In the previous commit e2f93826 ("tests/qemu-iotests/197: add
testcase for CoR with subclusters") we've introduced a new testcase for
copy-on-read with subclusters.  Test 197 always forces qcow2 as the top
image, but allows backing image to be in any format.  That last test
case didn't meet these requirements, so let's fix it by using more
generic "qemu-io -c map" command.

Debian 10 has Python 3.7, so it is not possible to use it anymore
now that Python 3.8 is required.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

importlib.metadata is included in Python 3.8, so there is no
need to fallback to either importlib-metadata or pkgresources
when generating console script shims.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Debian 10 is not anymore a supported distro, since Debian 12 was
released on June 10, 2023.  Our supported build platforms as of today
all support at least 3.8 (and all of them except for Ubuntu 20.04
support 3.9):

openSUSE Leap 15.5: 3.6.15 (3.11.2)
CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16, 3.11.4)
CentOS Stream 9:    3.9.17 (3.11.4)
Fedora 37:          3.11.4
Fedora 38:          3.11.4
Debian 11:          3.9.2
Debian 12:          3.11.2
Alpine 3.14, 3.15:  3.9.16
Alpine 3.16, 3.17:  3.10.10
Ubuntu 20.04 LTS:   3.8.10
Ubuntu 22.04 LTS:   3.10.12
NetBSD 9.3:         3.9.13*
FreeBSD 12.4:       3.9.16
FreeBSD 13.1:       3.9.18
OpenBSD 7.2:        3.9.17

Note: NetBSD does not appear to have a default meta-package, but offers
several options, the lowest of which is 3.7.15. However, "python39"
appears to be a pre-requisite to one of the other packages we request
in tests/vm/netbsd.

Since it is safe under our supported platform policy, bump our
minimum supported version of Python to 3.8.  The two most interesting
features to have by default include:

- the importlib.metadata module, whose lack is responsible for over 100
  lines of code in mkvenv.py

- improvements to asyncio, for example asyncio.CancelledError
  inherits from BaseException rather than Exception

In addition, code can now use the assignment operator ':='

Because mypy now learns about importlib.metadata, a small change to
mkvenv.py is needed to pass type checking.

There are no config-host.mak symbols anymore that are needed in
config-host.h; the only symbols that are included in config_host_data via
the foreach loop are:

- CONFIG_DEFAULT_TARGETS, which is not used by C code.

- CONFIG_TCG and CONFIG_TCG_INTERPRETER, which are not part of config-host.mak

So, list these two symbols explicitly.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Stop applying config-host.mak to the sourcesets, since it does not
have any more CONFIG_* symbols coming from the command line.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

CONFIG_SOLARIS is only used to pick tap implementations.  But the
target OS is invariant and does not depend on the configuration, so move
away from config_host and just use unconditional rules in softmmu_ss.

While the option still needs to be parsed in the configure script
(it's needed by tests/tcg, and also to decide about recursing
into contrib/plugins), passing it to Meson can be done with -D
instead of using config-host.mak.

Treat contrib/plugins the same as the firmware.

The initial reason to write this patch was to remove the last use of
CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG
plugins are unrelated to --enable-debug-tcg, and instead they should
be the same as those used to build emulators (the plugins are not build
via meson for demonstration reasons only).

However, since contrib/plugins/Makefile is also the last case of doing
a compilation job using config-host.mak, go a step further and make it
use a completely separate configuration file, removing all references
to compilers from the toplevel config-host.mak.  Clean up references to
empty variables, and use .SECONDARY so that intermediate object files
are not deleted.

The argument of --host-cc is not obeyed when cross compiling.  To avoid
this issue, place it in a configuration file and pass it to meson
with --native-file.

While at it, clarify that --host-cc is not obeyed anyway when _not_
cross compiling, because cc="$host_cc" is placed before --host-cc is
processed.

$(HOST_CC) is only used to invoke the preprocessor, and $(CC) can be
used instead now that there is a Tricore C compiler.  Remove the variable
from config-host.mak.

Unsupported CPU and OSes are not really going away, but the

Under Darwin, using -shared makes it impossible to have undefined symbols
and -bundle has to be used instead; so detect the OS and use
different options.
