[v2,00/11] dump: Add arch section and s390x PV dump

Message

Previously this series was two separate series:
 * Arch section support
   Adds the possibility for arch code to add custom section data.

 * s390 PV dump support
   Adds PV dump data to the custom arch sections.

I've chosen to merge them so it's easier to understand why the arch
section support has been implement the way it is.

Additionally I've added a cleanup patch beforehand which cleans up the
GuestPhysBlock usage.

v2:
	* Added "dump: Cleanup memblock usage"
	* Fixed whitespace problems and review comments
	* Added missing *errp check in dump_end
