gettimeofday.2: Use restrict in prototypes 

POSIX specifies that the parameters of gettimeofday() shall be
'restrict'.  Glibc uses 'restrict' too.
Let's use it here too.

......

.../glibc$ grep_syscall_wrapper gettimeofday
time/sys/time.h:66:
extern int gettimeofday (struct timeval *__restrict __tv,
			 void *__restrict __tz) __THROW __nonnull ((1));
.../glibc$

function grep_syscall_wrapper()
{
	if ! [ -v 1 ]; then
		>&2 echo "Usage: ${FUNCNAME[0]} <syscall>";
		return ${EX_USAGE};
	fi

	find * -type f \
	|grep '\.h$' \
	|sort -V \
	|xargs pcregrep -Mn \
	  "(?s)^[^\s#][\w\s]+\s+\**${1}\s*\([\w\s()[\]*,]*?(...)?\)[\w\s()]*;" \
	|sed -E 's/^[^:]+:[0-9]+:/&\n/';
}
