There was an issue with SO_LINGER: instead of blocking until all queued
messages for the socket have been successfully sent (or the linger timeout
has been reached), close() would block until packets were handled by the
peer.
Add a test to alert on close() lingering when it should not.

In the sigpipe test, we expect send() to fail, but we do not check if
send() fails with the errno we expect (EPIPE).
Add this check and repeat the send() in case of EINTR as we do in other
tests.

When the other peer calls shutdown(SHUT_RD), there is a chance that
the send() call could occur before the message carrying the close
information arrives over the transport. In such cases, the send()
might still succeed. To avoid this race, let's retry the send() call
a few times, ensuring the test is more reliable.
Sleep a little before trying again to avoid flooding the other peer
and filling its receive buffer, causing false-negative.

The timeout API uses signals, so we have documented not to use sleep(),
but we can use nanosleep(2) since POSIX.1 explicitly specifies that it
does not interact with signals.
Let's provide timeout_usleep() for that.

These tests:
"SOCK_STREAM ioctl(SIOCOUTQ) 0 unsent bytes"
"SOCK_SEQPACKET ioctl(SIOCOUTQ) 0 unsent bytes"
output: "Unexpected 'SIOCOUTQ' value, expected 0, got 64 (CLIENT)".
They test that the SIOCOUTQ ioctl reports 0 unsent bytes after the data
have been received by the other side. However, sometimes there is a delay
in updating this "unsent bytes" counter, and the test fails even though
the counter properly goes to 0 several milliseconds later.
The delay occurs in the kernel because the used buffer notification
callback virtio_vsock_tx_done(), called upon receipt of the data by the
other side, doesn't update the counter itself. It delegates that to
a kernel thread (via vsock->tx_work). Sometimes that thread is delayed
more than the test expects.
Change the test to poll SIOCOUTQ until it returns 0 or a timeout occurs.

This happens on 64-bit big-endian machines.
SO_RCVLOWAT requires an int parameter. However, instead of int, the test
uses unsigned long in one place and size_t in another. Both are 8 bytes
long on 64-bit machines. The kernel, having received the 8 bytes, doesn't
test for the exact size of the parameter, it only cares that it's >=
sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on
a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT
returns with success and the socket stays with the default SO_RCVLOWAT = 1,
which results in vsock_test failures, while vsock_perf doesn't even notice
that it's failed to change it.

This adds test which checks case when data of newly received skbuff is
appended to the last skbuff in the socket's queue. It looks like simple

appends one received skbuff to another. Test checks that this feature
works correctly.
This test is actual only for virtio transport.

This adds SOCK_STREAM and SOCK_SEQPACKET tests for invalid buffer case.
It tries to read data to NULL buffer (data already presents in socket's
queue), then uses valid buffer. For SOCK_STREAM second read must return
data, because skbuff is not dropped, but for SOCK_SEQPACKET skbuff will
be dropped by kernel, and 'recv()' will return EAGAIN.
