More than 1k of TypeInfo instances are already marked as const. Mark the
remaining ones, too.

In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get VMStateDescription. The previous commit made
that unnecessary.
Include migration/vmstate.h only where it's still needed. Touching it
now recompiles only some 1600 objects.

The random number is intended for use by the guest. As such, we should
honor the -seed argument for reproducibility. Use the *_nofail routine
instead of rolling our own error handling locally.

Switch to using qcrypto_random_bytes() rather than rand() as
our source of randomness for the BCM2835 RNG.
If qcrypto_random_bytes() fails, we don't want to return the guest a
non-random value in case they're really using it for cryptographic
purposes, so the best we can do is a fatal error. This shouldn't
happen unless something's broken, though.
In theory we could implement this device's full FIFO and interrupt
semantics and then just stop filling the FIFO. That's a lot of work,
though, and doesn't really give a very nice diagnostic to the user
since the guest will just seem to hang.

Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.
This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.
Changes since v1:
* Prevented guest from writing [31..20] bits in rng_status
* Removed redundant minimum_version_id_old
* Added field entries for the state
* Changed realize function to reset
