Poky today has three different package managers, the well-known formats deb
and rpm is supported as well as ipkg that is good for embedded devices.

When building and having a good cache hit, a significant amount of time is
spent in the phase of generating a rootfs, which is really about the
performance of the package manager. ipkg is way slower than deb or rpm. To
save build time and also get a package manager that is suitanle for use on
targets where flash memory is a concern, support for apk is suggested.

However, it might or might not be what's wanted for Poky since it increases
the test matrix. Therefore this patch series refactors the package
management code so that it's possible to add more package managers in other
own layer. I will send another patch serie that will add apk.

Perfomance metrics below, (note that this includes build times).

OE-core today has three different package managers, the well-known formats deb
and rpm is supported as well as ipkg that is good for embedded devices.

When building and having a good cache hit, a significant amount of time is
spent in the phase of generating a rootfs, which is really about the
performance of the package manager. To save build time and also get a
package manager that is suitanle for use on targets where flash memory is a
concern, support for apk is suggested.

However, it might or might not be what's wanted for OE-core since it increases
the test matrix. Therefore I will refactor the package management code to
allow a layer to add a new package manager without editing the meta layer.

This refactor will be divided into multiple patch series to be easier to review,
this is the second patch series.
