Richard Purdie 9f374c4e85 bitbake: providers: Add PREFERRED_RPROVIDER support
Sometimes you can end up in a situation where you need to specify that
a specific runtime entity should be provided by a specific entry.

An example of this is bluez where you could end up in a situation where
for example:

NOTE: multiple providers are available for runtime libasound-module-bluez (bluez4, bluez5)
NOTE: consider defining a PREFERRED_PROVIDER entry to match libasound-module-bluez
NOTE: multiple providers are available for runtime bluez-hcidump (bluez-hcidump, bluez5)
NOTE: consider defining a PREFERRED_PROVIDER entry to match bluez-hcidump

The only option here is to set something like PREFERRED_PROVIDER_bluez4 = "bluez4"
which is clearly not very informative.

I've actually held off adding RPROVIDER support for a long while as this
does have sigificant potential for misuse. It doesn't for example allow
multiple runtime providers of the same name to coexist, that simply isn't
supported. It therefore doesn't replace some of the name mappings such
as busybox verses coreutils that OE-Core faces as that is a different
problem with different constraints. This mechanism is simply to provide
bitbake with a hint to decide what the dependency tree should look like.

Also, this allows us to stop printing a confusing message telling the user
to set PREFERRED_PROVIDER when the setting needed would be rather ambiguous.

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 = "nodistro") and contains only emulated machine support.

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

Where to Send Patches
=====================

As Poky is an integration repository (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:

bitbake:
    Git repository: http://git.openembedded.org/bitbake/
    Mailing list: bitbake-devel@lists.openembedded.org

documentation:
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
    Mailing list: yocto@yoctoproject.org

meta-poky, meta-yocto-bsp:
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
    Mailing list: poky@yoctoproject.org

Everything else should be sent to the OpenEmbedded Core mailing list.  If in
doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.

    Git repository: http://git.openembedded.org/openembedded-core/
    Mailing list: openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix of
oe-core and poky-specific files.
