Subject: [PATCH] journal-remote: fix counting of events written

After recent changes the number was always reported as 0, because
the accounting was done server_destroy(), called after the message was
already printed. But even before this change, the counts were wrong
because seqnum start at 0 only for newly created journal files, so when
appending to existing files, the calculated count was wrong anyway.

Also do some variable renaming for consistency and disable some low-level
debug messages.
