The peripheral[-anon] containers are initialized lazily but since they sit on
sysbus, they can not be created after realize. This was causing an abort() to
occur during hotplug if no -device option was used.
This was spotted by qemu-test::device-add.sh

Push legacy properties into a "legacy-..." namespace, and make them
available with correct types too.
For now, all properties come in both variants. This need not be the
case for string properties. We will revisit this after -device is
changed to actually use the legacy properties.

This patch adds a visitor interface to Property. This way, QOM will be
able to expose Properties that access a fixed field in a struct without
exposing also the everything-is-a-string "feature" of qdev properties.
Whenever the printed representation in both QOM and qdev (which is
typically the case for device backends), parse/print code can be reused
via get_generic/set_generic. Dually, whenever multiple PropertyInfos
have the same representation in both the struct and the visitors the
code can be reused (for example among all of int32/uint32/hex32).

A NULL qobj can occur when a parameter is fetched via qdict_get, but
the parameter is not in the command. By returning NULL, the caller can
choose whether to raise a missing parameter error, an invalid parameter
type error, or use a default value. For example, qom-set could can
use this to reset a property to its default value, though at this time
it will fail with "Invalid parameter type". In any case, anything is
better than crashing!

With this patch, it only takes one test (instead of four)
to detect that there is no Xen support at all.
For most build hosts, this will reduce the time configure needs.
It will also reduce noisy output in config.log.
Build hosts with Xen now need up to five (instead of up to four)
tests. They get improved diagnostics when Xen support fails.
