The variable MULTILIB_PACKAGE_ARCHS has been removed in favor of a
repurposed MULTILIB_PREFIX_LIST. The format of this item is now
<libid>:<arch>:<arch1>:...:<archN>. This ensures that we can correctly
translate the libid to one of the supported archs in a tri-lib system.
All of the users of MULTILIB_PREFIX_LIST and MULTILIB_PACKAGE_ARCHS have
been modified accordingly.
Also change the way attempted packages are installed, verify the package
exists in the translate functions, then perform the install in one single
operation. This results in a significantly faster install time.

Use a similar mechanism that was previously used to install locales at
rootfs generation time to install other "complementary" packages (e.g.
*-dev packages) - i.e. install all of the explicitly requested packages
and their dependencies, then get a list of the packages that were
installed, and use that list to install the complementary packages. This
has been implemented by using a list of globs which should make it
easier to extend in future.
The previous locale package installation code assumed that the locale
packages did not have any dependencies that were not already installed;
now that we are installing non-locale packages this is no longer
correct. In practice only the rpm backend actually made use of this
assumption, so it needed to be changed to call into the existing package
backend code to do the complementary package installation rather than
calling rpm directly.
This fixes the doc-pkgs IMAGE_FEATURES feature to work correctly, and
also ensures that all dev/dbg packages get installed for
dev-pkgs/dbg-pkgs respectively even if the dependency chains between
those packages was not ensuring that already.
The code has also been adapted to work correctly with the new
SDK-from-image functionality. To that end, an SDKIMAGE_FEATURES variable
has been added to allow specifying what extra image features should go
into the SDK (extra, because by virtue of installing all of the packages
in the image into the target part of the SDK, we already include all of
IMAGE_FEATURES) with a default value of "dev-pkgs dbg-pkgs".
Fixes [YOCTO #2614].

INC_RPM_IMAGE_GEN = "1", the rpm based rootfs would be kept, and will do
update(remove/add some pkgs) on it.
NOTE: This is not suggested when you want to create a productive rootfs
For example:
1) Add the follow config option to a conf file:
INC_RPM_IMAGE_GEN = "1"
2) bitbake core-image-sato
modify a package
bitbake core-image-sato
The rootfs would not be totally removed and re-created in the second
generation, it would be simply updated based on the "package".
Implatation:
1) Figure out the pkg which need to be removed or re-installed, then use
'rpm -e to remove the old one. Use the rpm's BUILDTIME to determine
which pkg has been rebuilt.
2) Figure out the pkg which is newly added, and use 'rpm -U' to install
it.
This only for the rpm based rootfs, the deb and ipk based rootfs would
be done later.

Let each package-specific rootfs implementation provide basic functions
to query the existence of a package and install a list of packages and
then have a generic install function so this logic is in one place.
Note: unlike previous versions of this code in OE-Core this uses the
IMAGE_LINGUAS variable and not IMAGE_LOCALES - note that IMAGE_LINGUAS
was what was used in OE-Classic and it is already used in OE-Core in
order to install locale-base-*. This will mean that if IMAGE_LINGUAS is
left at the default you will now get more packages installed. If you
don't want these language support packages then you should set
IMAGE_LINGUAS explicitly.
This restores locale installation to the same state as OE-Classic, only
we now support all the packaging backends.

these scripts are run by a separate step at init time, but

can just be run when the package is installed on the target).
This patch lets the distribution (or user) decide when these

near the end of init, but there may be times when it's beneficial
