Make sure to explicitly clear memory that is used for password input. memset is often optimized out by the compiler. Brought to attention by the OpenBSD community, see: https://marc.info/?t=146989502600003&r=1&w=2 Thread subject: x11/slock: clear passwords with explicit_bzero Changes: - explicit_bzero.c import from libressl-portable. - Makefile: add COMPATSRC for compatibility src. - config.mk: add separate *BSD section in config.mk to simply uncomment it on these platforms.
