Allow ECF to build against both R6 and R7 implementations of the 
org.osgi.service.log API. This is accomplished by providing stubs of the
new interfaces on the build-time classpath so that we can implement the
new R7 methods without having unresolved classes on R6.
The stubs are not shipped with the binary distribution of ECF, so in the
actual ECF code we can use them as long as we avoid any explicit import
statements to avoid runtime linkage errors on R6.

Backport console bundle metadata changes from osgir7 branch
Allow building/running against Oxygen or Photon by keeping the 
require-bundle, but making it optional, so it may be fulfilled by either
the old-style felix-gogo bundle from Oxygen or any bundle that supplies
the felix.service.command package like the new-style felix-gogo bundle
from Photon.
