acpi: Permit OEM ID and OEM table ID fields to be changed

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table n

acpi: Permit OEM ID and OEM table ID fields to be changed

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.

Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).

This patch allows you to override these default values.

The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN

The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.

Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.

This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

Include hw/qdev-properties.h less

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

vmgenid: replace x-write-pointer-available hack

This compat property sole function is to prevent the device from being
instantiated. Instead of requiring an extra compat property, check if
fw_cfg has DMA enabled.

fw_cfg is a built-in device that is initialized very early by the
machine init code. We have at least one other device that also
assumes fw_cfg_find() can be safely used on realize: pvpanic.

This has the additional benefit of handling other cases properly, like:

$ qemu-system-x86_64 -device vmgenid -machine none
qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide
$ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.9 -global fw_cfg.dma_enabled=off
qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide
$ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.6 -global fw_cfg.dma_enabled=on

hw/acpi/vmgenid: prevent device realization on pre-2.5 machine types

The WRITE_POINTER linker/loader command that underlies VMGENID depends on
commit baf2d5bfbac0 ("fw-cfg: support writeable blobs", 2017-01-12), which
in turn depends on fw_cfg DMA.

DMA for fw_cfg is enabled in 2.5+ machine types only (see commit
e6915b5f3a87, "fw_cfg: unbreak migration compatibility for 2.4 and earlier
machines", 2016-02-18).

Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging

virtio, pc: fixes, features

virtio support for region caches broke a bunch of stuff - fixing most of
it though it's not ideal. Still pondering the right way to fix it.
New: VM gen ID and hotplug for PXB.

ACPI: Add Virtual Machine Generation ID support

This implements the VM Generation ID feature by passing a 128-bit
GUID to the guest via a fw_cfg blob.
Any time the GUID changes, an ACPI notify event is sent to the guest

The user interface is a simple device with one parameter:
- guid (string, must be "auto" or in UUID format
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
