revlog: extract function for getting node from known-to-exist rev Many of the calls to index_node() (which converts a rev to a nodeid) are done with a rev that's know to exist. If the function fails, there's something really wrong and we should just abort. This was done in only one place. This patch starts by extracting that code to a function that we can reuse in later patches. Differential Revision: https://phab.mercurial-scm.org/D3456
