[0/9,final,act] Relicensing Libabigail to Apache 2.0 + LLVM Exception

  Hello,

With Libabigail 1.8 out of the door, it's now time to change the
license of the project to Apache 2.0 with the LLVM exception as I have
proposed and as the contributors have agreed to.

This patch set is intended to perform the license change.  After it is
applied, the license of the project will effectively be "Apache 2.0 +
LLVM Exception".

1.8 will thus be the last major version of Libabigail with the LGPLv3
license.  If need be, there can be minor version releases of 1.8 in
the future, with that same LGPLv3 license.  This will obviously be for
bug fixing only purposes.  And patches going into that 1.8 branch will
obviously need to have the LGPLv3 license.

Other than that, the next major release will be 2.0 and will have the
"Apache 2.0 + LLVM Exception" license.  By default, patches submitted
to the master branch are thus going to be under this new license.

As all the patches of the set have already been reviewed and
acknowledged by all the contributors, I went ahead and applied them to
the master branch.

Thank you all for your support through this non-trivial endeavour!
