pycompat: export queue module instead of symbols in module (API)

Previously, pycompat and util re-exported individual symbols from the
queue module. This had the side-effect of forcing the loading of the
queue module whenever pycompat/util was imported.

These symbols aren't used very often. So importing the module to
get a handle on the symbols is wasteful.

This commit changes pycompat so it no longer exports the individual
symbols in the queue module. Instead, we make the imported module
a "public" symbol. We drop the individual symbol aliases from the
util module. All consumers are updated to use pycompat.queue.* instead.

This change makes 300 invocations of `hg log -r. -T '{rev}\n'` a little
faster:

before: 18.44s
after:  17.87s

Test temp file used with an editor has the expected suffix.

  $ hg init

Create an editor that writes its arguments to stdout and set it to $HGEDITOR.

  $ cat > editor.sh << EOF
  > echo "\$@"
  > exit 1
  > EOF
  $ hg add editor.sh
  $ HGEDITOR="sh $TESTTMP/editor.sh"
  $ export HGEDITOR

Verify that the path for a commit editor has the expected suffix.

  $ hg commit
  *.commit.hg.txt (glob)
  abort: edit failed: sh exited with status 1

Verify that the path for a histedit editor has the expected suffix.

  $ cat >> $HGRCPATH <<EOF

  $ hg commit --message 'At least one commit for histedit.'
  $ hg histedit
