Logic for comparing log graphs is duplicated across test scripts.

This patch consolidates such logic into lib-log-graph.

The proposed log message is a bit thin.  It does a bit more than
"conslidates", doesn't it?

For example, discarding the singular/plural compat stuff from the
t4202's version is OK, but we should record that is what we did in
the log message to allow readers to notice.

Nicely named.

> +	sed 's/ *$//' >output.sanitized < output &&

Lose SP not just on the output redirection but also on the input
redirection.  I.e.

	sed 's/ *$//' >output.sanitized <output &&

Or you can lose the input redirection altogether as "sed" knows to
treat remaining command line arguments as names of its input files,
i.e.

	sed 's/ *$//' output >output.sanitized &&

People may find the latter easier to read.  I personally do not have
strong preference either way as long as it is consistent.

	sanitize_log_output <output >output.sanitized &&

(I won't repeat)

Hmm, is this correct?  The input goes to expect but the new helper
you wrote, lib_test_cmp_graph, won't see it.
