This adds three tests for MSG_ZEROCOPY feature:
1) SOCK_STREAM tx with different buffers.
2) SOCK_SEQPACKET tx with different buffers.
3) SOCK_STREAM test to read empty error queue of the socket.
Patch also works as preparation for the next patches for tools in this
patchset: vsock_perf and vsock_uring_test:
1) Adds several new functions to util.c - they will be also used by
vsock_uring_test.
2) Adds two new functions for MSG_ZEROCOPY handling to a new source
file - such source will be shared between vsock_test, vsock_perf and
vsock_uring_test, thus avoiding code copy-pasting.
