This relicenses the libbtrfsutil library to LGPLv2.1+ from LGPLv3. People that have contributed non-trivial changes acknowledged the change and are listed below. There's a potential licensing conflict with the 'btrfs' utility that is GPLv2 and statically links libbtrfsutil, this is not a valid combination per the compatibility matrix as found in https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility or http://gplv3.fsf.org/dd3-faq . We also have an explicit request to change the license [1] (issue #323) from LGPLv3 to allow use in environments that don't like GPLv3. Though the library license is not GPLv3, the full text of the license is in the repository and the 'lesser' part is an addendum. This was perhaps a bit confusing, nevertheless this gets clarified as well.
