Thomas Huth 95c0b77018 tests/qtest/cdrom-test: Check whether devices are available before using them 
Downstream users might want to disable legacy devices in their binaries,
so we should not blindly assume that they are available. Add some proper
checks before using them.

Thomas Huth 9cbd66028b tests/qtest: Improve endianness-test to work with missing machines and devices 
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.

Thomas Huth 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.

Thomas Huth 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.

WANG Xuerui 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.

Vladimir Sementsov-Ogievskiy 9e14491af4 nbd/client-connection: improve error message of cancelled attempt

Vladimir Sementsov-Ogievskiy 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.
