Without this change, it's necessary to send a second savevm-end QMP
command after aborting a snaphsot, before a new savevm-start QMP
command can succeed.
In process_savevm_finalize(), no longer set an error in the abort
scenario. If there already is another error, there's no need to
override it. If canceling was done intentionally, qmp_savevm_end()
is responsible for setting the state now.

For 6.1.0, there were a few changes to the coroutine-sleep API, but
the adaptations in f376b2b ("update and rebase to QEMU v6.1.0") made
a mistake.
Currently, target_close_wait is NULL when passed to
qemu_co_sleep_ns_wakeable(), which further passes it to
qemu_co_sleep(), but there, it is dereferenced when trying to access
the 'to_wake' member:
> Thread 1 "kvm" received signal SIGSEGV, Segmentation fault.
> qemu_co_sleep (w=0x0) at ../util/qemu-coroutine-sleep.c:57
To fix it, create a proper struct and pass its address instead. Also
call qemu_co_sleep_wake unconditionally, because the NULL check (for
the 'to_wake' member) is done inside the function itself.
This patch is based on what the QEMU commits introducing the changes
to the coroutine-sleep API did to the callers in QEMU:
eaee072085 ("coroutine-sleep: allow qemu_co_sleep_wake that wakes nothing")
29a6ea24eb ("coroutine-sleep: replace QemuCoSleepState pointer with struct in the API")

For the io_uring patch, it's not very clear which configurations can
trigger it, but it should be rather uncommon. See qemu commit
be6a166fde652589761cf70471bcde623e9bd72a for a bit more information.

for-7.0 on the qemu-devel list, but didn't make it into the release).
Also took the chance to switch the gluster fix to the version that
made it into upstream.

Only very minor changes needed:
* Most patches in extra (or some version of them) are part of 7.0.0.
* aio_set_fd_handler got an extra parameter, but can just pass NULL
like we did for the related 'poll' parameter. See QEMU commit
826cc32423db2a99d184dbf4f507c737d7e7a4ae for more.
* Add include for qemu/memalign.h in vma.c and vma-writer.c.
* Add reverts for fixups of already reverted 0347a8fd4c ("block/rbd:
implement bdrv_co_block_status") that came in with 7.0.0. Those
fixups are not enough, see Proxmox bugzilla #4047.
* Two trivial context changes for bitmap-mirror patches.
* block_int.h got split up into multiple headers.
* Some context changes in configure and meson.build.
* Used the oppurtunity to squash fixup of bdrv_backuo_dump_create typo
in a later patch into the patch introducing the function (had to
move code to new header during rebase).

Introduce a new map line for skipping a certain drive, of the form
skip=drive-scsi0
Since in PVE, most archives are compressed and piped to vma for
restore, it's not easily possible to skip reads.
For the reader, a new skip flag for VmaRestoreState is added and the
target is allowed to be NULL if skip is specified when registering.
If
the skip flag is set, no writes will be made as well as no check for
duplicate clusters. Therefore, the flag is not set for verify.

It pulls in a lot of stuff via the libglx0 -> libglx-mesa0 dependency
chain, so only suggest it for now to avoid installing it in the
installer or via common "PVE on-top Debian" installations, VirGL
integration is experimental after all and we may drop/replace it with
the vulkan based venus one, once available (Debian 12?).

This is necessary for multi-disk backups where not all jobs are
immediately started after they are created. QEMU commit
06e0a9c16405c0a4c1eca33cf286cc04c42066a2 did already part of the work,
ensuring that new writes after job creation don't pass through to the
backup, but not yet for the MIRROR_SYNC_MODE_BITMAP case which is used
for PBS.

Notable changes:
* bdrv_co_p{discard,readv,writev,write_zeroes} function signatures
changed, to using int64_t for offsets/bytes and some still had int
rather than BrdvRequestFlags for the flags.
* job_cancel_sync now has a force parameter. Commit messages in

sound like using force=true makes more sense.
* Added 3 patches coming in via qemu-stable tag, most important one is
to work around a librbd issue.
* Added another 3 patches from qemu-devel to fix issue leading to
crash when live migrating with iothread.
* cluster_size calculation helper changed (see patch pve/0026).
* QAPI's if conditionals now use 'CONFIG_FOO' rather than
'defined(CONFIG_FOO)'
