Fix three problems with pcre for portability;

  1. study.c's pointer arg didn't jive with pcre_fullinfo()'s prototype,
     however there was no (trivial) way to get them to concur.  Cast in
     this case was the least of several evils.

  2. byteflip had an error for high-bit set bytes, because right shift
     signed is allowed to extend the sign bit.  These had to be unsigned,
     and the real_pcre types were the safest way to do this.

  3. split byteflip into byteflip2/4, to drop size truncation emits, 
     as the arguments are unambigiously 16 or 32 bits as defined 
     in pcre_internal.h.

generation in the scoreboard so that mod_status can accurately
represent workers in processes which are gracefully terminating.

New child processes with worker MPM can take over slots of
individual threads within gracefully terminating processes.
Sometimes this is a problem (too many of these gracefully
terminating processes), so it is helpful to have mod_status
provide the information required to recognize these processes.
