UPDATE: (os, library, function) database

[Bruno Haible]

Hi all,

In 2007 I made available the (os, library, function) database that is the
basis for part of the gnulib documentation. [1]

Here comes an update, with many more recent OS versions included.
  https://www.haible.de/bruno/gnu/various-symlists.tar.gz

The point of this database is also to avoid mistaken assumptions about
portability, like I did in [2] regarding macOS. Example use:
