Since commit 4dba278908 ("configure, meson: move CPU_CFLAGS out of
QEMU_CFLAGS"), CPU_CFLAGS is included in the link commands both during
configure and (via config-meson.cross) during meson. It need not be
added separately to QEMU_LDFLAGS.

This partially reverts commit bbd2d5a812.
This commit was misguided and broke using --disable-pie on any distro
that enables PIE by default in their compiler driver, including Debian
and its derivatives. Whilst -no-pie is not a linker flag, it is a
compiler driver flag that ensures -pie is not automatically passed by it
to the linker. Without it, all compile_prog checks will fail as any code
built with the explicit -fno-pie will fail to link with the implicit
default -pie due to trying to use position-dependent relocations. The
only bug that needed fixing was LDFLAGS_NOPIE being used as a flag for
the linker itself in pc-bios/optionrom/Makefile.
Note this does not reinstate exporting LDFLAGS_NOPIE, as it is unused,
since the only previous use was the one that should not have existed. I
have also updated the comment for the -fno-pie and -no-pie checks to
reflect what they're actually needed for.

This patch fixes actually two issues with 'make cscope'.
Firstly, it fixes the command for MacOS "find" command as MacOS will append the
full path of "$(SRC_PATH)/" before each found entry, then after the final "./"
replacement trick it'll look like (e.g., "qapi/qmp-dispatch.c"):
/qapi/qmp-dispatch.c
Which will point to the root directory instead.
Fix it by simply remove the "/" in "$(SRC_PATH)/" of "find-src-path", then
it'll work for at least both Linux and MacOS.
The other OS-independent issue is to start proactively ignoring soft links when
generating tags, otherwise by default on master branch we'll see this error
when "make cscope":
cscope: cannot find file subprojects/libvhost-user/include/atomic.h

Now that we check sysbus device types during device creation, we
can remove the check in the machine init done notifier.
This was the only thing done by this notifier, so we remove the
whole sysbus_notifier structure of the MachineState.
Note: This notifier was checking all /peripheral and /peripheral-anon
sysbus devices. Now we only check those added by -device cli option or
device_add qmp command when handling the command/option. So if there
are some devices added in one of these containers manually (eg in
machine C code), these will not be checked anymore.
This use case does not seem to appear apart from
hw/xen/xen-legacy-backend.c (it uses qdev_set_id() and in this case,
not for a sysbus device, so it's ok).

For example, MSIX-Table size of 82599 NIC is 0x30 and the offset in
Bar 3(size 64KB) is 0x0. vfio_listener_region_add() will be called

Wait for the destination VM to close itself instead of racing to shut it
down first, which produces different error log messages from AQMP
depending on precisely when we tried to shut it down.
(For example: We may try to issue 'quit' immediately prior to the target
VM closing its QMP socket, which will cause an ECONNRESET error to be
logged. Waiting for the VM to exit itself avoids the race on shutdown
behavior.)

AQMP likes to be very chatty about errors it encounters. In general,
this is good because it allows us to get good diagnostic information for
otherwise complex async failures.
For example, during a failed QMP connection attempt, we might see:
+ERROR:qemu.aqmp.qmp_client.qemub-2536319:Negotiation failed: EOFError
+ERROR:qemu.aqmp.qmp_client.qemub-2536319:Failed to establish session: EOFError
This might be nice in iotests output, because failure scenarios
involving the new QMP library will be spelled out plainly in the output
diffs.
For tests that are intentionally causing this scenario though, filtering
that log output could be a hassle. For now, add a context manager that
simply lets us toggle this output off during a critical region.
(Additionally, a forthcoming patch allows the use of either legacy or
async QMP to be toggled with an environment variable. In this
circumstance, we can't amend the iotest output to just always expect the
error message, either. Just suppress it for now. More rigorous log
filtering can be investigated later if/when it is deemed safe to
permanently replace the legacy QMP library.)

To use the AQMP backend, Machine just needs to be a little more diligent
about what happens when closing a QMP connection. The operation is no
longer a freebie in the async world; it may return errors encountered in
the async bottom half on incoming message receipt, etc.
(AQMP's disconnect, ultimately, serves as the quiescence point where all
async contexts are gathered together, and any final errors reported at
that point.)
Because async QMP continues to check for messages asynchronously, it's
almost certainly likely that the loop will have exited due to EOF after
issuing the last 'quit' command. That error will ultimately be bubbled
up when attempting to close the QMP connection. The manager class here
then is free to discard it -- if it was expected.

If we spy on the QMP commands instead, we don't need callers to remember
to pass it. Seems like a fair trade-off.
The one slightly weird bit is overloading this instance variable for
wait(), where we use it to mean "don't issue the qmp 'quit'
command". This means that wait() will "fail" if the QEMU process does
not terminate of its own accord.
In most cases, we probably did already actually issue quit -- some
iotests do this -- but in some others, we may be waiting for QEMU to
terminate for some other reason, such as a test wherein we tell the
guest (directly) to shut down.

This one is insidious: if you write an import as "from {namespace}
import {subpackage}" as mirror-top-perms (now) does, mypy will fail on
every-other invocation *if* the package being imported is a typed,
installed, namespace-scoped package.
Upsettingly, that's exactly what 'qemu.[aqmp|qmp|machine]' et al are in
the context of Python CI tests.
Now, I could just edit mirror-top-perms to avoid this invocation, but
since I tripped on a landmine, I might as well head it off at the pass
and make sure nobody else trips on that same landmine.
It seems to have something to do with the order in which files are
checked as well, meaning the random order in which set(os.listdir())
produces the list of files to test will cause problems intermittently
and not just strictly "every other run".
This will be fixed in mypy >= 0.920, which is not released yet. The
workaround for now is to disable incremental checking, which avoids the
issue.
Note: This workaround is not applied when running iotest 297 directly,
because the bug does not surface there! Given the nature of CI jobs not
starting with any stale cache to begin with, this really only has a
half-second impact on manual runs of the Python test suite when executed
directly by a developer on their local machine. The workaround may be
removed when the Python package requirements can stipulate mypy 0.920 or
higher, which can happen as soon as it is released. (Barring any
unforseen compatibility issues that 0.920 may bring with it.)

Take iotest 297's main() test function and split it into two sub-cases
that can be skipped individually. We can also drop custom environment
setup from the pylint test as it isn't needed.

As mentioned in 'iotests/297: Don't rely on distro-specific linter
binaries', these checks are overly strict. Update them to be in-line
with how we actually invoke the linters themselves.

Instead of using a process return code as the python function return
value (or just not returning anything at all), allow run_linter() to
raise an exception instead.
The responsibility for printing output on error shifts from the function
itself to the caller, who will know best how to present/format that
information. (Also, "suppress_output" is now a lot more accurate of a
parameter name.)

There's virtually nothing special here anymore; we can combine these
into a single, rather generic function.

Move environment setup into main(), and split the actual linter
execution into run_pylint and run_mypy, respectively.

'pylint-3' is another Fedora-ism. Use "python3 -m pylint" or "python3 -m
mypy" to access these scripts instead. This style of invocation will
prefer the "correct" tool when run in a virtual environment.
Note that we still check for "pylint-3" before the test begins -- this
check is now "overly strict", but shouldn't cause anything that was
already running correctly to start failing. This is addressed by a
commit later in this series;
'iotests/297: update tool availability checks'.

Instead of running "run_linters" directly, create a main() function that
will be responsible for environment setup, leaving run_linters()
responsible only for execution of the linters.
(That environment setup will be moved over in forthcoming commits.)

Move --score=n and --notes=XXX,FIXME into pylintrc. This pulls
configuration out of code, which I think is probably a good thing in
general.
