Adhemerval Zanella af7f7c7ec8 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.
