* 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.
