74518fb615 q800: add default vendor and product information for scsi-cd devices
The MacOS CDROM driver uses a SCSI INQUIRY command to check that any SCSI CDROMs
detected match a whitelist of vendors and products before adding them to the
list of available devices.

Add known-good default vendor and product information using the existing
compat_prop mechanism so the user doesn't have to use long command lines to set
the qdev properties manually.

356c4c441e scsi-disk: allow MODE SELECT block descriptor to set the block size
The MODE SELECT command can contain an optional block descriptor that can be used
to set the device block size. If the block descriptor is present then update the
block size on the SCSI device accordingly.

This allows CDROMs to be used with A/UX which requires a CDROM drive which is
capable of switching from a 2048 byte sector size to a 512 byte sector size.

4536fba00a scsi-disk: allow the MODE_PAGE_R_W_ERROR AWRE bit to be changeable for CDROM drives
A/UX sends a MODE_PAGE_R_W_ERROR command with the AWRE bit set to 0 when enumerating
CDROM drives. Since the bit is currently hardcoded to 1 then indicate that the AWRE
bit can be changed (even though we don't care about the value) so that
the MODE_PAGE_R_W_ERROR page can be set successfully.

389e18eb9a scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_TRUNCATED quirk for Macintosh
When A/UX configures the CDROM device it sends a truncated MODE SELECT request
for page 1 (MODE_PAGE_R_W_ERROR) which is only 6 bytes in length rather than
10. This seems to be due to bug in Apple's code which calculates the CDB message
length incorrectly.

The work at [1] suggests that this truncated request is accepted on real
hardware whereas in QEMU it generates an INVALID_PARAM_LEN sense code which
causes A/UX to get stuck in a loop retrying the command in an attempt to succeed.

Alter the mode page request length check so that truncated requests are allowed
if the SCSI_DISK_QUIRK_MODE_PAGE_TRUNCATED quirk is enabled, whilst also adding a
trace event to enable the condition to be detected.

09274de1f7 scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk for Macintosh
Both MacOS and A/UX make use of vendor-specific MODE SELECT commands with PF=0
to identify SCSI devices:

- MacOS sends a MODE SELECT command with PF=0 for the MODE_PAGE_VENDOR_SPECIFIC
  (0x0) mode page containing 2 bytes before initialising a disk

- A/UX (installed on disk) sends a MODE SELECT command with PF=0 during SCSI
  bus enumeration, and gets stuck in an infinite loop if it fails

Add a new SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk to allow both
PF=0 MODE SELECT commands and implement a MODE_PAGE_VENDOR_SPECIFIC (0x0)
mode page which is compatible with MacOS.

f43c2b94cd scsi-disk: add SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk for Macintosh
During SCSI bus enumeration A/UX sends a MODE SENSE command to the CDROM with
the DBD bit unset and expects the response to include a block descriptor. As per
the latest SCSI documentation, QEMU currently force-disables the block
descriptor for CDROM devices but the A/UX driver expects the requested block
descriptor to be returned.

If the block descriptor is not returned in the response then A/UX becomes
confused, since the block descriptor returned in the MODE SENSE response is
used to generate a subsequent MODE SELECT command which is then invalid.

Add a new SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk to allow this behaviour
to be enabled as required. Note that an additional workaround is required for
the previous SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk which must never
return a block descriptor even though the DBD bit is left unset.

09d3786762 scsi-disk: add MODE_PAGE_APPLE_VENDOR quirk for Macintosh
One of the mechanisms MacOS uses to identify CDROM drives compatible with MacOS
is to send a custom MODE SELECT command for page 0x30 to the drive. The
response to this is a hard-coded manufacturer string which must match in order
for the CDROM to be usable within MacOS.

Add an implementation of the MODE SELECT page 0x30 response guarded by a newly
defined SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk bit so that CDROM drives
attached to non-Apple machines function exactly as before.

cf60ccc330 cutils: Introduce bundle mechanism
Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.

It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.

Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.

713911a107 ui/cocoa: Fix switched_to_fullscreen warning
I noticed this error while building QEMU on Mac OS X:

    ../ui/cocoa.m:803:17: warning: variable 'switched_to_fullscreen' set but not used [-Wunused-but-set-variable]
        static bool switched_to_fullscreen = false;
                    ^
    1 warning generated.

I think the behavior is fine if you remove "switched_to_fullscreen", I can
still switch in and out of mouse grabbed mode and fullscreen mode with this
change, and Command keycodes will only be passed to the guest if the mouse
is grabbed, which I think is the right behavior. I'm not sure why a static
piece of state was needed to handle that in the first place. Perhaps the
refactoring of the flags-state-change fixed that by toggling the Command
keycode on.

I tested this with an Ubuntu core image on macOS 12.4

85c4bf8aa6 vl: Unlink absolute PID file path
After writing the PID file, we register an exit notifier to unlink it
when the process terminates.  However, if the process has changed its
working directory in the meantime (e.g. in os_setup_post() when
daemonizing), this will not work when the PID file path was relative.
Therefore, pass the absolute path (created with realpath()) to the
unlink() call in the exit notifier.

(realpath() needs a path pointing to an existing file, so we cannot use
it before qemu_write_pidfile().)

Reproducer:
$ cd /tmp
$ qemu-system-x86_64 --daemonize --pidfile qemu.pid
$ file qemu.pid
qemu.pid: ASCII text
$ kill $(cat qemu.pid)
$ file qemu.pid
qemu.pid: ASCII text

(qemu.pid should be gone after the process has terminated.)

compatibility with both pre- and post-0.950 mypy versions.
