This patch implements the machine class kvm_type() callback.
It returns the number of bits requested to implement the whole GPA
range including the RAM and IO regions located beyond.
The returned value is passed though the KVM_CREATE_VM ioctl and
this allows KVM to set the stage2 tables dynamically.
To compute the highest GPA used in the memory map, kvm_type()
must freeze the memory map by calling virt_set_memmap().

Up to now the memory map has been static and the high IO region
base has always been 256GiB.
This patch modifies the virt_set_memmap() function, which freezes
the memory map, so that the high IO range base becomes floating,
located after the initial RAM and the device memory.
The function computes
- the base of the device memory,
- the size of the device memory,
- the high IO region base
- the highest GPA used in the memory map.
Entries of the high IO region are assigned a base address. The
device memory is initialized.
The highest GPA used in the memory map will be used at VM creation
to choose the requested IPA size.
Setting all the existing highmem IO regions beyond the RAM
allows to have a single contiguous RAM region (initial RAM and
possible hotpluggable device memory). That way we do not need
to do invasive changes in the EDK2 FW to support a dynamic
RAM base.
Still the user cannot request an initial RAM size greater than 255GB.

In the prospect to introduce an extended memory map supporting more
RAM, let's split the memory map array into two parts:
- the former a15memmap, renamed base_memmap, contains regions below
and including the RAM. MemMapEntries initialized in this array
have a static size and base address.
- extended_memmap, only initialized with entries located after the
RAM. MemMapEntries initialized in this array only get their size
initialized. Their base address is dynamically computed depending
on the the top of the RAM, with same alignment as their size.
Eventually base_memmap entries are copied into the extended_memmap
array. Using two separate arrays however clarifies which entries
are statically allocated and those which are dynamically allocated.
This new split will allow to grow the RAM size without changing the
description of the high IO entries.
We introduce a new virt_set_memmap() helper function which
"freezes" the memory map. We call it in machvirt_init as
memory attributes of the machine are not yet set when
virt_instance_init() gets called.
The memory map is unchanged (the top of the initial RAM still is
256GiB). Then come the high IO regions with same layout as before.

We generally put implicitly defined types in whatever module triggered
their definition. This is wrong for array types, as the included test
case demonstrates. Let's have a closer look at it.
Type 'Status' is defined sub-sub-module.json. Array type ['Status']
occurs in main module qapi-schema-test.json and in
include/sub-module.json. The main module's use is first, so the array
type gets put into the main module.
The generated C headers define StatusList in qapi-types.h. But
include/qapi-types-sub-module.h uses it without including
qapi-types.h. Oops.
To fix that, put the array type into its element type's module.
Now StatusList gets generated into qapi-types-sub-module.h, which all
its users include.

The #include directives to pull in sub-modules use file names relative
to the main module. Works only when all modules are in the same
directory, or the main module's output directory is in the compiler's
include path. Use relative file names instead.
The dummy variable we generate to avoid empty .o files has an invalid
name for sub-modules in other directories. Fix that.
Both messed up in commit 252dc3105f "qapi: Generate separate .h, .c
for each module". Escaped testing because tests/qapi-schema-test.json
doesn't cover sub-modules in other directories, only
tests/qapi-schema/include-relpath.json does, and we generate and
compile C code only for the former, not the latter. Fold the latter
into the former. This would have caught the mistakes fixed in this

- Remove check for s->tx != NULL, because it cannot happen.
- Cache ring->tail in a local variable and use it to check for
space in the TX ring. The use of nm_ring_empty() was invalid,
because nobody is updating ring->cur and ring->head at that point.
- In case we run out of netmap slots in the middle of a packet,
