Merge with gnulib, pacifying GCC 7
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.
