Starting work on the shibboleth-sp2 packages

[Scott Cantor]

Seems as good a time as any to note that I'm probably only a couple of weeks
out from shipping 2.1, which also includes .0.1 updates to xmltooling and
opensaml.

All the reported Debian issues should be fixed in this release and the
log4cpp build issue was worked around, though that seems to be a gcc bug
that isn't going away, not an error.

Regarding the WS-Trust schema, I'm not sure how it's materially different
from the W3C or OASIS schemas I include. I wouldn't even be surprised if
those copyrights were worse.
