Simplify SortTocFromFile() by removing fixed buffer-size limit.
pg_restore previously coped with overlength TOC-file lines using some
complicated logic to ignore additional bufferloads. While this isn't
wrong, since we don't expect that the interesting part of a line would
run to more than a dozen or so bytes, it's more complex than it needs
to be. Use a StringInfo instead of a fixed-size buffer so that we can
process long lines as single entities and thus not need the extra
logic.
