Both POSIX and glibc use 'restrict' in strcpy(), strncpy().
Let's use it here too.

.../glibc$ grep_glibc_prototype strcpy
string/string.h:125:
extern char *strcpy (char *__restrict __dest, const char *__restrict __src)
__THROW __nonnull ((1, 2));
.../glibc$ grep_glibc_prototype strncpy
string/string.h:128:
extern char *strncpy (char *__restrict __dest,
const char *__restrict __src, size_t __n)
__THROW __nonnull ((1, 2));
.../glibc$
