Symlinks for the Freelance root.afs volume

Tonight's daily builds add a new feature.  When Freelance mode is used a 
locally constructed root.afs volume is created instead of mounting the 
root.afs volume of the default cell.  Previously the fake root.afs could 
only support mount points.  This was a problem for sites which depend on 
the use of symlinks in the root.afs volume.  Now it is possible to 
create symlinks in the local root.afs volume which are persistent across 
sessions.

   >symlink make \\afs\all\link \\afs\all\athena.mit.edu\user\j\a\jaltman

   >symlink list \\afs\all\link
   '\\afs\all\link' is a symlink to 'athena.mit.edu\user\j\a\jaltman'

   >symlink rm \\afs\all\link

The symlinks are stored in the registry at:

   HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks

There is still a bit more to do.  Specifically, there is nothing to 
prevent any user from creating symlinks nor am I sure that the Explorer 
Shell extensions work.

As usual the daily builds are located at:

    http://web.mit.edu/~jaltman/Public/OpenAFS/
    /afs/athena.mit.edu/user/j/a/jaltman/Public/OpenAFS/
    \\AFS\athena.mit.edu\user\j\a\jaltman\Public\OpenAFS\

Todays builds are digitally signed with my [email protected] cert.  I have 
ordered a signing certificate from Thawte for Secure Endpoints Inc. 
which I will use in the future.  This will allow the signatures to be 
verified by Windows without additional work on the part of the end user 
and the binaries can be timestamped as well as signed.
