[yocto] [RFC] Yocto Bug 5044, 6149 PREFERRED_PROVIDER runtime

[Jate Sujjavanich]

This patch allows a PREFERRED_PROVIDER to be specified for a runtime
package. It's working for me on poky 1.6.3 (Daisy). I have tested it with
the sshd example in Yocto Bug #5044 (sshd) and #6149
(libasound-module-bluez).

# In my local.conf
IMAGE_INSTALL_append = " sshd"
PREFERRED_PROVIDER_sshd = "dropbear"

However, when I try it with a core-image-minimal on today's poky master, my
image build fails on in the package manager (with the approximate error
message):

sshd not found in base feeds

This has me thinking that something has changed in the rpm packager since
1.6, and on master the rpm packager should create a rpm dependency on
dropbear instead of sshd (per the PREFERRED_PROVIDER). I think that this
would have implications for the other package classes as well. Does this
sound right?
