Paul Eggleton de3abcf78a combo-layer: allow splitting out local config

Allow splitting the local parts of the configuration (mostly
local_repo_dir and last_revision, although there is no limitation) to
a side-by-side -local.conf file, with component sections optionally
tagged with the combo layer branch name. This effectively allows you to:

 * avoid polluting the history by committing the updated last revision
   to the combo repository for every update
 * avoid putting local repo paths into the combo repository
 * manage multiple branches of the combo repository whilst avoiding the
   possibility of mixing the configuration for one branch with another.

An example split configuration (note, values may be artificial):

------------------- combo-layer.conf -------------------
[bitbake]
src_uri = git://git.openembedded.org/bitbake
dest_dir = bitbake
hook = scripts/combo-layer-hook-default.sh

[oe-core]
src_uri = git://git.openembedded.org/openembedded-core
dest_dir = .
hook = scripts/combo-layer-hook-default.sh
--------------------------------------------------------

---------------- combo-layer-local.conf ----------------
[bitbake]
local_repo_dir = ../repos/bitbake

[oe-core]
local_repo_dir = ../repos/oe-core

[bitbake|master]
branch = master
last_revision = db689a99beffea1a285cdfc74a58fe73f1666987

[oe-core|master]
branch = master
last_revision = 121a1499a81706366acc0081272a6bff634d4d62

[bitbake|denzil]
branch = 1.12
last_revision = 24b631acdaa143a4de39c6e1328849660c66f219

[oe-core|denzil]
branch = denzil
last_revision = 741146fa90f28f7ce8d82ee7f7e254872d519724
--------------------------------------------------------

It is assumed that the local config file will be added to .gitignore.

README

Poky

Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
