lib-lda: Moved duplicate handling to lib-storage.

lib-lda: Removed old smtp-client API.

lib-lda: Created tests for SMTP message submission using the smtp-client API.

lib-lda: Fix deliver_log_format variables with Sieve With Sieve it was using src_mail for getting the values, which weren't correct especially if Sieve had modified the mail.
