[PATCH 19/24] strtod.3: SYNOPSIS: Use 'restrict' in prototypes

Both POSIX and glibc use 'restrict' in strtod(), strtof(), strtold().
Let's use it here too.

.../glibc$ grep_glibc_prototype strtod
stdlib/stdlib.h:117:
extern double strtod (const char *__restrict __nptr,
char **__restrict __endptr)
__THROW __nonnull ((1));
.../glibc$ grep_glibc_prototype strtof
stdlib/stdlib.h:123:
extern float strtof (const char *__restrict __nptr,
char **__restrict __endptr) __THROW __nonnull ((1));
.../glibc$ grep_glibc_prototype strtold
stdlib/stdlib.h:126:
extern long double strtold (const char *__restrict __nptr,
char **__restrict __endptr)
__THROW __nonnull ((1));
.../glibc$
