3ee685ad1c options: Complete the transition to numeric toggles (`#if') 
For the sake of review, this commit alters only the code; the affiliated
comments within the source files also need to be updated, but doing so
now would obscure the operational changes that have been made here.

* All on/off options have been switched to the numeric `#if' variant;
  that is the only way to make this `default_options.h.in' thing work
  in a reasonable manner.

* There is now some very minor compile-time checking of the user's
  choice of options.

* NO_FAST_EXPTMOD doesn't seem to be used, so it has been removed.

* ENABLE_USER_ALGO_LIST was supposed to be renamed DROPBEAR_USER_ALGO_LIST,
  and this commit completes that work.

* DROPBEAR_FUZZ seems to be a relatively new, as-yet undocumented option,
  which was added by the following commit:

    commit 6e0b539e9c
    Author: Matt Johnston <matt@ucc.asn.au>
    Date:   Tue May 23 22:29:21 2017 +0800

        split out checkpubkey_line() separately

  It has now been added to `sysoptions.h' and defined as `0' by default.

* The configuration option `DROPBEAR_PASSWORD_ENV' is no longer listed in
  `default_options.h.in'; it is no longer meant to be set by the user, and
  is instead left to be defined in `sysoptions.h' (where it was already being
  defined) as merely the name of the environment variable in question:

    DROPBEAR_PASSWORD

  To enable or disable use of that environment variable, the user must now
  toggle `DROPBEAR_USE_DROPBEAR_PASSWORD'.

* The sFTP support is now toggled by setting `DROPBEAR_SFTPSERVER', and the
  path of the sFTP server program is set independently through the usual
  SFTPSERVER_PATH.

1b69d6d658 Added OpenSSH-like -o command line option to dbclient. 
Like in OpenSSH, whitespaces are ignored, key and value may be separated
by one '=' character.

For now only yes/no flag parsing is implemented.

e815e97440 Try without identifying current user 
Small change that warns the user if the current user cannot be identified rather than aborting.  This came in handy when I put dropbear on a dlink that did not have a true user environment.  Falling back on the "-l" option and user@ options works just fine as a client.  The only implication I found is that the -J option will fail ungracefully without a known own_user.
