Mark Wielaard de2ed97f33 Update name, license and contributor policy. 
* Change name from "Red Hat elfutils" to "elfutils".
* Update license of standalone tools and test from GPLv2 to GPLv3+.
* Change license of libraries from GPLv2+exception to GPLv2/LGPLv3+.
* Add Developer Certificate of Origin based contributor policy.

top-level:

- COPYING: Upgraded from GPLv2 to GPLv3.
- CONTRIBUTING, COPYING-GPLv2, COPYING-LGPLv3: New files.
- NEWS: Added note about new contribution and license policy.
- Makefile.am: Updated to GPLv3, added new files to EXTRA_DIST.
- configure.ac: Update to GPLv3, changed AC_INIT name to 'elfutils'.

backends, lib, libasm, libcpu, libdw, libdwfl, libebl, libelf:

- All files updated to GPLv2/LGPLv3+. Except some very small files
  (<5 lines) which didn't have any headers at all before, the linker
  .maps files and the libcpu/defs files which only contain data and
  libelf/elf.h which comes from glibc and is under LGPLv2+.

config:

- elfutils.spec.in: Add new License: headers and new %doc files.
- Update all license headers to GPLv2/LGPLv3+ for files used by libs.

src, tests:

- All files updated to GPLv3+. Except for the test bz2 data files, the
  linker maps and script files and some very small files (<5 lines)
  that don't have any headers.
