Create second ioapic, route virtio-mmio IRQs to it,
allow more virtio-mmio devices (24 instead of 8).
Needs ACPI, enabled by default, can be turned off
using -machine ioapic2=off

This will allow to increase the number of transports in
case we have enough irq lines available for them all.

Uses the existing gpex device which is also used as pcie host bridge on
arm/aarch64. For now only a 32bit mmio window and no ioport support.
It is disabled by default, use "-machine microvm,pcie=on" to enable.
ACPI support must be enabled too because the bus is declared in the
DSDT table.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

microvm is a machine type inspired by Firecracker and constructed
after its machine model.
It's a minimalist machine type without PCI nor ACPI support, designed
for short-lived guests. microvm also establishes a baseline for
benchmarking and optimizing both QEMU and guest operating systems,
since it is optimized for both boot time and footprint.
