The .odp section is found by name. But ppc64_init used the e_shstrndx
Ehdr field for that. This is wrong if the file contains more than
SHN_LORESERVE sections. Use elf_getshdrstrndx instead to find the
shstrtab section.

This adds a minimal fallback unwinder for ppc64[le] in case we cannot find
CFI for a particular address. It simply always sets the program counter to
the link register, picks the previous stack pointer from the backchain,
and the previous link register from the LR save area.
This is enough for some simple situations when we don't have CFI and
seems to work nicely in the case of perf with libdw powerpc support:

ppc64 and ppc64le ELF files can also contain a power specific
.gnu.attributes section. Add support for those and recognize the new
GNU_Power_ABI_FP Single-precision hard float value.

Since elf_strptr can fail and return NULL we should always check the result
before usage. Debug sections are only handled by section name, so make sure
the name actually exists.

The big endian vs little endian changes are already handled by detecting
the EI_DATA data encoding. And the function descriptors are already not
used when we see there is no .opd section. This change adds new checks
for st_other bits, new relocations and recognizes DT_PPC64_OPT.

To distinguish between the current PPC64 ELF ABI and the revised
ELFv2 ABI that will not use function descriptors binutils started
to emit the version (currently 1) in the ehdr e_flags. Recognize
all valid versions (0, 1 or 2) in elflint by adding the hook
ppc64_machine_flag_check.

Some arches like ppc64 use function descriptor values instead of function
addresses causing matching of names and addresses to fail when using
dwfl_module_getsym or dwfl_module_addrsym.
Add ebl hook to resolve any function descriptor values found in non-ET_REL
modules.
The new function dwfl_module_getsym_info doesn't adjust the symbol value
in any way, but returns the adjusted and/or resolved address associated
with the symbol separately. The new function dwfl_module_addrinfo resolves
against both the address associated with the symbol (which could be the
function entry address) value and the adjusted st_value. So that it is
easy to resolve and match either function descriptors and/or function
entry addresses.
Since these new functions also return more information they replace the
dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never
made it into a released elfutils version.
addr2line and readelf now use the new functions when looking up functions
names. addr2line will now also display the section the address was found
in when given -x.
Extra testcases were added for both addr2line and the dwflsyms testscase.

* 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.
