Better support Win32/VS2005 out-of-the-box with trunk.
* flood_farm.c
(run_farm): Accept APR_INCOMPLETE from apr_thread_join for Win32.
* flood/flood_pcre.c, flood/flood_pcre.h: Import PCRE wrappers from httpd.
* flood/flood_round_robin.c: Bring in PCRE wrappers if needed.
* flood/NOTICE: Update; note PCRE wrappers inclusion.
* flood/flood.vcproj: Add VS2005 project file.
