hgweb: use sslutil.wrapserversocket()

This patch transitions the built-in HTTPS server to use sslutil for
creating the server socket.

As part of this transition, we implement developer-only config options
to control CA loading and whether to require client certificates. This
eliminates the need for the custom extension in test-https.t to define
these.

There is a slight change in behavior with regards to protocol
selection. Before, we would always use the TLS 1.0 constant to define
the protocol version. This would *only* use TLS 1.0. sslutil defaults
to TLS 1.0+. So this patch improves the security of `hg serve` out of
the box by allowing it to use TLS 1.1 and 1.2 (if available).

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
