OE-Core Task Rework

Aims

See the following thread (cross-posted to OE/Yocto mailing lists): [1] [2] [3]

Existing tasks

Key:

# - enabled/disabled by appropriate MACHINE_FEATURES or DISTRO_FEATURES

% - substitutable using a variable in distro config (e.g. VIRTUAL_RUNTIME_*)

Note: recipe descriptions are extracted from the DESCRIPTION field in the recipe, and as you can see they need improvement.

task-base-extended	task-base task-base-wifi# task-base-bluetooth# task-base-3g#		Intended to add bluetooth/3g/wifi packages if it is possible to plug in an adapter for these into the machine (determined by availability of pci/usb/pcmcia etc.) Along with task-core-boot, this task is installed by default in any image that inherits from core-image.bbclass (unless the image sets its own value for IMAGE_INSTALL - e.g. core-image-minimal does this).

Missing tasks

Some ideas:

• Network management - add connman and plugins appropriate based on DISTRO_FEATURES / COMBINED_FEATURES. Should be overridable to networkmanager for those that prefer it with meta-oe.
• Full-featured command-line utilities - for when the ones provided by busybox aren't sufficient. This may satisfy the requirement for a non-LSB specific version of task-core-basic...?
• Web server - default to lighttpd, allow overriding to apache when a layer provides this
