localrepo: give a sigh of relief when getting lock after waiting for it

A message like this was sometimes shown when pushing:
  remote: waiting for lock on repository foo held by 'mercurial:20858'
That could scare users, making them wonder whether the push actually succeeded.

To mitigate that fear, issue an additional "warning" such as:
  got lock after 2 seconds

The return value from lock.lock.lock() was unused - instead we return the
delay.

This also adds the first test coverage for waiting for locks.

Prepare

  $ hg init a
  $ echo a > a/a
  $ hg -R a ci -A -m a

Pushing to a local read-only repo that can't be locked

  $ chmod 100 a/.hg/store

  $ hg -R b push a
