e63ed64c6d tests/qtest/virtio-net-failover: Use g_file_open_tmp() to create temporary file
g_test_rand_int() must not be called before g_test_init(), otherwise
the glib will show a "g_rand_int: assertion 'rand != NULL' failed"
message in the log. So we could change the order here, but actually,
it's safer to use g_file_open_tmp() anyway, so let's use that function
now instead.

The users might have built QEMU with less machines or without the
i82378 superio device. Add some checks to the endianess-test so that
it is able to deal with such stripped down QEMU versions, too.

ad9e129b01 tests/qtest: Add a function that checks whether a device is available
Devices might not always be compiled into the QEMU target binaries.
We already have the libqos framework that is good for handling such
situations, but some of the qtests are not a real good fit for the
libqos framework. Let's add a qtest_has_device() function for such
tests instead.

31fb263c29 tests/qtest: Make the filter tests independent from a specific NIC
These filter tests need a NIC, no matter which one, so they use a common
NIC by default. However, these common NIC models might not always have
been compiled into the QEMU target binary, so assuming that a certain NIC
is available is a bad idea. Since the exact type of NIC does not really
matter for these tests, let's switch to "-nic" instead of "-netdev" so
that QEMU can simply pick a default NIC for us.
This way we can now run the tests on other targets that have a default
machine with an on-board/default NIC, too.

dfcf900ba6 configure, meson.build: Mark support for loongarch64 hosts
Example output of `uname -a` on an initial Gentoo LA64 port, running
the upstream submission version of Linux (with some very minor patches
not influencing output here):

> Linux <hostname> 5.14.0-10342-g37a00851b145 #5 SMP PREEMPT Tue Aug 10 12:56:24 PM CST 2021 loongarch64 GNU/Linux

And the same on the vendor-supplied Loongnix 20 system, with an early
in-house port of Linux, and using the old-world ABI:

> Linux <hostname> 4.19.167-rc5.lnd.1-loongson-3 #1 SMP Sat Apr 17 07:32:32 UTC 2021 loongarch64 loongarch64 loongarch64 GNU/Linux

So a name of "loongarch64" matches both, fortunately.

169b9a94ed nbd/client-connection: nbd_co_establish_connection(): return real error
The only caller of nbd_do_establish_connection() that uses errp is
nbd_open(). The only way to cancel this call is through open_timer
timeout. And for this case, user will be more interested in description
of last failed connect rather than in
"Connection attempt cancelled by other operation".

So, let's change behavior on cancel to return previous failure error if
available.

Do the same for non-blocking failure case. In this case we still don't
have a caller that is interested in errp. But let's be consistent.
