The default compression flag defined by automake via GZIP_ENV is --best.
That is pretty expensive for when you just want to make sure your change
is done properly to pass 'make distcheck'.
Hence add a convenience target 'make distcheck-fast' that sets GZIP_ENV
to --fast and runs distcheck with that.
On my machine, this almost cuts the 'make distcheck' time in half:
distcheck 4min 40s
distcheck-fast 2min 32s
This is not invasive as it does not change the existing distcheck
target.
* Makefile.am: add distcheck-fast make target

Symbols of pretty much all member functions of types that are meant to
be "private" to translation units that contribute to libabigail.so
were exported because we didn't do much to prevent that.
This patch starts controlling the set of symbols that are exported.
By default, symbols of any entity declared in a translation unit that
contributes to libabigail.so are hidden by default. Only symbols of
entities declared in public headers (headers in include/*.h) are
exported.
There are many ways to achieve that. This patch chooses to avoid
cluttering declarations of entities in the public header by adding
__attribute__((visibility="default")) to every declared type of
function in there.
Rather, the patch uses "#pragma GCC visibility push(default)" before
entities declared on those headers. By doing so, all those entities
have their symbol marked as "visible" by the compiler. Once the
header are #included, the #pragma GCC visibility pop" is used, so that
anything else has its symbol be hidden from that point on.
Note that for ease of maintenance the patch uses the macros
ABG_BEGIN_EXPORT_DECLARATIONS and ABG_END_EXPORT_DECLARATIONS rather
than using the pragma directive directly.
I believe this is a more elegant way of handling visibility, compared
to cluttering every single declaration in public headers with a
"__attribute__((visibility=("default")))" or with a macro which
expands to it.
This reduces the the set of symbols exported by libabigail.so from
20000+ to less than 5000.

* CONTRIBUTING: Update the "contributing guide" to refer to symbol

After I tried to build libabigail on Debian, I realized the detection
of python modules wasn't that great. The koji module wasn't present
and yet the detection system tried to launch fedabipkgdiff regression
tests. Woops.
I was thinking about coming up with something easier to to update to
add new modules to check for anyway, so I just dived in. I came up
with a new autoconf macro of my own, AX_CHECK_PYTHON_MODULES, that
lets you check for the presence of several python modules at once.
This is more handy than having to call AX_PYTHON_MODULE for each
module we want to detect. This fixes the detection issue I found and
simplifies configure.ac.
* configure.ac: Include
autoconf-archive/ax_check_python_modules.m4 rather than
autoconf-archive/ax_python_module.m4. Use AX_CHECK_PYTHON_MODULES
rather than AX_PYTHON_MODULE.

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.
