hw/scsi/megasas: Use uint32_t for reply queue head/tail values
While the reply queue values fit in 16-bit, they are accessed
as 32-bit:
661: s->reply_queue_head = ldl_le_pci_dma(pcid, s->producer_pa);
662: s->reply_queue_head %= MEGASAS_MAX_FRAMES;
663: s->reply_queue_tail = ldl_le_pci_dma(pcid, s->consumer_pa);
664: s->reply_queue_tail %= MEGASAS_MAX_FRAMES;
Having:
41:#define MEGASAS_MAX_FRAMES 2048 /* Firmware limit at 65535 */
In order to update the ld/st*_pci_dma() API to pass the address
of the value to access, it is simpler to have the head/tail declared
as 32-bit values. Replace the uint16_t by uint32_t, wasting 4 bytes in
the MegasasState structure.

blockjob: drop BlockJob.blk field
It's unused now (except for permission handling)[*]. The only reasonable
user of it was block-stream job, recently updated to use own blk. And
other block jobs prefer to use own source node related objects.
So, the arguments of dropping the field are:
- block jobs prefer not to use it
- block jobs usually has more then one node to operate on, and better
to operate symmetrically (for example has both source and target
blk's in specific block-job state structure)
*: BlockJob.blk is used to keep some permissions. We simply move
permissions to block-job child created in block_job_create() together
with blk.
In mirror, we just should not care anymore about restoring state of
blk. Most probably this code could be dropped long ago, after dropping
bs->job pointer. Now it finally goes away together with BlockJob.blk
itself.
iotest 141 output is updated, as "bdrv_has_blk(bs)" check in
qmp_blockdev_del() doesn't fail (we don't have blk now). Still, new
error message looks even better.
In iotest 283 we need to add a job id, otherwise "Invalid job ID"
happens now earlier than permission check (as permissions moved from
blk to block-job node).

use subdirectories TEST_DIR/testname/ and SOCK_DIR/testname/
instead of simply TEST_DIR and SOCK_DIR
2. multiprocessing.Pool.starmap function doesn't support passing

configure, meson.build: Mark support for loongarch64 hosts
Example output of `uname -a` on an initial Gentoo LA64 port, running
the upstream submission version of Linux (with some very minor patches
not influencing output here):
> Linux <hostname>
5.14.0-10342-g37a00851b145 #5 SMP PREEMPT Tue Aug 10 12:56:24 PM CST 2021 loongarch64 GNU/Linux
And the same on the vendor-supplied Loongnix 20 system, with an early
in-house port of Linux, and using the old-world ABI:
> Linux <hostname> 4.19.167-rc5.lnd.1-loongson-3 #1 SMP Sat Apr 17 07:32:32 UTC 2021 loongarch64 loongarch64 loongarch64 GNU/Linux
So a name of "loongarch64" matches both, fortunately.

nbd/client-connection: nbd_co_establish_connection(): return real error
The only caller of nbd_do_establish_connection() that uses errp is
nbd_open(). The only way to cancel this call is through open_timer
timeout. And for this case, user will be more interested in description
of last failed connect rather than in
"Connection attempt cancelled by other operation".
So, let's change behavior on cancel to return previous failure error if
available.
Do the same for non-blocking failure case. In this case we still don't
have a caller that is interested in errp. But let's be consistent.

ui: add a D-Bus display backend
The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0
org.qemu.Display1.Console interface - - -

.Head property u 0 emits-change

.Label property s "VGA" emits-change

It was decoupled from QEMU own gl-blocking mechanism, but that

An extra block/unblock is added arount dpy_gl_update() so existing
