scmutil: make simplekeyvaluefile able to have a non-key-value first line
To ease migration from files with version numbers in their first lines,
we want simplekeyvaluefile to support a non-key-value first line. In this
way, old versions of Mercurial will read such files, discover a newer version
than the one they know how to handle and fail gracefully, rather than with
exception. Shelve's shelvestate file is an example.
