Move WAL warning
When running pg_basebackup with -x to include all transaction log, the
server will still throw a warning about xlog archiving if it's not
enabled - that is completely irrelevant since pg_basebackup has
included it already (and if it was gone, the base backup step itself
will fail - actual error and not warning).
This patch moves the warning from do_pg_base_backup to pg_base_backup,
so it still shows when using the explicit function calls, but goes
away when using pg_basebackup.
Objections?

For the sake of consistency, how about moving the "pg_stop_backup
complete, all required WAL segments have been archived" notice too?

Well, it goes out as a NOTICE, so by default it doesn't show.. But
yeah, for code-consistency it makes sense. Like so, then.

Thinking some more about it, I realized this is not going to be enough
- we need to be able to turn off the waiting for WAL segment as well,
in the case when you're streaming the log. Thus, it needs to be
controllable from the backup client, and we can't just assume the
default is ok.
Attached is an updated patch that adds a NOWAIT option to BASE_BACKUP,
that turns off the waiting. If it's set, it also doesn't warn about
not being able to wait in the case when there is nothing to wait for,
so this is a replacement for the previous patch.

Back to your original complaint. When -x option is specified, pg_basebackup
should use NOWAIT option in BASE_BACKUP command to send to the server?

Oh yeah, I put that in the wrong patch - it's in my patch to do the
streaming wal. I'll extract it and apply it separately, in case the
other stuff isn't finished.
