Add tldap_context_[gs]etattr
This adds the ability to attach extended information to a tldap_context. This will become useful once we start to do automatic reconnects for example, a callback function might want attach a pointer to credentials so that it can rebind. The initial user of this will be a cached rootdse, so that things like the ability to do paged searches can be cached.
