Introduce meta-agl-profile-core and meta-agl-profile-graphics

Rework towards agl profiles.

This change is part of a series of changes to create the
AGL profiles.

This set will mainly introduce the 'core' profile.

It is setup to be a drop-in change, thus some files were kept
in (dummy) locations for now.
However, they'll be taken care of in the next changes in this series.

The main target of the meta-agl-profile-core layer is to host:
- a minimal, bootable image with network and package management enabled
  -- agl-image-boot
- a minimal image with network and packagemanagement and the AGL APIs
  -- agl-image-minimal

The layer meta-agl-profile-graphical is used as superset of these
and includes support for egl+wayland+weston. All recipes concerning
graphics were moved there. This is not a full profile as we still have
to migrate some parts of meta-agl-demo in a follow-up changeset.

The roadmap as discussed during the F2F session in Karlsruhe is:
- week 16 : core profile and profiles w/o graphics
- week 17 : graphical profiles
- week 18 : final conversion of the demo image

v2: moved agl-login-manager from -graphics to -core (see Jose's comment)
v3: moved back after discussion - follow-up in separate changeset

+Description: Lie about futex_atomic_cmpxchg_inatomic kernel support.
+ In past versions of glibc, we incorrectly assumed all ARM kernels
+ in all configurations supported futex_atomic_cmpxchg_inatomic. This
+ was clearly a lie, however it was a lie that we relied on, because
+ the fallback implementation appears to not play nicely with certain
+ applications like pulseaudio.  Restore the lie for kernels > 2.6.32
+ and plug our ears and scream "LA LA LA" about how wrong this is.
