Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

- miscellaneous cleanups for TCG (Emilio) and NBD (Bogdan)
- next part in the thread-safe address_space_* saga: atomic access
  to the bounce buffer and the map_clients list, from Fam
- optional support for linking with tcmalloc, also from Fam
- reapplying Peter Crosthwaite's "Respect as_translate_internal
  length clamp" after fixing the SPARC fallout.
- build system fix from Wei Liu
- small acpi-build and ioport cleanup by myself
