patch v1 add restrict to Linux netdb.h

[Joel Sherrill]

Hi

Attached is a patch to make the netdb.h prototypes
in libc/sys/linux match glibc and SUS.

2013-07-19 Sahil Patnayakuni <sahilp@rtems.org>

     * libc/sys/linux/include/netdb.h, libc/sys/linux/net/getaddrinfo.c,
     libc/sys/linux/net/getnameinfo.c: Add restrict keyword to getnameinfo()
     and getaddrinfo() to increase standards compliance and match glibc.

OK to apply?
