Making it an error for get-sth-consistency to be invoked with second >= tree_size as per RFC spec: 4.4 "Both tree sizes must be from existing v1 STHs (Signed Tree Heads)".  Also making it an error for get-entries which is allowed under RFC spec 4.6. The "start" and "end" parameters SHOULD be within the range 0 <= x < "tree_size" as returned by "get-sth" in Section 4.3.  Logs MAY honor requests where 0 <= "start" < "tree_size" and "end" >= "tree_size" by returning a partial response covering only the valid entries in the specified range.
