[PATCH RESEND v2 00/32] hw: Sanitize various MemoryRegion calls

[Philippe Mathieu-Daudé]

Resending after being kicked by gsmtp...

 4.3.0 Temporary System Problem.  Try again later (10). t81sm863436wmg.6 - gsmtp

This series simplifies various memory API calls when creating
memory regions.

Most of the patches are generated with Coccinelle semantic
patches (provided).
Few more cleanups added while writting the patches have been
added.

v1 was 'Let devices own the MemoryRegion they create':

Since v1:
- understood a bit more Peter Maydell comments regarding
  how memory devices are migrated.

Supersedes: <address@hidden>
