Hi,

This is my take at salvaging some NEMU good work.
Samuel worked in adding the fw_cfg device to the x86-virt NEMU machine.
This series is inspired by NEMU's commit 3cb92d080835 [0] and adapted
to upstream style. The result makes the upstream codebase more
modularizable.
There are very little logical changes, this is mostly a cleanup
refactor.

Since v3 [3]:
- Addressed Christophe suggestion (patch #8)
- Rebased patch #15 since Eduardo merged Like Xu's work between.

Since v2 [2]:
- Addressed MST comments from v2 (only patch #2 modified)
  - do not use unsigned for enum
  - do not add unuseful documentation

Since v1 [1]:
- Addressed Li and MST comments

$ git backport-diff -u v3
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
