Add an --enable-reduced-exports configure option to link libmain.ausing ld's --whole-archive mode and avoid building exports.c entirely.This reduces the size of a minimal httpd binary by 18% on Linux/x86_64(687K to 560K) with no difference to the set of symbols available tomodules.This option is only appropriate to use if using a shared libapr*build, hence is non-default.* configure.in: Add --enable-reduced-exports; disable httpdunit build if used. Define AP_FORCE_EXPORTS if not enabled (default) in place of AP_USING_AUTOCONF.* server/main.c (ap_suck_in_APR): Only build if AP_FORCE_EXPORTS is defined.* Makefile.in: Link libmain.la using LIBMAIN_LIB.* server/Makefile.in: Conditionally build exports.c into libmain.
