Documentation: added warnings that "enable_original_recipient

result under the original probe destination address, if it
is changed by aliasing or canonical mapping. Files:

= no" prevents Postfix <= 3.2 from saving the address
verification result under the original probe destination
address, if it is changed by aliasing or canonical mapping.

proto/postconf.proto.
Cleanup: don't store an empty address in the verify cache
(this could happen with "enable_original_recipient = no").
File: global/verify.c.
20170729
Cleanup: the setting "enable_original_recipient = no" no
longer breaks address verification for aliased addresses.
This does not change the behavior of the X-Original-To
header and of recipient deduplication. The fix is to always
store the original recipient in queue files. Some other
changes were needed to move ownership of the var_enable_orcpt
parameter from the cleanup daemon to the global library.
