procutil: rewrite popen() as a subprocess.Popen wrapper (issue4746) (API)

os.popen() of Python 3 is not the popen() we want. First, it doesn't accept
command in bytes. Second, a returned stream is always wrapped by TextIO.
So we have to reimplement our popen(). Fortunately, this fixes the bug 4746
since ours returns an exit code compatible with explainexit().

.. api::

   ``procutil.popen()`` no longer supports text mode I/O.

Test attempting a narrow clone against a server that doesn't support narrowhg.

  $ . "$TESTDIR/narrow-library.sh"

  $ hg init master
  $ cd master

  $ for x in `$TESTDIR/seq.py 10`; do
  >   echo $x > "f$x"
  >   hg add "f$x"
  >   hg commit -m "Add $x"
  > done

  $ hg serve -a localhost -p $HGPORT1 --config extensions.narrow=! -d \
  >    --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"
  $ hg serve -a localhost -p $HGPORT2 -d --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"

Verify that narrow is advertised in the bundle2 capabilities:
  $ echo hello | hg -R . serve --stdio | \
  >   $PYTHON -c "from __future__ import print_function; import sys, urllib; print(urllib.unquote_plus(list(sys.stdin)[1]))" | grep narrow
  narrow=v0

  $ cd ..

  $ hg clone --narrow --include f1 http://localhost:$HGPORT1/ narrowclone
  requesting all changes
  abort: server doesn't support narrow clones
  [255]

Make a narrow clone (via HGPORT2), then try to narrow and widen
into it (from HGPORT1) to prove that narrowing is fine and widening fails
gracefully:
  $ hg clone -r 0 --narrow --include f1 http://localhost:$HGPORT2/ narrowclone
