Python parts of module ldap

[Michael Ströder]

HI!

As already announced I'd like to contribute some of my LDAP-related
Python modules to python-ldap.

But I don't want to pollute the module name space with a lot of
separate names. Therefore I'd suggest that we turn the module ldap
into a directory-based module package adding more sub-modules later.

ldap/__init__.py would import all symbols from _ldap for the sake of
backward compability (like ldap.py already does today).

Comments?

Ciao, Michael.
