158facf6d5 Use multilib rules to look for a 64-bit group plugin on failure. 
If sudo_dso_load() fails on a 64-bit system, try to load a 64-bit
native version of the file using system-dependent multilib rules.
If we don't support multilib on the platform, check for a version
of the file that ends in "64" before the .so suffix.

85fef8b50f Add sudoers option to perform authentication even in non-interative mode. 
If noninteractive_auth is set, authentication methods that do not
require input from the user's terminal may proceed.  It is off by
default, which restores the pre-1.9.9 behavior of "sudo -n".

characters until a newline or carriage return is found in the input
or an output character is received.

that can interact with the askpass program.  GitHub issue #112.
