* include/abg-comp-filter.h (class harmful_filter): Update
comment.
(class redundant_filter): Declare new filter.
* include/abg-comparison.h (enum
diff_category::NOT_REDUNDANT_CATEGORY): New category. Update the
values of the other enumerators.
(diff_context::{add_diff, diff_has_been_traversed}): New overloads.
(diff_context::{categorizing_redundancy, show_redundant_changes}):
Declare new methods.
(diff_context::remove_from_category): Define new inline method.
* src/abg-comparison.cc (noop_deleter::operator()): Constify the
parameter.
(CATEGORIZE_REDUNDANCY_FROM_CHILD_NODE)
(UPDATE_REDUNDANCY_CATEGORIZATION_FROM_NODE_SUBTREE): New macros.
(TRAVERSE_DIFF_NODE_AND_PROPAGATE_CATEGORY)
(TRAVERSE_MEM_DIFF_NODE_AND_PROPAGATE_CATEGORY)
(TRAVERSE_MEM_FN_DIFF_NODE_AND_PROPAGATE_CATEGORY): Use the new
CATEGORIZE_REDUNDANCY_FROM_CHILD_NODE and
UPDATE_REDUNDANCY_CATEGORIZATION_FROM_NODE_SUBTREE macros above.
(ENSURE_DIFF_NODE_TRAVERSED_ONCE)
(ENSURE_MEM_DIFF_NODE_TRAVERSED_ONCE): If the (type_decl or class)
node hasn't been yet traversed, mark it as non-redundant.
(diff_context::priv::categorizing_redundancy): New member.
(diff_context::priv::priv): Initialize it.
(diff_context::{add_diff, diff_has_been_traversed): Define new
overloads.
(diff_context::mark_diff_as_traversed): Intern a diff node that is
marked as being traversed.
(diff_context::{categorizing_redundancy, show_redundant_changes}):
Define new methods.
(diff::is_filtered_out): A redundant function or top-level
variable is considered filtered-out. Otherwise, the new
NOT_REDUNDANT_CATEGORY doesn't play any role when comparing
allowed categories with the set of categories a diff node belongs
to.
(corpus::priv::categorize_redundant_changed_sub_nodes): Define
new member function.
(corpus_diff::priv::apply_filters_and_compute_diff_stats): Change
this to first walk the changed functions and variables to apply
filters, then categorize redundant changed functions, and then
walk the changed functions and variables again to count
filtered-out diff nodes.
(filtering::redundant_filter::visit): Define new member function.
* tools/bidiff.cc (options::show_redundant_changes): New data
member.
(options::options): Initialize it.
(display_usage): Add help string for the --redundant command line
option.
(parse_command_line): Add support for the --redundant command line
option.
