Mostly restore command-line parity

Restore most everything and remove the added server arguments.  This
will let us add and remove options after later so we can contain the
number of breaking changes.

To accomplish this a hard separation is added between the CLI arguments
and the server arguments.

The separation between user-provided arguments and arguments with
defaults is also made more clear.

The extra directory flags have been left out as they were buggy and
should be implemented upstream although I think there are better
solutions anyway.  locale and install-source are unsupported with the
web remote and are left removed.  It is unclear whether they were used
before anyway.

Some restored flags still need to have their behavior re-implemented.
