[core] some header cleanup provide standard types in first.h instead of base.h provide lighttpd types in base_decls.h instead of settings.h reduce headers exposed by headers for core data structures do not expose <pcre.h> or <stdlib.h> in headers move stat_cache_entry to stat_cache.h reduce use of "server.h" and "base.h" in headers
