Hiltjo Posthuma a7afade170 clear passwords with explicit_bzero
Make sure to explicitly clear memory that is used for password input. memset
is often optimized out by the compiler.

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.
