Volker Rümelin 9d30c78c7d meson: reenable filemonitor-inotify compilation
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.

Frédéric Pétrot e9d07601f6 qemu/int128: addition of div/rem 128-bit operations
Addition of div and rem on 128-bit integers, using the 128/64->128 divu and
64x64->128 mulu in host-utils.
These operations will be used within div/rem helpers in the 128-bit riscv
target.

Paolo Bonzini 63a7f85306 meson: fix missing preprocessor symbols
While most libraries do not need a CONFIG_* symbol because the
"when:" clauses are enough, some do.  Add them back or stop
using them if possible.

In the case of libpmem, the statement to add the CONFIG_* symbol
was still in configure, but could not be triggered because it
checked for "no" instead of "disabled" (and it would be wrong anyway
since the test for the library has not been done yet).

Vladimir Sementsov-Ogievskiy 8cad15b156 util: add transactions.c
Add simple transaction API to use in further update of block graph
operations.

Supposed usage is:

- "prepare" is main function of the action and it should make the main
  effect of the action to be visible for the following actions, keeping
  possibility of roll-back, saving necessary things in action state,
  which is prepended to the action list (to do that, prepare func
  should call tran_add()). So, driver struct doesn't include "prepare"
  field, as it is supposed to be called directly.

- commit/rollback is supposed to be called for the list of action
  states, to commit/rollback all the actions in reverse order

- When possible "commit" should not make visible effect for other
  actions, which make possible transparent logical interaction between
  actions.

Lukas Straub 50186051f4 Introduce yank feature
The yank feature allows to recover from hanging qemu by "yanking"
at various parts. Other qemu systems can register themselves and
multiple yank functions. Then all yank functions for selected
instances can be called by the 'yank' out-of-band qmp command.
Available instances can be queried by a 'query-yank' oob command.

Make it possible to compile out the vhost-user-blk server. It is enabled
by default on Linux.

Note that vhost-user-server.c depends on libvhost-user, which requires
CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that
option controls vhost-user frontends (previously known as "master") and
not device backends (previously known as "slave").

Paolo Bonzini a81df1b68b libqemuutil, qapi, trace: convert to meson
This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.

Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a.  Because all of its users required gio
otherwise, the bug was hidden.  Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.
