network: recvmsg and sendmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int. Also the new recvmsg and sendmsg implementation is only added on libc, with libpthread only containing a compat symbol. Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * conform/data/sys/socket.h-data (msghdr.msg_iovlen): Remove xfail- and change to correct expected type. (msghdr.msg_controllen): Likewise.
