Polkit systemd support is upstream
Clean up layer settings
Vim still needs a link for Nawk
Remove tftp-hpa recipe.

More recent versions are maintained in meta-openembedded.
Disable meta-efl layer.

We are not using recipes from this layer.
Get rid of ifupdown recipes.

These binaries are provided by init-ifupdown in meta/recipes-core.
Remove rfkill append.

Rfkill seems to build find without this patch.  Also, rfkill is
provided by busybox in the gumstix images.
Remove netcat recipe.

This recipe is provided by meta-openembedded/meta-networking.
Remove realpath.

Realpath is provided by coreutils.
Remove openrdate recipe.

This package is obsolete and the rdate command is furnished by
busybox in any case.
Remove pump package.

This package appears unused.
Remove gtk-tweak package.

This recipe is just adding a gtkrc file to set the default
theme to gtk-clearlooks.  For gumstix images, let's just use
the default XFCE theme.
Remove i2c-tools.

A more recent version is provided by meta-oe.
Remove debianutils package.

We don't need the sensible-* utilities.
Remove the base-files bbappend.

This populates an empty issue file which is less useful than
the nice message telling us what version of poky we're based on.
Until we customize the message, let's drop this override.
Remove psplash override.

This isn't working.  Remove this until the basic splash is working.
Remove fbgrab and read-edid as they are broken.

Both these package don't compile because of missing defines etc.
Updating the recipes also didn't help.
Remove update-rc.d append.

Update-rc.d is not getting run on these images.
Update systemd override to populate tmpfiles.d

The console-kit service requires a specific directory to be
available---we add this to the existing var-run.conf file
shipped in the systemd package.
Update gumstix images.

These recipes now use IMAGE_FEATURES and packagegroups where possible.
