Normalize the way apache modules are built on windows, now that all of subversion is using the dynamically linked apr library. This change effects only the outputted mod_dav_svn and mod_auth_svn projects. * build.conf (mod_dav_svn, mod_authz_svn) add dependencies for windows * build/generator/gen_win.py (WinGeneratorBase.get_win_depends_impl): change to make use of nonlibs option (WinGeneratorBase.adjust_win_depends, WinGeneratorBase.get_win_lib_dirs, WinGeneratorBase.get_win_libs, WinGeneratorBase.get_win_sources): delete some special case apache code that's no longer neccessary
