Removed CONFIG_LIBC_ARCH_BZERO. bzero() is a deprecated interface. There are no architecture-specific replacements and, if there were, they should replace memset(), not bzero().

C library: Add ffs(). Add strings.h. Move strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are legacy functions; the contemporary counterparts should be used instead.
