This updates gnulib to a relatively recent commit. Most of this was done by the gnulib import script; the only change I made was to update-gnulib.sh. Tested on x86-64 Fedora 34. I also did a mingw cross build.

"foo/bar.c" "bar.c"

not consider trailing slashes to be part of the component:

"foo/bar/" "bar"

"foo/bar//" "bar"
