Make ldap2 class work as a client library as well.

Move the user-private group caching code out of the global config and
determine the value the first time it is needed.

Renamed global_init() back to get_schema() and make it take an optional
connection. This solves the problem of being able to do all operations
with a simple bind instead of GSSAPI.

Moved the global get_syntax() into a class method so that a schema
can be passed in.

If a schema wasn't loaded during the module import then it is loaded
when the connection is created (so we have the credntials needed for
binding).
