c80f79271a Re-license the project to Apache v2 With LLVM Exception 
Thanks to the previous work done, changing the license is just a
matter of changing the SPDX identifer from "LGPL-3.0-or-later" to
"Apache-2.0 WITH LLVM-exception".  Note that for the abigail.m4,
tests/test-dot.cc and tests/test-svg.cc the change was from
"GPL-3.0-or-later WITH GCC-exception-3.1" to "Apache-2.0 WITH
LLVM-exception".  include/abg-cxx-compat.h was changed from
"LGPL-2.0-or-later" to "Apache-2.0 WITH LLVM-exception".  Source code
of programs (as opposed to source code of the library) where generally
licensed under GPL-3.0-or-later; they are also now licensed
"Apache-2.0 WITH LLVM-exception".

This is what this patch does.

	* abigail.m4: Change the SPDX identifier from "GPL-3.0-or-later
	WITH GCC-exception-3.1" to "Apache-2.0 WITH LLVM-exception"
	* include/abg-cxx-compat.h: Change the SPDX identifier from

039ec5e478 Avoid comparing kernel.img file from the grub2 package 
The command "fedabipkgdiff --self-compare --from fc25 grub2" returns
with an error because no debug info can be found for the file
kernel.img.  That file doesn't have any debug info shipped for it.
And we shouldn't try to compare it anyway.

This patch updates the default suppression file shipped by libabigail
to make it avoid compare kernel.img files.

	* default.abignore: Do not compare kernel.img files.

6c6a8341dd Add default suppression specifications for C++ binaries 
For C++ libraries that are not libstdc++ or boost, this patch defines
default suppression specifications that drop function or variables that
we know are from namespaces that are not meant to be part of the API.
By doing so, we also decrease the memory needed to process the
binaries.

	non-boost C++ libraries.

67ca48da29 Add default suppression specification for webkitgtk 
This patch adds default suppression specifications for webkitgtk and
webkit2gtk so that unnecessary ABI artifacts are dropped from the
in-memory IR.  This dramatically helps to lower the memory usage of
libabigail while analyzing the webkit2gtk libraries.

1ab5aebf59 Bug 19967 - System-level suppressions for glibc 
This patch adds system-wide default suppression specifications for

b36ca1501e Bug 20180 - Support system-wide suppression specifications 
This patch adds support for loading system and user level suppression
specifications for libabigail tools.

At launch time, relevant libabigail tools (abidiff, abipkgdiff
fedabipkgdiff for now) read the default system suppression
specification file, if it's present, from a file which path is the
value of the environment variable
LIBABIGAIL_DEFAULT_SYSTEM_SUPPRESSION_FILE, if set, or from the file
$libdir/libabigail/default.abignore.

Then it reads the user system suppression specification file, if it's
present, from a file which path is the value of the environment
variable LIBABIGAIL_DEFAULT_USER_SUPPRESSION_FILE, if set, or from the
file $HOME/.abignore.

The content of the user system suppression file is merged with the
content of default system suppression file.

That content is also merged with the content of the suppression
specification files that might be provided by the --suppressions
command line option of the invoked tools.

The resulting set of all these suppression specifications is thus used
to filter the ABI change reports that are emitted.

abidiff, abipkgdiff and abipkgdiff gain a --no-default-suppression
option to avoid loading any of these default suppression specification
files.

The patch also installs a default.abignore file into $(pkglibdir).
Note that on x86_64, that directory is /usr/lib64/libabigail.  Now we
just need to think about the content of that default.abignore file.
