Here's a revised version of the http-auth / credential-helper series.

And here's something I've been meaning to do on top: actually echo
characters at the username prompt. We can't do this portably, but we can
at least stub out a compatibility layer and let each system do something
sensible.

  [1/6]: move git_getpass to its own source file
  [2/6]: refactor git_getpass into generic prompt function
  [3/6]: stub out getpass_echo function
  [4/6]: prompt: add PROMPT_ECHO flag
  [5/6]: credential: use git_prompt instead of git_getpass
  [6/6]: compat/getpass: add a /dev/tty implementation
