[sudo-workers] sudo 1.7a1 released

[Todd C. Miller]

This is the first alpha version of sudo version 1.7.  I'm labeling
this as alpha not due to stability issues but simply because it is
not feature frozen yet (there are some LDAP enhancements still to
be done).

What's new in Sudo 1.7?

 * Rewritten parser that converts sudoers into a set of data structures.
   This eliminates a number of ordering issues and makes it possible to
   apply sudoers Defaults entries before searching for the command.
   It also adds support for per-command Defaults specifications.

 * Sudoers now supports a #include facility to allow the inclusion of other
   sudoers-format files.

 * Sudo's -l (list) flag has been enhanced:
    o applicable Defaults options are now listed
    o a command argument can be specified for testing whether a user
      may run a specific command.
    o a new -U flag can be used in conjunction with "sudo -l" to allow
      root (or a user with "sudo ALL") list another user's privileges.

 * A uid may now be used anywhere a username is valid.

 * The "secure_path" run-time Defaults option has been restored.

 * Password and group data is now cached for fast lookups.

 * The file descriptor at which sudo starts closing all open files is now
   configurable via sudoers and, optionally, the command line.

 * Visudo will now warn about aliases that are defined but not used.
