... and this patch fixes some 'no previous prototype' warnings:

common/password.c:114:5: warning: no previous prototype for ‘is_passwd_default_enable’ [-Wmissing-prototypes]
 int is_passwd_default_enable(void)
     ^
common/password.c:120:5: warning: no previous prototype for ‘is_passwd_env_enable’ [-Wmissing-prototypes]
 int is_passwd_env_enable(void)
     ^
common/password.c:230:5: warning: no previous prototype for ‘write_env_passwd’ [-Wmissing-prototypes]
 int write_env_passwd(unsigned char *sum, size_t length)
     ^
