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
https://fedorahosted.org/freeipa/ticket/239
Constant values were assigned to variables gthat would later be freed
with slapi_ch_free_string(). Make copies instead so the free doesn't
blow. Also remove useless tests, as these functions already check for
NULL on their own.
Fixes: https://fedorahosted.org/freeipa/ticket/529
Consolidate the common logging macros into common/util.h and use them
in SLAPI plugins instead of calling slapi_log_error() directly.
