Complain with proper error message if streaming stops prematurely

Browse Source 
In particular, with a controlled shutdown of the master, pg_basebackup
with streaming log could terminate without an error message, even though
the backup is not consistent.

In passing, fix a few cases where walfile wasn't properly set to -1 after
closing.
