context: translate FilteredIndex/LookupError at repo[changeid] (API)...

context: translate FilteredIndex/LookupError at repo[changeid] (API) This partially backs out ecd3f6909184. It seems layering violation for repo[changeid] to raise storage-level exceptions transparently. Otherwise, we would have to rewrite callers to catch all of them. try: repo[rev_or_node] except (error.RepoLookupError, error.FilteredIndexError, error.FilteredLookupError): pass This would also fix filectx._changectx(), which catches FilteredRepoLookupError to fall back to the unfiltered path.
