    This incorporates:
    2017-05-16 manywarnings: update for GCC 7
    2017-05-15 sys_select: Avoid "was expanded before it was required"
    * configure.ac (nw): Suppress GCC 7’s new -Wduplicated-branches and
    -Wformat-overflow=2 options, due to too many false alarms.
    * doc/misc/texinfo.tex, lib/strftime.c, m4/manywarnings.m4:
    Copy from gnulib.
    * m4/gnulib-comp.m4: Regenerate.
    * src/coding.c (decode_coding_iso_2022):
    Fix bug uncovered by -Wimplicit-fallthrough.
    * src/conf_post.h (FALLTHROUGH): New macro.
    Use it to mark all switch cases that fall through.
    * src/editfns.c (styled_format): Use !, not ~, on bool.
    * src/gtkutil.c (xg_check_special_colors):
    When using sprintf, don’t trust Gtk to output colors in [0, 1] range.
    (xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool;
    this bug was actually caught by Clang.
    * src/search.c (boyer_moore):
    Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character.
    * src/xterm.c (x_draw_glyphless_glyph_string_foreground):
    Tell GCC that glyph->u.glyphless.ch must be a character.
