IPA server/replica uninstallation may fail when it tries to restore
a Directory server configuration file in sysrestore directory, which
was already restored before.
The problem is in Directory Server uninstaller which uses and modifies
its own image of sysrestore directory state instead of using the
common uninstaller image.

The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think

If this ever gets out of sync the user can always remove
/var/lib/ipa-client/sysrestore/*, they just need to understand the
implications.
One potential problem is with certmonger. If you install the client
and then re-install without uninstalling then the subsequent
certificate request by certmonger will fail because it will already
be tracking a certificate in /etc/pki/nssdb of the same nickname and
subject (the old cert).
We have had a state file for quite some time that is used to return
the system to its pre-install state. We can use that to determine what
has been configured.
This patch:
- uses the state file to determine if dogtag was installed
- prevents someone from trying to re-install an installed server
- displays some output when uninstalling
- re-arranges the ipa_kpasswd installation so the state is properly saved
- removes pkiuser if it was added by the installer
- fetches and installs the CA on both masters and clients
