Avoid more compiler warnings.
* libc/stdlib/btowc.c: Add missing header.
* libc/stdlib/getopt.c (getopt_internal): Initialize variable.
* libc/stdlib/system.c (do_system) [__CYGWIN__]: Add declaration.
* libc/stdlib/wctob.c: Add missing header.
* libc/string/strcpy.c (strcpy): Avoid warnings.
* libc/string/strrchr.c (strrchr): Likewise.
