jlam bb43605988 Fix user_exists and group_exists to actually use their arguments 
instead of using the values stored in global variables.  Also,
consistently prepend variables that should be local to functions with
an underscore.

# +USERGROUP - users and groups management script
#
# Usage: ./+USERGROUP ADD|REMOVE [metadatadir]
# ./+USERGROUP CHECK-ADD|CHECK-REMOVE [metadatadir]
#
# This script supports two actions, ADD and REMOVE, that will add or
# remove the users and groups needed by the package associated with
# <metadatadir>. The CHECK-ADD action will check whether any users or
# groups needed by the package are missing, and print an informative
# message noting those users and groups. The CHECK-REMOVE action will
# check whether any users and groups needed by the package still exist,
# and print an informative message noting those users and groups. The
# CHECK-ADD and CHECK-REMOVE actions return non-zero if they detect
# either missing or existing users/groups, respectively.
#
# Lines starting with "# USER: " or "# GROUP: " are data read by this
# script that name the users and groups that this package requires to
# exist to function correctly, e.g.
#
# # USER: foo:foogrp::The Foomister
# # GROUP: foogrp
#
# The USER lines are of the form:
#
# user:group[:[userid][:[descr][:[home][:shell]]]]
#
# Only the user and group are required; everything else is optional,
# but the colons must be in the right places when specifying optional
# bits.
#
# The GROUP lines are of the form:
#
# group[:groupid]
#
# Only the group is required; the groupid is optional.
