Add --enable-sigusr2 to use SIGUSR2 rather than SIGWINCH for graceful
stop, which requires APR 1.7+.

* configure.in: Add --enable-sigusr2; define AP_SIG_GRACEFUL_STOP* in ap_config.h.

* include/ap_mpm.h: Define AP_SIG_GRACEFUL_STOP* conditionally.

* server/mpm/prefork/prefork.c (child_main): Don't mention SIGWINCH.
