This is the second version of my patch series to improve DISTRO_FEATURES
& MACHINE_FEATURES handling. The first version complicated modification
of variables in conf files, requiring use of :append when we should just
be able to use +=.
In this version we directly append the filtered defaults to the target
variable, instead of using an intermediate variable. So, default distro
features are listed in DISTRO_FEATURES_DEFAULTS, this list is filtered
to remove features listed in DISTRO_FEATURES_OPTED_OUT and the result is
appended to DISTRO_FEATURES. Similar behaviour exists for
MACHINE_FEATURES_DEFAULTS, MACHINE_FEATURES_OPTED_OUT and
MACHINE_FEATURES.
See patches 2/4 & 3/4 for updated migration notes.
This series doesn't include issuing warnings if DISTRO_FEATURES_BACKFILL
or DISTRO_FEATURES_BACKFILL_CONSIDERED is set, that can be added as a
follow up if these changes are accepted.

Changes in v2:
- Rename {DISTRO,MACHINE}_FEATURES_DEFAULT_RAW to
{DISTRO,MACHINE}_FEATURES_DEFAULTS.
- {DISTRO,MACHINE}_FEATURES_DEFAULT is removed.
- filter_default_features() appends directly to
{DISTRO,MACHINE}_FEATURES.
- Follow through the consequences of the above changes.
- Changed in meta-yocto should no longer be needed.
