[PATCH 0/3] Implement IMAGE_FEATURES in a general way

[Chris Larson <kergoth@gmail.com>]

From: Chris Larson <chris_larson@mentor.com>

This is a second attempt at this, scrapping the class changes from the previous
request and redoing it in a less invasive way, and breaking up the changes into
3 pieces. This implements IMAGE_FEATURES. IMAGE_FEATURES is analagous to
DISTRO_FEATURES and MACHINE_FEATURES, for root filesystem construction.
Currently, the only supported features are any defined package groups, as used
by the oe.packagegroup python module.

Example usage:

    PACKAGE_GROUP_myfeature = "vim iptables"
    IMAGE_FEATURES += "myfeature"

This also makes the dev-pkgs and dbg-pkgs features general, and adds a doc-pkgs
feature.


The following changes since commit 866a34dd80228a0c10cbea5d7715e2acd6cea131:

  uclibc_0.9.32: Sync mount.h from eglibc (2011-08-09 15:17:45 +0100)

  image: add support for generally useful {dev,doc,dbg}-pkgs features
  core-image: adjust to use the new IMAGE_FEATURES support
