  Fix some minor chan_dahdi config load issues.

  * Address chan_dahdi.conf dahdichan option todo item about needing line
  number.

  * Make ignore_failed_channels option also apply to dahdichan option.

  * Don't attempt to create a default pseudo channel if the chan_dahdi.conf
  channel/channels option is not allowed.

  * Add a similar check for dahdichan in normal chan_dahdi.conf sections as
  is done in users.conf.
