2d804f55b4 iotests/297: Split run_linters apart into run_pylint and run_mypy
Move environment setup into main(), and split the actual linter
execution into run_pylint and run_mypy, respectively.

f1be6219c5 iotests/297: Don't rely on distro-specific linter binaries
'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'.

447aebda3f iotests/297: Create main() function
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.)

This migration could not be completed when out of order(OOO) CQ event occurs.
The send queue and receive queue shared a same completion queue, and
qemu_rdma_block_for_wrid() will drop the CQs it's not interested in. But
the dropped CQs by qemu_rdma_block_for_wrid() could be later CQs it wants.
So in this case, qemu_rdma_block_for_wrid() will block forever.

OOO cases will occur in both source side and destination side. And a
forever blocking happens on only SEND and RECV are out of order. OOO between
'WRITE RDMA' and 'RECV' doesn't matter.

below the OOO sequence:
       source                             destination
      rdma_write_one()                   qemu_rdma_registration_handle()
1.    S1: post_recv X                    D1: post_recv Y
2.    wait for recv CQ event X
3.                                       D2: post_send X     ---------------+
4.                                       wait for send CQ send event X (D2) |
5.    recv CQ event X reaches (D2)                                          |
6.  +-S2: post_send Y                                                       |
7.  | wait for send CQ event Y                                              |
8.  |                                    recv CQ event Y (S2) (drop it)     |
9.  +-send CQ event Y reaches (S2)                                          |
10.                                      send CQ event X reaches (D2)  -----+
11.                                      wait recv CQ event Y (dropped by (8))

Although a hardware IB works fine in my a hundred of runs, the IB specification
doesn't guaratee the CQ order in such case.

Here we introduce a independent send completion queue to distinguish
ibv_post_send completion queue from the original mixed completion queue.
It helps us to poll the specific CQE we are really interested in.

92d1d3ada1 hw/intc/sh_intc: Drop another useless macro
The INT_REG_PARAMS macro was only used a few times within one function
on adjacent lines and is actually more complex than writing out the
parameters so simplify it by expanding the macro at call sites and
dropping the #define.

3cf7ce4337 hw/char/sh_serial: Do not abort on invalid access
Replace fprintf with qemu_log_mask LOG_GUEST_ERROR as the intention is
to handle valid accesses in these functions so if we get to these
errors then it's an invalid access. Do not abort as that would allow
the guest to crash QEMU and the practice in other devices is to not do
that just log and ignore the invalid access. While at it also simplify
the complex bit ops to check if a return value was set which can be
done much simpler and clearer.

57df0dff1a qapi: Extend -compat to set policy for unstable interfaces
New option parameters unstable-input and unstable-output set policy
for unstable interfaces just like deprecated-input and
deprecated-output set policy for deprecated interfaces (see commit
6dd75472d5 "qemu-options: New -compat to set policy for deprecated
interfaces").  This is intended for testing users of the management
interfaces.  It is experimental.

For now, this covers only syntactic aspects of QMP, i.e. stuff tagged
with feature 'unstable'.  We may want to extend it to cover semantic
aspects, or the command line.

Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output
of query-qmp-schema or query-command-line-options.  Tolerable, because
it's meant for testing.  If running with -compat fails, skip the test.
