Bug 18754 - Add the "--no-added-syms" option to abidiff

Browse Source 
With this option, abidiff is now able to filter out added
symbols just like abipkgdiff is.

	* doc/manuals/abidiff.rst: Document the new --no-added-syms
	option.
        * tools/abidiff.cc (struct options): Add show_added_syms and
        set it to true by default.
        (display_usage): Document the new options --no-added-syms. If
        this is the only suppression option specified, it is equivalent
        to specifying --show_{changed,deleted}_{fns,vars} as arguments
        to abidiff. If any of those options are specified before
        --no-added-syms, then it has no effect.
        (parse_command_line): Parse the new option and set
	show_added_{fns,vars,syms} and show_all_{fns,vars} to false if
	--no-added-syms is specified.
        * tests/test-diff-filter.cc: Add a test for the new option.
        * tests/data/test-diff-filter/test35-pr18754-no-added-syms-report-0.txt:
        Reference results for the new test.
        * tests/data/test-diff-filter/test35-pr18754-no-added-syms-report-1.txt:
        Likewise.
        * tests/data/Makefile.am: Add the above test files to the list of
        test data.
