[Qemu-stable] [PATCH v2 0/2] docs/interop/bitmaps: rewrite and modernize doc

[John Snow]

The documentation as written in the 4.0 release is not quite correct as
of the 4.0 release; though thanks to backwards compatibility it's not
quite wrong either. It is suitable for inclusion in 4.0.1, or any
downstream that packages 4.0.

This patch is an attempt at a nearly full rewrite that revitalizes this
document to address frequent questions I encounter when discussing the
API.

V2:
  - Split off makefile change into its own little patch.

  - Addressed (almost) all comments from Vladimir.
    - Example styling was not reworked.
  - Renamed all filenames to be consistent throughout the document,
    fixing a few more file extensions in the process
  - Reflowed almost all paragraphs to 78 columns for consistency.
  - Changed a few bulleted lists to paragraphs instead
  - Changed the big ascii text diagram to a more compact version
    and clarified its language
  - While in general I prefer to use en_US spellings, I have
    replaced "canceled" with "cancelled" so it does not look
    out of place juxtaposed with BLOCK_JOB_CANCELLED...

Future work that remains to be done:

- Paying heed to blockdev-backup workflows
- Adding a small migration section explaining the options there
- Possibly reworking some of the sections that all make their own
  repeated attempts to clarify time interval discretization and adding
  a proper treatment of the idea start to finish; this may be neccessary
  to explain the two below items properly:
- Differential Backups
- Pull Backups and NBD
