This PR adds some hardening in the lower levels of the protocol stack, to bail early on invalid data. Primarily, attacks that this PR protects against are on the "annoyance"-level, which would otherwise write a couple of megabytes of data into the log output, which is a bit resource intensive.

This PR fixes an issue in chain indexer. Currently chain indexer will
validate whether the stored data is canonical by comparing section head
and canonical hash. But the header of the checkpoint may not exist in
the database. We should skip validation for sections below the
checkpoint.
