revlog: split the content verification of a node into a separate method

This will be used by LFS to tune what is skipped.

In the future, this could also be used by LFS to indicate which nodes tagged
with `skipread` are simply in need of a blob fetch, so that they can be done in
a batch later.  (Currently, `skipread` also indicates censored data and errors.)
Additionally, it could be used to cache the sha1 hash value for each blob so
that large blobs don't need to be re-read and re-hashed if they are used by
multiple nodes.
