Add test where sender sends two message, each with own
data pattern. Reader tries to read first to broken buffer:
it has three pages size, but middle page is unmapped. Then,
reader tries to read second message to valid buffer. Test
checks, that uncopied part of first message was dropped
and thus not copied as part of second message.

In `test_no_sockets` we don't expect any sockets, indeed
check_no_sockets() prints an error and exits if `sockets` list is
not empty, so free_sock_stat() call is unnecessary since it would
only be called when the `sockets` list is empty.
This was discovered by a strange warning printed by gcc v11.2.1:
In file included from ../../include/linux/list.h:7,
from vsock_diag_test.c:18:
vsock_diag_test.c: In function ‘test_no_sockets’:
../../include/linux/kernel.h:35:45: error: array subscript ‘struct vsock_stat[0]’ is partly outside array bound
s of ‘struct list_head[1]’ [-Werror=array-bounds]
35 | const typeof(((type *)0)->member) * __mptr = (ptr); \

| ^~~~~~~
../../include/linux/list.h:23:26: note: in definition of macro ‘LIST_HEAD’
23 | struct list_head name = LIST_HEAD_INIT(name)
It seems related to some compiler optimization and assumption
about the empty `sockets` list, since this warning is printed
only with -02 or -O3. Also removing `exit(1)` from
check_no_sockets() makes the warning disappear since in that
case free_sock_stat() can be reached also when the list is
not empty.

Implement two tests of SOCK_SEQPACKET socket: first sends data by
several 'write()'s and checks that number of 'read()' were same.
Second test checks MSG_TRUNC flag. Cases for connect(), bind(),
etc. are not tested, because it is same as for stream socket.

Here are 3 SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your current
tree, that should be trivial to handle (one file modified by two things,
one file deleted.)
All 3 of these have been in linux-next for a while, with no reported
issues other than the merge conflict.

Whenever the server side of vsock is binding to the socket, but not
listening yet, we expect the behavior from the client to be identical to
what happens when the server is not even started.
This new test runs the server side so that it binds to the socket
without ever listening to it. The client side will try to connect and
should receive an ECONNRESET error.
This new test provides a way to validate the previously introduced patch
for making sure the server side will always answer with a RST packet in
case the client requested a new connection.

Before check if a send returns -EPIPE, we need to make sure the
connection is closed.
To do that, we use epoll API to wait EPOLLRDHUP or EPOLLHUP events
on the socket.
