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.
