Allow appending arbitrary text to the libabigail version string
representation. That is useful to identify custom versions of the
library (e.g. development versions or versions of a particular origin).
The feature can be enabled by passing VERSION_SUFFIX to `configure`,
e.g.
$ configure VERSION_SUFFIX="-dev"
That will extend the version string to (currently) 1.7.0-dev.
The behaviour before this patch remains the default behaviour of not
appending any additional text.
The feature stays intentionally undocumented as the main release of
libabigail will usually not carry a version suffix.
* configure.ac: add substitution for VERSION_SUFFIX
* include/abg-version.h.in: add define for ABIGAIL_VERSION_SUFFIX
* include/abg-config.h(abigail_get_library_version): add support
for a version suffix
* src/abg-config.cc(abigail_get_library_version): Likewise.
* src/abg-tools-utils.cc(get_library_version_string): Likewise.

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.
* configure.ac: Set the version revision to "rc0".
* doc/manuals/abicompat.rst: Adjust manual for new --version
option.
* doc/manuals/abidiff.rst: Likewise.
* doc/manuals/abidw.rst: Likewise.
* doc/manuals/abilint.rst: Likewise.
* doc/manuals/abipkgdiff.rst: Likewise.
* include/abg-config.h (config::{m_format_minor, m_format_major}):
Make these be strings.
(config::{get,set}_format_minor_version_number): Make these return
strings.
(config::{get,set}_format_major_version_number): Make these return
or take strings.
(abigail_get_library_version): Make this take strings.
* src/abg-config.cc (config::config): Adjust.
(config::{get,set}_format_major_version_number): Make these return
or take strings.
(config::{get,set}_format_minor_version_number): Make these return
strings.
(abigail_get_library_version): Make this take strings.
* include/abg-version.h.in: Make the version variables be strings.
* src/abg-writer.cc (write_translation_unit): The version numbers
are now strings so adjust.
* tools/{abicompat,abidiff,abidw,abilint,abipkgdiff,abisym}.cc
(options::display_version): New data member.
(options::options): Initialize it.
(display_usage): Add documentation for new --version option.
(parse_command_line): Parse new --version option.
(main): Support --version.
