    Add debugedit-classify-ar and use it before running do_ar_file

    do_ar_file in find-debuginfo can be somewhat slow extracting archive
    members and adding them to a new ar file after debugedit processing.

    debugedit-classify-ar is a new helper that checks if an ar file has to
    be processed, so no unnecessary work is done. It checks that the given
    file is a regular archive containing ELF members that have .debug
    sections and that no errors occur while reading the archive and
    members. It can also check that there is a maximum number of members.

    Use this in debuginfo with a limit of 768 members.

    Add new tests/debugedit-classify-ar.at testcases.

             * tools/debugedit-classify-ar.c: New file.
             * scripts/find-debuginfo.in (do_file): Use
             debugedit-classify-ar before invoking do_ar_file.
             * Makefile.am (bin_PROGRAMS): Add debugedit-classify-ar.
             (debugedit_classify_ar_{SOURCES,CFLAGS,LDADD}): New variables.
             (dist_man_MANS): Add debugedit-classify-ar.1.
             (debugedit-classify-ar.1): New target.
             * .gitignore: Add debugedit-classify-ar[.1].
             * tests/debugedit-classify-ar.at: New tests.
             * tests/Makefile.am (TESTSUITE_AT): Add
             debugedit-classify-ar.at.
             * tests/testsuite.at: m4_include debugedit-classify-ar.at.
