The way that BUSY + PxCI is cleared for NCQ (FPDMA QUEUED) commands is
described in SATA 3.5a Gold:
11.15 FPDMA QUEUED command protocol
DFPDMAQ2: ClearInterfaceBsy
"Transmit Register Device to Host FIS with the BSY bit cleared to zero
and the DRQ bit cleared to zero and Interrupt bit cleared to zero to
mark interface ready for the next command."
PxCI is currently cleared by handle_cmd(), but we don't write the D2H
FIS to the FIS Receive Area that actually caused PxCI to be cleared.
Similar to how ahci_pio_transfer() calls ahci_write_fis_pio() with an
additional parameter to write a PIO Setup FIS without raising an IRQ,
add a parameter to ahci_write_fis_d2h() so that ahci_write_fis_d2h()
also can write the FIS to the FIS Receive Area without raising an IRQ.
Change process_ncq_command() to call ahci_write_fis_d2h() without
raising an IRQ (similar to ahci_pio_transfer()), such that the FIS
Receive Area is in sync with the PxTFD shadow register.
E.g. Linux reads status and error fields from the FIS Receive Area
directly, so it is wise to keep the FIS Receive Area and the PxTFD
shadow register in sync.

Currently, the first time sending an unsupported command
(e.g. READ LOG DMA EXT) will not have ERR_STAT set in the completion.
Sending the unsupported command again, will correctly have ERR_STAT set.
When ide_cmd_permitted() returns false, it calls ide_abort_command().
ide_abort_command() first calls ide_transfer_stop(), which will call
ide_transfer_halt() and ide_cmd_done(), after that ide_abort_command()
sets ERR_STAT in status.
ide_cmd_done() for AHCI will call ahci_write_fis_d2h() which writes the
current status in the FIS, and raises an IRQ. (The status here will not
have ERR_STAT set!).
Thus, we cannot call ide_transfer_stop() before setting ERR_STAT, as
ide_transfer_stop() will result in the FIS being written and an IRQ
being raised.
The reason why it works the second time, is that ERR_STAT will still
be set from the previous command, so when writing the FIS, the
completion will correctly have ERR_STAT set.
Set ERR_STAT before writing the FIS (calling cmd_done), so that we will
raise an error IRQ correctly when receiving an unsupported command.

It is true, that there is no problem during runtime
from the first sight, because the memory is lost just
before qemu exits. Nevertheless, this change is necessary,
because AddressSanitizer is not able to recognize this
situation and produces crash-report (which is
false-positive in fact). Lots of False-Positive warnings
are davaluing problems, found with fuzzing, and thus the
whole methodology of dynamic analysis.
This patch eliminates such False-Positive reports,
and makes every problem, found with fuzzing, more valuable.

Currently, when using `-display dbus,gl=on` all updates to the client
become "full scanout" updates, meaning there is no way for the client to
limit damage regions to the display server.
Instead of using an "update count", this patch tracks the damage region
and propagates it to the client.
This was less of an issue when clients were using GtkGLArea for
rendering,
as you'd be doing full-surface redraw. To be efficient, the client needs
both a DMA-BUF and the damage region to be updated.

shared the VC console parse handler with GTK. And later on in commit
d8aec9d9 ("display: add -display spice-app launching a Spice client"),
I also used it to handle spice-app VC.
This is not necessary, the VC console options (width/height/cols/rows)
are specific, and unused by tty-level GTK/Spice VC.

As of now, the code didn't reach a NULL timer because dpy_set_ui_info()
checks if dpy_ui_info_supported() (hw_ops->ui_info != NULL), which is
false for text_console_ops. This is a bit fragile, let simply allocate
