[PATCH v2 08/25] binman: Rename ExpandToLimit to extend_to_limit

[Simon Glass <sjg@chromium.org>]

The word 'expand' is used for entries which generate subentries. It is
also used for entries that can have an '_expanded' version which is used
to break out its contents.

Rather than talking about expanding an entry's size, use the term
'extending'. It is slightly more precise and avoids the above conflicts.

This change renders the old 'expand-size' property invalid, so add an
error check for that.

Changes in v2:
- Add patch to rename ExpandToLimit to extend_to_limit
