839866fcbd tests/tcg: re-enable threadcount for sh4
This test was marked as broken due to bug #856 which was fixed by
ab419fd8a0 (target/sh4: Fix TB_FLAG_UNALIGN). Local testing shows this
is solid now so lets re-enable the test.

500f73b1aa tests/avocado: disable sh4 rd2 tests on Gitlab
Running repeated invocations on a number of test boxes show a fairly
high error rate:

  $ retry.py -n 100 -c -- ./tests/venv/bin/avocado run tests/avocado/boot_linux_console.py:BootLinuxConsole.test_sh4_r2d
  retry.py called with ['./tests/venv/bin/avocado', 'run', 'tests/avocado/boot_linux_console.py:BootLinuxConsole.test_sh4_r2d']
  Results:
  Run, Ret, Pass/Fail, Time, Total Pass, Total Run
  ...
  Results summary:
  0: 94 times (94.00%), avg time 2.254 (0.00 varience/0.04 deviation)
  1: 3 times (3.00%), avg time 1.837 (0.02 varience/0.14 deviation)
  8: 3 times (3.00%), avg time 91.288 (0.02 varience/0.15 deviation)

Examining the logs they fall into various categories of un-handled
unaligned access by user space and unexpected FPU usage by the kernel
which ultimately lead to the failure to reach the login prompt. This
could be bugs in the translator that only get hit occasionally or just
a flaky kernel - its hard to tell. To avoid these failures gating CI
lets skip on GitLab.

cc45d25c65 tests/avocado: raspi2_initrd: Wait for guest shutdown message before stopping
The avocado test
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_arm_raspi2_initrd
finishes with

    exec_command(self, 'halt')
    # Wait for VM to shut down gracefully
    self.vm.wait()

In theory this should be fine. In practice it runs into two bugs:

 * when the test calls self.vm.wait() Avocado closes the socket
   connection to the guest serial console immediately, so the
   avocado logs don't have the last part of the guest output:
   https://gitlab.com/qemu-project/qemu/-/issues/1265
 * when the socket is closed, a bug in the QEMU socket chardev
   means that it loses any data that the guest UART has not
   yet consumed. This means that the guest doesn't always read
   the full 'halt' command string, so the test intermittently
   fails with a timeout:
   https://gitlab.com/qemu-project/qemu/-/issues/1264

Work around both of these by waiting for the guest to print the
string that means it has completed the shutdown process.  This fixes
a very long standing intermittent failure in this test.

48fad83ff4 MAINTAINERS: add entries for the key build bits
Changes to the build files are a bit special in that they usually go
through other maintainer trees. However considering the build system
is the root of everything a developer is likely to do we should at
least set it out in MAINTAINERS.

I'm going to nominate Paolo for meson stuff given the conversion was
his passion project. I'm happy to cast an eye over configure stuff
considering a lot of the cross compile logic is in there anyway.

c2632994e9 block/vvfat: Unify the mkdir() call

glib provides a portable g_mkdir() API and we can use it to unify

b4c82b1b4d tests/docker: Add flex/bison to debian-hexagon-cross
debian-hexagon-cross contains two images, one to build the toolchain
used for building the Hexagon tests themselves, and one image to build
QEMU and run the tests.

This commit adds flex/bison to the final image that builds QEMU so that
it can also build idef-parser.

Note: This container is not built by the CI and needs to be rebuilt and
updated manually.

6c32fc0df9 block/blkio: Make driver nvme-io_uring take a "path" instead of a "filename"
The nvme-io_uring driver expects a character special file such as
/dev/ng0n1. Follow the convention of having a "filename" option when a
regular file is expected, and a "path" option otherwise.

This makes io_uring the only libblkio-based driver with a "filename"
option, as it accepts a regular file (even though it can also take a
block special file).

4c8f4fda05 block/blkio: Tolerate device size changes
Some libblkio drivers may be able to work with regular files (e.g.,
io_uring) or otherwise resizable devices. Conservatively set
BlockDriver::has_variable_length to true to ensure bdrv_nb_sectors()
always gives up-to-date results.

Also implement BlockDriver::bdrv_co_truncate for the case where no
preallocation is needed and the device already has a size compatible
with what was requested.

5107fd3eff net/vhost-vdpa.c: Fix clang compilation failure
Commit 8801ccd050 introduced a compilation failure with clang
version 10.0.0-4ubuntu1:

../../net/vhost-vdpa.c:654:16: error: variable 'vdpa_device_fd' is
used uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
    } else if (opts->has_vhostfd) {
               ^~~~~~~~~~~~~~~~~
../../net/vhost-vdpa.c:662:33: note: uninitialized use occurs here
    r = vhost_vdpa_get_features(vdpa_device_fd, &features, errp);
                                ^~~~~~~~~~~~~~
../../net/vhost-vdpa.c:654:12: note: remove the 'if' if its condition
is always true
    } else if (opts->has_vhostfd) {
           ^~~~~~~~~~~~~~~~~~~~~~~
../../net/vhost-vdpa.c:629:23: note: initialize the variable
'vdpa_device_fd' to silence this warning
    int vdpa_device_fd;
                      ^
                       = 0
1 error generated.

It's a false positive -- the compiler doesn't manage to figure out
that the error checks further up mean that there's no code path where
vdpa_device_fd isn't initialized.  Put another way, the problem is
that we check "if (opts->has_vhostfd)" when in fact that condition
must always be true.  A cleverer static analyser would probably warn
that we were checking an always-true condition.

Fix the compilation failure by removing the unnecessary if().

Fixes: 8801ccd050 ("vhost-vdpa: allow passing opened vhostfd to vhost-vdpa")
