Drop suppressed ABI artifacts from the IR
This patch allows dropping suppressed ABI artifacts from the in-memory
internal representation right during the DWARF or abixml reading.
In practise, this means that abidw and abilint now have a
--suppressions options to give them suppression specifications. If a
suppression specification that has the "drop" property matches an ABI
artifact (type, function or variable) then that artifact is dropped
from the internal representation. This also applies to abidiff.
Note that now, by default, ABI artifacts (types) that are suppressed
due to the --headers-dir{1,2} option of abidiff are now also dropped
from the IR as well. Incidentally, abidw and abilint tools now have a
--header-dir option too.

Make abi{pkg}diff filter out changes about private types
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.
* include/abg-comp-filter.h: Update copyright year.

anymore. Otherwise, using a vector here make things too slow.
(type_suppression::suppresses_type): Likewise. Also, If the type
we are looking at has no location because it's a true opaque type

Implement a [suppress_file] suppression directive
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".
* doc/manuals/libabigail-concepts.rst: Document the new
'suppress_file' directive.
* include/abg-suppression.h (file_suppression): Define new class.

* tools/abidiff.cc (main): If a suppression specification
suppresses one of the input files, then do not perform the
comparison.
* tools/abipkgdiff.cc (compare): If a suppression specification
suppresses a file that is to be compared, then do not perform the

parameter. Do not create a diff context here anymore, do not load
suppression files here either.
(main): Use the new create_diff_context to create a diff context
and initialize it, including loading suppression specifications.
If any suppression specification suppresses a file to load, then
do not load perform any compatibility checking. Adjust
invocations of perform_compat_check_in_weak_mode and
perform_compat_check_in_normal_mode to pass the diff context.

Split suppression engine off of abg-comparison.{cc,h}
Until now, the suppression engine was part of the comparison engine.
The code of both was in the abg-comparison.{cc,h} files.
For the sake of greater modularity, this patch separates the suppression
engine from the comparison engine. The suppression engine now lives
in include/abg-suppression.h and src/abg-suppression.cc. The patch
also updates logical consumers of the suppression engine to adapt them
to the change.
* include/Makefile.am: Add abg-suppression.h to source
distribution.
* include/abg-comparison.h: Remove abg-ini.h include directive.
(suppression_sptr, suppressions_type): Move these typedefs to
abg-fwd.h.

(type_suppression::insertion_range::integer_boundary)

these forward declaration and typedefs to the new

suppr::suppressions_type&.

(is_child_node_of_base_diff): Declare these new functions. They
were previously static, local to abg-comparison.cc only. Now they
need to be exported because they are used by the suppression
engine's code that now lives in its one files.
* include/abg-fwd.h (suppr::{suppression_base, suppression_sptr,
suppressions_type}): Forward declare these here.
* include/abg-suppression.h (class suppression_base)
(type_suppression, type_suppression::insertion_range)
(type_suppression::insertion_range::boundary)
(type_suppression::insertion_range::integer_boundary)
(type_suppression::insertion_range::fn_call_expr_boundary)
(function_suppression, function_suppression::parameter_spec)
(variable_suppression): Move these type definitions here, in the
namespace suppr.
(read_suppressions, is_type_suppression, is_integer_boundary)
(is_fn_call_expr_boundary, is_function_suppression)
(is_variable_suppression, operator&)
(operator|): Move these function decalration here, in the
namespace suppr.
(type_suppression_sptr, type_suppressions_type)
(function_suppression_sptr, function_suppressions_type)
(variable_suppression_sptr, variable_suppressions_type): Move
these typedefs here, in the namespace suppr.
* src/Makefile.am: add src/abg-suppression.cc to source
distribution.
* src/abg-comparison.cc (is_type_diff, is_decl_diff, is_var_diff)
(is_function_decl_diff, is_pointer_diff, is_reference_diff)
(is_reference_or_pointer_diff, is_fn_parm_diff, is_base_diff)
(is_child_node_of_function_parm_diff, is_child_node_of_base_diff):
Export these functions.
(*suppression*): Move all the suppression-related definitions to
the new abg-suppression.cc.
* src/abg-suppression.cc: New file. Contains all the *suppression*
definitions from src/abg-comparison.cc, that are put in the suppr
namespace.
* tools/abicompat.cc: Adjust.
* tools/abidiff.cc: Likewise.
* tools/abipkgdiff.cc: Likewise.
