This change moves the code that connects the SoC UART's to serial_hd's
to the machine.
It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.
This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.
This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.
I tested this using the images and commands from the previous
refactoring, and another test image for the ast1030:

To support multiple SoC's running simultaneously, we need a unique name for
each RAM region. DRAM is created by the machine, but SRAM is created by the
SoC, since in hardware it is part of the SoC's internals.
We need a way to uniquely identify each SRAM region though, for VM
migration. Since each of the SoC's CPU's has an index which identifies it
uniquely from other CPU's in the machine, we can use the index of any of the
CPU's in the SoC to uniquely identify differentiate the SRAM name from other
SoC SRAM's. In this change, I just elected to use the index of the first CPU
in each SoC.

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.

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.

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

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

With semihosting_get_arg, we already have a check vs argc, so
there's no point replicating it -- just check the result vs NULL.
Merge copy_argn_to_target into its caller.

Always log the assert locally. Do not report_fault, but
instead include the fact of the fault in the assertion.
Don't bother freeing allocated strings before the abort().

Use semihost_sys_write and/or qemu_semihosting_console_write
for implementing plog. When using gdbstub, copy the temp
string below the stack so that gdb has a guest address from
which to perform the log.

This separates guest file descriptors from host file descriptors,

We don't implement it with _WIN32 hosts, and the syscall
is missing from the gdb remote file i/o interface.
Since we can't implement it universally, drop it.

The UHI specification does not have an EFAULT value,
and further specifies that "undefined UHI operations
should not return control to the target".
So, log the error and abort.

- Refactoring for non-coroutine variants of bdrv/blk_co_* functions:
Auto-generate more of them with the block coroutine wrapper generator
script
- iotest fixes
- Both for the storage daemon and the system emulator: Fix PID file
handling when daemonizing (store the absolute path and delete that on
exit, which is necessary because daemonizing will change the working
directory to /)
