py3: add warnings in check-code related to py3

We have our own bytes versions of things like, getopt.getopt, os.sep, os.name,
sys.executable, os.environ and few more for python 3 portability. Its better
to come up with warnings if someone breaks the things which we have fixed.

After this patch, check-code will warn us to use our bytes version.
These checks run on mercurial/ and hgext/ and pycompat.py is excluded.

#require test-repo

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ check_code="$TESTDIR"/../contrib/check-code.py
  $ cd "$TESTDIR"/..

New errors are not allowed. Warnings are strongly discouraged.
(The writing "no-che?k-code" is for not skipping this file when checking.)
