Fix pg_current_logfile() to not emit a carriage return on Windows.
Due to not having our signals straight about CRLF vs. LF linetermination, the output of pg_current_logfile() included a trailing\r on Windows. To fix, force the file descriptor it uses into textmode.While here, move a couple of local variable declarations to makethe function's logic clearer.In v12 and v13, also back-patch the test added by1c4e88e so thatthis function has some test coverage. However, the 004_logrotate.pltest script doesn't exist before v12, and it didn't seem worth addingto older branches just for this.Per report from Thomas Kellerer. Back-patch to v10 where thisfunction was added.Discussion:https://postgr.es/m/412ae8da-76bb-640f-039a-f3513499e53d@gmx.net
