Add a possibility to do logging in init-xenstore-domain: use -v[...]
for selecting the log-level as in xl, log to stderr.

Instead of creating the xenstore-stubdom domain first and parsing the
kernel later do it the other way round. This enables to probe for the
domain type supported by the xenstore-stubdom and to support both, pv
and pvh type stubdoms.
Try to parse the stubdom image first for PV support, if this fails use
HVM. Then create the domain with the appropriate type selected.

Do you not want to check if highmem_end is larger than GB(4) before
putting in this region?

This hardcoded e820 map doesn't seem very flexible, but we
control the guest kernel anyway so I think this should be fine.
The rest of this patch looks okay to me.

Oh, just realized: further down I'm setting the guest's map with either
2 or 3 entries depending on dom->highmem_end value.
So I think this is fine.
