Improve some check logic in pg_receivewal
The following things are improved:
- Fetch the system identifier from the source server before any
WAL streaming loop. This triggers extra checks to make sure that
pg_receivewal is still connected to a server with the same system ID
with a correct timeline.
- Switch umask() (for file creation mode mask) and RetrieveWalSegSize()
(to fetch the size of WAL segments) a bit later before the initial
stream attempt. If the connection was done with a database,
pg_receivewal would fail but those commands were still executed, which
was a waste. The slot creation and drop are now done before retrieving
the segment size.
