Some parts of install scripts used only ccache name as returned by
krbV.CCache.name attribute. However, when this name is used again
to initialize krbV.CCache object or when it is used in KRB5CCNAME
environmental variable, it fails for new DIR type of CCACHE.
We should always use both CCACHE type and name when referring to
them to avoid these crashes. ldap2 backend was also updated to
accept directly krbV.CCache object which contains everything we need
to authenticate with ccache.

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
