1> the ${map:key} construct was not
%expanded while for <Location-2> all are expanded. At least the missing
${map:key} expansion for <Location-1> is horrible because this way we
unnesessarily restricted the usefulness of RewriteCond dramatically.

Perhaps I should add more source comments to mod_rewrite.c
to discover that it then can even can cook a cake now.... ;-)

variable (one of the mod_rewrite FAQs) even in per-server context.  One just
has to use %{LA-U:REMOTE_USER} instead of %{REMOTE_USER} there.  Notice that
%{REMOTE_USER} is also useful, but only for per-dir context.
