  * core: Limit ap_pregsub() to 64MB, add ap_pregsub_ex() for longer strings.

    The default limit can be adjusted at compile time using AP_PREGSUB_MAXLEN.

    mod_setenvif: Log error on substitution overflow.



    IMPORTANT: This could break existing configurations which rely on 

               substitutions > 64MB.  Those sites need to rebuild with an

               override of AP_PREGSUB_MAXLEN.

               2.4.x has a much smaller limit on ap_pregsub() because that change

               was introduced with the new release.



    trunk patch:

       util.c: too many to list, as it is tied up in other added features and follow-

               up fixes; I started with 2.4.x HEAD and backed out some semantic changes

               in the code of interest
