[OE-core] [PATCH 00/10] #10618: Increase oe-selftest coverage of wic codebase (first part)

[Ed Bartosh]

Hi,

The main goal of these changes was to increase test coverage by testing rawcopy plugin,
which was not covered by the wic test suite. While working on it I found and fixed
quite nasty bug in sparse_copy API and made set of other important changes to make
the test case working.

I've also removed rootfs_pcbios_ext plugin, which was broken for a long time and
cleaned up wic test suite to keep it in a good shape.

The goal set in bugzilla issue #10618 is to increase test coverage to at least 80%.
Now it's only 74%, so more changes will have to be made. This patchset is just a
first part of the work in this area.

Note for project maintainers:
This patchset is based on Maciej's "enhancements for non-x86 MACHINE support & fixed-size tests"
patchset: http://lists.openembedded.org/pipermail/openembedded-core/2017-March/134410.html so,
please merge it in the right order.

The following changes since commit e07ca8bd2bd4a8fa1fb9a0f3a8d9ff9a8f9c46c8:
