Add --delattr option to complement --setattr/--addattr
Add a --delattr option to round out multi-valued attribute
manipulation. The new option is available for all LDAPUpdate based
commands. --delattr is evaluated last, it can remove any value
present either in --addattr/--setattr option or in current LDAP
object.
--*attr processing was completely refactored and placed to one
independent function available for all baseldap commands. For this
purpose a missing common base class for all baseldap commands has
been implemented. The new class should serve not only for --*attr
processing but also for other common baseldap methods and
attributes.
This approach will also benefit other custom commands based neither
on LDAPCreate nor LDAPUpdate. They can easily integrate --*attr
option processing when needed.
