Import MUNGE 0.5.10 as security/munge.

MUNGE (MUNGE Uid 'N' Gid Emporium) is an authentication service
for creating and validating credentials. It is designed to be
highly scalable for use in an HPC cluster environment. It allows
a process to authenticate the UID and GID of another local or
remote process within a group of hosts having common users and
groups. These hosts form a security realm that is defined by a
shared cryptographic key. Clients within this security realm can
create and validate credentials without the use of root
privileges, reserved ports, or platform-specific methods.
