[Libguestfs] [PATCH v5 00/32] Refactor utilities, implement some APIs in OCaml.

[Richard W.M. Jones]

This is a combination of:

  https://www.redhat.com/archives/libguestfs/2017-June/msg00046.html
  [PATCH 00/12] Refactor utility functions.

plus:

  https://www.redhat.com/archives/libguestfs/2017-June/msg00023.html
  [PATCH v3 00/19] Allow APIs to be implemented in OCaml.

with the second patches rebased on top of the utility refactoring, and
some other adjustments and extensions.

This passes the basic tests.

Rich.
