This series of patches splits wic out from oe-core into its own
standalone utility. The wic utility will continue to be under The Yocto
Project umbrella, but will no longer be integrated into the project
as part of oe-core. The ultimate goal is to make wic a completely
independent tool, hosted on PyPI, with its own tests, development
roadmap, and releases.

Some benefits include:
- relieving the oe-core maintainers from having to review wic patches
- allow the tool to be used outside of The Yocto Project
- provide more flexibility to explore other features, libraries,
  mechanisms, etc 

These changes have been tested with oe-selftest as follows:
        $ sudo .../layers/openembedded-core/scripts/runqemu-gen-tapdevs <my numeric group id> 4
        $ oe-selftest -v -r wic 

At this time, I have two separate patch sets for wic on oe-core: one
to create a standalone utility, and one to re-implement variable
sector-size handling. So far 3 versions have gone out for the standalone
set, and 4 have been posted for re-implementing variable sector-size
handling. With this patch set I have combined both efforts and marked
this as "v5". This is why some of the patches will point out there is
a missing version. It was decided that it would be better to
re-implement the variable sector-size handling before splitting wic out
since this has a big effect on the patches required to keep the
oe-selftests working.

For the standalone patch set:
v1: an RFC patchset was sent out, split up into small patches for easy
    review
v2: add wic utility to list of native dependencies of
    image_types_wic.bbclass
v3: squash all commits together to apply atomically
v4: (does not exist)
v5: rebase on latest master
    split commits back out acknowledging any bisection that lands
    between them will fail
    combine with sector-size patch

For the sector-size patch:
v1: initial patch set
v2: add Mark as co-author of ufs class
    try to fix a build warning when not using wic
v3: actually fix warning when not using wic
v4: deprecate, but allow, WIC_SECTOR_SIZE to continue to be used to set
    the sector-size both from config files and the environment
    warn when both are used, but prefer cmdline value
    change partition type of sample wks to gpt
v5: fix a bug where WIC_SECTOR_SIZE is not given anywhere
    combine with standalone patch set
