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.
