Avoid polluting the compilation of common-user/ with local include files;
making an include file available to common-user/ should be a deliberate
decision in order to keep a clear interface that can be used by both
bsd-user/ and linux-user/.

It is not necessary to have a separate static_library just for common_user
files; using the one that already covers the rest of common_ss is enough
unless you need to reuse some source files between emulators and tests.
Just place common files for all user-mode emulators in common_ss,
similar to what is already done for softmmu_ss in full system emulators.

The only disadvantage is that the include_directories under bsd-user/include/
and linux-user/include/ are now enabled for all targets rather than only
user mode emulators.  This however is not different from how include/sysemu/
is available when building user mode emulators.

From: Thomas Huth <thuth@redhat.com>

The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

--dynamic-list is present on all supported ELF (not Windows or Darwin)
platforms, since it dates back to 2006; -exported_symbols_list is
likewise present on all supported versions of macOS.  Do not bother
doing a functional test in configure.

Remove the file creation from configure as well: for Darwin, move the
the creation of the Darwin-formatted symbols to meson; for ELF, use the
file in the source path directly and switch from -Wl, to -Xlinker to
not break weird paths that include a comma.

Similar to other optional features, leave the variables empty and compute
the actual value later.  Use the existence of include or source directories
to detect whether an OS or CPU supports respectively bsd-user and linux-user.

For now, BSD user-mode emulation is buildable even on TCI-only
architectures.  This probably will change once safe signals are
brought over from linux-user.

These files have been removed for more than year in the best
case, or for more than ten years for some really old TCG files.
Remove any traces of it.

Always include the STRIP variable in config-host.mak (it's only used
by the s390-ccw firmware build, and it adds a default if configure
omitted it), and use meson-buildoptions.sh to turn
--enable/--disable-strip into -Dstrip.

The default is now not to strip the binaries like for almost every other
package that has a configure script.

This will be needed as soon as config-poison.h moves from configure to
a meson custom_target (which is built at "ninja" time).

This allows to make PDPTRs part of the migration
stream and thus not reload them after migration which
is against X86 spec.

This is unnecessary, because the interrupt would be retrieved and queued
anyway by KVM_GET_VCPU_EVENTS and KVM_SET_VCPU_EVENTS respectively,
and it makes the flow more similar to the one for KVM_GET/SET_SREGS2.

If roms/seabios/Makefile is not present, the configure script
is not creating the roms/seabios directory anymore (commit
5dce7b8d8c, "configure: remove DIRS", 2021-12-18); thus, creating
roms/seabios/config.mak fails.

The easiest thing to do is to not create the file, since it will not
be used.

With more recent versions of Meson, the build.ninja file is more selective
as to what is built by default, and not building the modules results in test
failures.

Mark the modules as built-by-default and, to make the dependencies more
precise, also require them to be up-to-date before running tests.

  To: qemu-devel; +Cc: Volker Rümelin

From: Volker Rümelin <vr_qemu@t-online.de>

Reenable util/filemonitor-inotify compilation. Compilation was
disabled when commit a620fbe9ac ("configure: convert compiler tests
to meson, part 5") moved CONFIG_INOTIFY1 from config-host.mak to
config-host.h.

This fixes the usb-mtp device and reenables test-util-filemonitor.

Fixes: a620fbe9ac ("configure: convert compiler tests to meson, part 5")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/800

This breaks the centos-stream-8-x86_64 job:
https://gitlab.com/qemu-project/qemu/-/jobs/1959569820

because the commit "block/file-posix: Simplify the XFS_IOC_DIOINFO handling"
removes the configure --disable-xfsctl option, but that job's config
is still using it (looks like we set this up in the file
scripts/ci/org.centos/stream/8/x86_64/configure)

'git grep xfsctl' shows that scripts/coverity-scan/run-coverity-scan
is also still using --enable-xfsctl, which has similarly
been removed by that commit.

thanks
