In preparation for having some more common semihosting code let's
excise the current config magic from vl.c into its own file. We shall
later add more conditionals to the build configurations so we can

pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.
This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear. As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.

It was found that Hyper-V 2016 on KVM in some configurations (q35 machine +
piix4-usb-uhci) hangs on boot. Root-cause was that one of Hyper-V
level-triggered interrupt handler performs EOI before fixing the cause of
the interrupt. This results in IOAPIC keep re-raising the level-triggered
interrupt after EOI because irq-line remains asserted.
Gory details: https://www.spinics.net/lists/kvm/msg184484.html
(the whole thread).
Turns out we were dealing with similar issues before; in-kernel IOAPIC
implementation has commit 184564efae4d ("kvm: ioapic: conditionally delay
irq delivery duringeoi broadcast") which describes a very similar issue.
Steal the idea from the above mentioned commit for IOAPIC implementation in
QEMU. SUCCESSIVE_IRQ_MAX_COUNT, delay and the comment are borrowed as well.

collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1
This is due to a dependency in acpi-build.c on the ICH9_LPC
(via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices.
To allow better modularity (compile acpi-build.c with only
Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as
object_resolve_type_unambiguous(). This way we relax the
linker dependencies and can build the x86 targets with a
selection of machines (instead of all of them).

We currently use Qemu's default of 128MB. As we know how much ram each
machine ships with, make it easier on users by setting a default.
It can still be overridden with -m on the command line.

The ARM virt machines put firmware in flash memory. To configure it,
you use -drive if=pflash,unit=0,... and optionally -drive
if=pflash,unit=1,...
Why two -drive? This permits setting up one part of the flash memory
read-only, and the other part read/write. It also makes upgrading
firmware on the host easier. Below the hood, we get two separate
flash devices, because we were too lazy to improve our flash device
models to support sector protection.
The problem at hand is to do the same with -blockdev somehow, as one
more step towards deprecating -drive.
We recently solved this problem for x86 PC machines, in commit
ebc29e1bea. See the commit message for design rationale.
This commit solves it for ARM virt basically the same way: new machine
properties pflash0, pflash1 forward to the onboard flash devices'
properties. Requires creating the onboard devices in the
.instance_init() method virt_instance_init(). The existing code to
pick up drives defined with -drive if=pflash is replaced by code to
desugar into the machine properties.
There are a few behavioral differences, though:
* The flash devices are always present (x86: only present if
configured)
* Flash base addresses and sizes are fixed (x86: sizes depend on
images, mapped back to back below a fixed address)
* -bios configures contents of first pflash (x86: -bios configures ROM
contents)
* -bios is rejected when first pflash is also configured with -machine
pflash0=... (x86: bios is silently ignored then)
* -machine pflash1=... does not require -machine pflash0=... (x86: it
does).
The actual code is a bit simpler than for x86 mostly due to the first
two differences.
Before the patch, all the action is in create_flash(), called from the
machine's .init() method machvirt_init():
main()
machine_run_board_init()
machvirt_init()
create_flash()
create_one_flash() for flash[0]
create
configure
includes obeying -drive if=pflash,unit=0
realize
map
fall back to -bios
create_one_flash() for flash[1]
create
configure
includes obeying -drive if=pflash,unit=1
realize
map
update FDT
To make the machine properties work, we need to move device creation
to its .instance_init() method virt_instance_init().
Another complication is machvirt_init()'s computation of
@firmware_loaded: it predicts what create_flash() will do. Instead of
predicting what create_flash()'s replacement virt_firmware_init() will
do, I decided to have virt_firmware_init() return what it did.
Requires calling it a bit earlier.
Resulting call tree:
main()
current_machine = object_new()
...
virt_instance_init()
virt_flash_create()
virt_flash_create1() for flash[0]
create
configure: set defaults
become child of machine [NEW]
add machine prop pflash0 as alias for drive [NEW]
virt_flash_create1() for flash[1]
create
configure: set defaults
become child of machine [NEW]
add machine prop pflash1 as alias for drive [NEW]
for all machine props from the command line: machine_set_property()
...
property_set_alias() for machine props pflash0, pflash1
...
set_drive() for cfi.pflash01 prop drive
this is how -machine pflash0=... etc set
machine_run_board_init(current_machine);
virt_firmware_init()
pflash_cfi01_legacy_drive()
legacy -drive if=pflash,unit=0 and =1 [NEW]
