This calls the MACHINE_VER_DELETION() macro in the machine type
registration method, so that when a versioned machine type reaches
the end of its life, it is no longer registered with QOM and thus
cannot be used.
The actual definition of the machine type should be deleted at
this point, but experience shows that can easily be forgotten.
By skipping registration the manual code deletion task can be
done at any later date.

This calls the MACHINE_VER_DEPRECATION() macro in the definition of
all machine type classes which support versioning. This ensures
that they will automatically get deprecation info set when they
reach the appropriate point in their lifecycle.

This changes the DEFINE_VIRT_MACHINE macro to use the common
helpers for constructing versioned symbol names and strings,
bringing greater consistency across targets.
A DEFINE_VIRT_MACHINE_AS_LATEST helper is added so that it
is not required to pass 'false' for every single historical
machine type.

Rather than poking directly into RAM, add the bootinfo block as a proper
ROM, so that it's restored when rebooting the system. This way, if the
guest corrupts any of the bootinfo items, but then tries to reboot,
it'll still be restored back to normal as expected.
Then, since the RNG seed needs to be fresh on each boot, regenerate the
RNG seed in the ROM when reseting the CPU.

Following a change on the kernel side (see link), pass BI_RNG_SEED
instead of BI_VIRT_RNG_SEED. This should have no impact on
compatibility, as there will simply be no effect if it's an old kernel,
which is how things have always been. We then use this as an opportunity
to add this to q800, since now we can, which is a nice improvement.

Add a new property "big-endian" to allow configuring the RTC as either
little or big endian, the default is little endian.
Currently overriding the default to big endian is only used by the m68k
virt platform. New platforms should prefer to use little endian and not
set this.

This commit wires up bootinfo's RNG seed attribute so that Linux VMs can
have their RNG seeded from the earliest possible time in boot, just like
the "rng-seed" device tree property on those platforms. The link
contains the corresponding Linux patch.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).
