Neal Gompa 9e30f779e3 libbtrfsutil: relicense to LGPLv2.1+
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.
