Some admin are confused about how to give users sudoedit permission
and many users try to run sudoedit via sudo instead of directly.
If the user runs "sudo sudoedit" sudo will now treat it as plain
"sudoedit" after issuing a warning. If the admin has specified a
fully-qualified path for sudoedit in sudoers, sudo will treat it
as just "sudoedit" and match accordingly. In visudo (but not sudo),
a fully-qualified path for sudoedit is now treated as an error.
lists in sudoers. Once the headless tail queue is built up it is
converted to a normal TAILQ. This removes the last consumer of
list.c and list.h so those can now be removed.
Add sudo_printf function pointer that is initialized to _sudo_printf()
instead of requiring a sudo_conv function pointer everywhere. The
plugin will reset sudo_printf to point to the version passed in via
the plugin open function. Now plugin_error.c can just call sudo_printf
in all cases. The sudoers binaries no longer need their own version
of sudo_printf.
