types, not just builtin.  on win32 for example, a pipe dialog might
allocate a wintty for prompting, which results in 4 prompts at
startup, 2 for each child and 2 within each when httpd "restarts
itself".
update comments on this and wrap them a bit.

- return value from apr_dir_read() was checking != APR_SUCCESS rather
  than == APR_SUCCESS, so no certs were ever loaded.

- wasn't checking return value of apr_dir_open(), now log an error and
  ssl_die() on failure.

- don't bother trying to load directories

  Introduce PassPhraseDialog 'pipe' mechanism.  This builds on DougM's
  apr-ization of the 'tty', and changes his naming a bit so we clearly
  identify the pipe-to and pipe-from the user.

  This patch invokes a bidirectional piped dialog to the user.

  Introduce the PassPhraseDialog 'pipe' mechanism.

  This is the directive handling commit only, the mechanics patch will
  follow.  PassPhraseDialog "|/path/to/pipe" will use the bidirectional
  pipe to have a 'conversation', along the lines of the tty dialog with
  PassPhraseDialog 'builtin'.  This is entirely different than the 'exec'
  method, which simply runs once for each passphrase, and doesn't allow
  for failure/retries, and certainly doesn't offer any sensible 'dialog'.

and switch to using apr_file api for portability.
stderr has already been redirected to the error_log.
rather than attempting to temporarily rehook it to the terminal,
we print the prompt to stdout before EVP_read_pw_string turns
off tty echo.  which is also more portable.

than hack to only read passphrase on 1st round startup.  this change:
- fixes current segv on restarts (SHARED_MODULE is not defined)
- allows LoadModule ssl_module to be added to httpd.conf on restart
  (was core dumping previously)
- allows certs/keys to be changed on restart provided key is not
  encrypted or SSLPassPhraseDialog is exec.  if key is encrypted and
  SSLPassPhraseDialog is builtin, existing private keys will be reused
  on restart (which happens currently for any type of key/dialog).

note: mod_ssl currently leaks on restart; leaks more with this change.
      fixes to come.
