url: always use str for proxy configuration

Previously, proxies didn't work on Python 3 for various reasons.

First, the keys to the "proxies" dict are fed into a
`setattr(self, "%s_open", ...)` call and passing bytestrings
results in setting an oddly named attribute due to the b''
in %s formatting. This resulted in "http_open" and "https_open"
not being properly overridden and proxies not being used.

Second, the standard library was expecting proxy URLs to be
str. And various operations (including our custom code in
url.py) would fail to account for the str/bytes mismatch.

This commit normalizes everything to str and adjusts our
proxy code in url.py to account for the presence of str
on Python 3.

Tests narrow stream clones

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

#if tree
  $ cat << EOF >> $HGRCPATH
  > [experimental]
  > treemanifest = 1
  > EOF
#endif

#if flat-nofncache
  $ cat << EOF >> $HGRCPATH
  > [format]
  > usefncache = 0
  > EOF
#endif

Server setup

  $ hg init master
  $ cd master
  $ mkdir dir
  $ mkdir dir/src
  $ cd dir/src
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "F$x"; hg add "F$x"; hg commit -m "Commit src $x"; done

  $ cd ..
  $ mkdir tests
  $ cd tests
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "F$x"; hg add "F$x"; hg commit -m "Commit src $x"; done
  $ cd ../../..

Trying to stream clone when the server does not support it

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream
  streaming all changes
  remote: abort: server does not support narrow stream clones
  abort: pull failed on remote
  [255]

Enable stream clone on the server

  $ echo "[experimental]" >> master/.hg/hgrc
  $ echo "server.stream-narrow-clones=True" >> master/.hg/hgrc

Cloning a specific file when stream clone is supported

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream
  streaming all changes
  * files to transfer, * KB of data (glob)
  transferred * KB in * seconds (* */sec) (glob)

  $ cd narrow
  $ ls
  $ hg tracked
  I path:dir/src/F10

Making sure we have the correct set of requirements

  $ cat .hg/requires
  dotencode (tree flat-fncache !)
  fncache (tree flat-fncache !)
  generaldelta
  narrowhg-experimental
  revlogv1
  sparserevlog
  store
  treemanifest (tree !)

Making sure store has the required files

  $ ls .hg/store/
  00changelog.i
  00manifest.i
  data (tree flat-fncache !)
  fncache (tree flat-fncache !)
  meta (tree !)
  narrowspec
  undo
  undo.backupfiles
  undo.narrowspec
  undo.phaseroots

Checking that repository has all the required data and not broken

  $ hg verify
  checking changesets
  checking manifests
  checking directory manifests (tree !)
  crosschecking files in changesets and manifests
  checking files
  checked 40 changesets with 1 changes to 1 files
