      Replace PCRE with PCRE2 where it is available. · b1a3338e
      William A. Rowe Jr authored
      This patch removes the needless assignment of re_erroffset in the conf pool
      by the worker threads; such mistakes break the shared copy-on-write pages of
      memory that should have remained common between all httpd worker processes.
      
      Two de-optimizations are inherent in this patch, the former ovector-on-stack
      opportunity is lost unless implemented as a new general context. Safer that
      we either create a new general context using pool allocation, or recycle a
      per pool or per thread match_data buffer of some arbitrary 10 elts or so.
