[PATCH 16/22] mempcpy.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar]

glibc uses 'restrict' in mempcpy(), wmempcpy().
Let's use it here too.

.../glibc$ grep_glibc_prototype mempcpy
string/string.h:384:
extern void *mempcpy (void *__restrict __dest,
		      const void *__restrict __src, size_t __n)
     __THROW __nonnull ((1, 2));
.../glibc$ grep_glibc_prototype wmempcpy
wcsmbs/wchar.h:276:
extern wchar_t *wmempcpy (wchar_t *__restrict __s1,
			  const wchar_t *__restrict __s2, size_t __n)
     __THROW;
.../glibc$
