lib-smtp: server: STARTTLS command: Call smtp_server_connection_set_ssl_streams() after calling the conn_start_tls() connection callback.
This is called instead smtp_server_connection_set_streams(), so that the connection is now marked as SSL-secured.
This fixes a submission-login bug that prevented client login when ssl=required.

lib-smtp: server: Fixed assertion in smtp_server_connection_next_reply() checking whether command is fully replied.
It did not handle LMTP DATA/BDAT command correctly, for which there can be multiple replies.
This fixes mixing local/remote recipients in LMTP, which used to crash:
Panic: file smtp-server-connection.c: line 610 (smtp_server_connection_next_reply): assertion failed: (cmd->state == SMTP_SERVER_COMMAND_STATE_READY_TO_REPLY && smtp_server_command_is_replied(cmd))

lib-smtp: command parser: Fix error recovery.
Input characters were not skipped upon error, meaning that error recovery would encounter these again.
This would make the parser parse the same data over and over again, yielding the same error.
This in turn caused the SMTP server application to hang in an infinite input loop, submitting error replies in the process, thereby filling up the process memory until exhaustion.
Problem seen in submission service, but LMTP is also affected.

lib-smtp: server: Fix panic when io_remove() is called too late
With submission-login the conn_disconnect() callback ends up in
login-common's client_disconnect(), which closes the file descriptor.
The io_remove() was done afterwards, which caused a crash:
submission-login: Panic: epoll_ctl(del, 18) failed: Bad file descriptor

*-login: Avoid unnecessary "OK Waiting for authentication process to respond"
These happened with SSL connections when the process was starting up.
The ssl-istream was triggering the IO callback, which was thinking that the
client was sending a command. If this happened early on before auth process
connection was finished, this caused several unnecessary notifications to
the client.

lda: Do not replace the NULL sender with a default <MAILER-DAEMON> address.
Only do this substitution locally where a NULL sender would cause problems, not everywhere else.
This e.g. causes problems when determining whether to send a rejection somewhere; attempts would be made to mail <MAILER-DAEMON>.
Also other envelope-based (Sieve) tests would get confused.

LAYOUT=fs: Fix listing prefix/INBOX
Removed some confusing special case code that didn't seem to work very well.
Implemented this now properly so that prefix/INBOX is listed as \NoSelect
mailbox whenever it has children.
It's not actually possible to differentiate between INBOX and prefix/INBOX
in the storage for a inbox=yes namespace, because they both are converted
into the same storage_name=INBOX.
