dont-save-plaintext-passwords-by-default branch is done

Hello,

from my point of view, the dont-save-plaintext-passwords-by-default
branch is done. Many, many thanks to everyone who contributed helpful
feedback and suggestions, especially to Daniel Shahaf, Mark Phippard,
David Glasser and Karl Fogel. Without these guys this branch wouldn't
be where its at now.

Summary of the functionality implemented:

  Add a 'store-plaintext-passwords' option, which can be set to
  'yes', 'no', or 'ask' (which is the default). If the option
  is set to 'ask', ask the user before saving plaintext passwords
  to disk. This is done from a callback that should be implemented
  by all clients.
  
  If a client does not implement the callback, and does not provide
  an explicit default value, we default to storing plaintext passwords.
  I don't like this, but it's a compromise because we don't really want
  the semantics of the old API to change retrospectively.
  We can, however, change this default anytime by tweaking a single
  line of code, should we decide to do so. The old interfaces have
  been deprecated.

  Provide an implementation of the callback for our command line
  client, which prints a warning and a prompt, which looks like this:

  Authentication realm: <svn://localhost:3690> My First Repository
  Username: harry
  Password for 'harry':
  -----------------------------------------------------------------------
  ATTENTION! Your password is going to be stored to disk unencrypted!
  -----------------------------------------------------------------------
  You can get rid of this warning by editing /home/stsp/.subversion/config
  and setting 'store-plaintext-passwords' to either 'yes' or 'no'.
  Store password unencrypted (yes/no)?
  
  The option can be specified both in the ~/.subversion/config
  file (global default), and the ~/.subversion/servers file,
  where the global default can be overridden on a per-server basis.
  The option is ignored if it occurs in the [global] section of
  the servers file, to avoid ambiguous global defaults.

Please consult the log messages of the branch for detailed list
of changes:

  svn log --stop-on-copy \
    http://svn.collab.net/repos/svn/branches/dont-save-plaintext-passwords-by-default

You can get the diff like this:

  svn diff http://svn.collab.net/repos/svn/trunk@30726 \
           http://svn.collab.net/repos/svn/branches/dont-save-plaintext-passwords-by-default

I'd like to merge this into trunk, but will wait patiently for a
few +1's before doing so. Since this chance has been quite
controversial, I want to make sure we have something here that
is accepted by a large majority of the community.

Thanks,
