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.

Differential Revision: https://phab.mercurial-scm.org/D5952

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.

  $ hg init source
  $ cd source
  $ touch foo
  $ hg add foo
  $ hg ci -m 'add foo'
  $ hg clone . ../corrupted
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo >> foo
  $ hg ci -m 'change foo'

Add a hook to wait 5 seconds and then abort the commit

  $ cd ../corrupted
  $ echo "[hooks]" >> .hg/hgrc
  $ echo 'pretxncommit = sh -c "sleep 5; exit 1"' >> .hg/hgrc

start a commit...

  $ touch bar
  $ hg add bar
  $ hg ci -m 'add bar' &

... and start a pull while the commit is still running

  $ sleep 1
  $ hg pull ../source 2>/dev/null
  pulling from ../source
  transaction abort!
  rollback completed
  abort: pretxncommit hook exited with status 1
