[equinox-dev] more changes in the metadata

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

I released a set of changes that involved
changing the shape of the metadata by removing the "group" objects.
 Explicit group objects are not replaced with IUs that have the "group"
capability.

Unfortunately, because of the way things
are serialized, this means you have to regen all the metadata you are using.
 Also, if you are setup for selfhosting, you will want to delete the

        <my
workspace>/.metadata/.plugins/org.eclipse.equinox.prov.selfhosting
dir and ensure that the selfhosting
host workspace has all the latest stuff.

Note that as part of these changes I
also put in a first cut of a "query" facility that allows you
to discover IUs with the capabilities you require.  Take a look at
the "provlg" command in the console for an example of how to
use this.
