improve error message for failed fetch (fix #8702): print where to file issues (URL if possible)
Stop installing two unneeded files, including perf suite

Perf suite contains many files with dubious licensing and is
typically not useful in normal use. Since ed38447 it's no longer
needed to run tests.
Add docdir, mandir and man1dir environment variables for make install

Also change the default path for documentation to something more standard.
Copy doc/ and examples/ under $(build_docdir) instead of creating symlinks
as before, so that we don't need to remove unwanted files afterwards.
Finally, fix code relying on old paths.
Fix so `@edit` works on windows with the default editor + line number is
printed to the user when it is not passed to the editor.
