abipkgdiff supports --dso-only to compare only ABI of shared libraries
instead of all binaries. So, with adding this option to fedabipkgdiff,
its user is also able to let fedabipkgdiff compare ABI of shared
libraries, or not.

This is to address the following enhancement requests:
#19588 - Add a --headers-dir1 and --headers-dir2 option to abidiff
#19948 - Add --devel-pkg1 and --devel-pkg2 options to abipkgdiff
When the user specifies where to find header files for two binaries
(or packages) being compared, this patch generates a type suppression
specification that filters out change reports about types that are
defined in files that are not in the set of header files specified.
The type suppression specification also suppresses change reports
about changed/added/removed virtual member functions which enclosing
class type matches the type suppression specification.
There is a corner case that the patch handles too, and that is
exhibited by the accompanying test case for abidiff. There can be a
class defined by DWARF as having no source location and as being a
pure declaration. This can be a class declaration that has inline
virtual members only, and one or several non-defined virtual methods
too. When that declaration is included in a source file, GCC
generates debug info that describes that class as being a
declaration-only class with no source declaration. This patch
considers such a class as being non defined; you know, like a true
opaque type. So it's considered being not defined in any public
header file. Changes to this kind of class are thus filtered out.

abidiff, abipkgdiff and abicompat now recognize a [suppress_file]
directive in suppression specifications. That directive instructs the
tool to avoid loading some binaries altogether.
This is the first directive that won't act on the result of the
comparison of two binaries. It actually acts earlier and prevents the
tool from loading some binaries altogether.
The directive looks like:
[suppress_file]
# Don't load any library named lib_private*.so
file_name_regexp = lib_private.*\\.so
This prevents the tool from loading (and thus comparing) any library
which name matches the pattern "lib_private*.so".
[suppress_file]
# Only load libraries name lib_public*.so
file_name_not_regexp = lib_public.*\\.so
This instructs the tool to only load (and compare) files which name
match the pattern "lib_public*.so".

The supression directives suppress_type, suppress_function and
suppress_variable support the two properties below, among others:
file_name_regexp = <some-regexp>
soname_regexp = <some-regexp>
When the regular expression matches either the file name or the
soname, then the suppression directive is activated.
This patch adds the support for these two additional properties for
these suppression directives:
file_name_not_regexp = <some-regexp>
soname_not_regexp = <some-regexp>
These activate the current suppression directive if the regular
expression does *NOT* match the file name or soname.
This is very helpful to express change report suppressions like:
"suppress all ABI change reports for all libraries but those with
file names (or sonames) with the pattern libfoobar.*"

In a suppression specification, soname_regexp or file_name_regexp
cannot be the only property of a suppression directive. For instance,
the suppression specification below won't work:
[suppress_type]
# suppress all change reports about *any type* from the library
# libtestfoo.so
file_name_regexp = libtestfoo.so
This is because as documented in the manual, the suppression directive
'suppress_type' requires that some other properties be specified. For
instance, the below would work:
[suppress_type]
name_regexp = .*
file_name_regexp
This was done on purpose to prevent folks from inadvertently
suppressing too much of change report bits.
But experience is showing that this is surprising some users. And in
hindsight, I kind of agree it's surprising.
So this patch allows the first example to work, as seems to be
expected.

This patch changed the revision number of the libabigail library to
make it reflect the fact that we are not in "release candidate" mode,
before the first 1.0 release. So the revision number is now "rc0".
The configuration manager has been updated to support version numbers
that are strings, so that it can supports things like "rc0".
Then, several libabigail tools have been modified to support the
--version option to display their version number.

Abipkgdiff now attempts to extract packages and compare the resulting
ELF pairs in parallel. First off, a thread is spawned to extract each
package and each debuginfo package. After the ELF files are extracted,
mapped and the threads are successfully collected, the resulting
ELF vectors are traversed to identify existing pairs and a list of
arguments for future comparison is made. This list is then sorted
by size from largest to smallest. Unless --no-parallel is
specified on the command line, MIN(pairs,active_processors) threads
are spawned, sharing a single list of arguments. This list is
processed and a map of (ELF_PATH,DIFF_CORPUS) is created. Meanwhile,
the main thread checks this same map for results in the original order
of the ELF pairs, ensuring sequential output. After all the diffing
and reporting is done, the threads are collected again.
* doc/manuals/abipkgdiff.rst: Mention the new --no-parallel option.
* tools/Makefile.am: Add -pthread to abipkgdiffs link options.
* tools/abipkgdiff.cc (elf_file_paths_tls_key): New key for the
thread-local vector of ELF filepaths.
(reports_map): A map of the path of the first ELF of a compared pair
and a corpus representing the difference.
(env_map): A map of the corpus difference and a corresponding
environment needed to be kept alive until the diff is reported.
({arg,map}_lock): mutexes to control access to the comparison argument
list and the {reports,env}_map respectively.
(options): Add a new member "parallel" and set it to true in the ctor.
(elf_file): Add a new "size" member and set it in the ctor.
(package descriptor): Arguments passed to extract_package_set.
(compare_args): Arguments passed to the ELF comparison function.
(display_usage): Mention the new "--no-parallel" option.
(pthread_routine_extract_package): A wrapper function around
extract_package to be used in a multi-threaded environment.
({first_second}_package_tree_walker_callback_fn): Add the new ELF file
paths to a thread-specific vector.
(compare): In an overload of compare, verbose output is updated to
always mention the ELF files being compared for each reported stage.
Reporting is no longer done in this function, the resulting difference
is instead passed back to the calling function for reporting in the
main thread, along with a corresponding environment.
(pthread_routine_compare): Accept a pointer to a vector of comparison
arguments. This function is to be called NTHREAD times and share the
vector passed to it with its other invocations. Create the environment
for compare() and store its output in a map if there is a difference.
(create_maps_of_package_content): Allocate memory for a thread local
vector of ELF paths and dispose of it before returning.
(pthread_routine_extract_pkg_and_map_its_content): Renamed from
extract_package_and_map_its_content. Extract the debuginfo as well as
the regular package in this function. Spawn a separate thread for the
extraction of the debug package.
(pthread_join): A function handling thread joining throughout package
extractions.
(prepare_packages): Spawn a thread to extract each set of packages.
(elf_size_is_greater): New comparison function used to order ELF pairs
by size.
(compare): In the overload of compare, pass through the ELF path
vectors and identify pairs to be diffed. Put them in a vector and sort
it by the summed ELF pair size. Spawn comparison threads and safely
check for results in the proper order of the ELF pairs. Report any
differences ASAP and collect the threads after all the reporting is
done, checking their return status.
(parse_command_line): Check for the "--no-parallel" option.

This patch adds support for properties source_location_not_in and
source_location_not_regexp in the [suppress_type] section of
suppression specifications. So the suppression specification:
[suppress_type]
source_location_not_in = foo1.h, foo2.h bar1.h bar2.h
suppresses ABI change reports about types that are *NOT* defined in
files foo{1,2}.h and bar{1,2}.h. The intended use of this construct is to
constrain abi change reports to types that are part of the API of a
given shared library. The API of the library is supposed to be
defined in foo.h and bar.h only.
Similarly, the suppression specification:
[suppress_type]
source_location_not_regexp = (foo|bar){1,2}\\.h
suppresses ABI change reports about types that are not defined in the
same set of files foo1.h, foo2.h, bar1.h and bar2.h.
