largefiles: pay attention to dropped standin files when updating largefiles
Previously, the largefile for a dropped standin would be deleted here, and then
restored from the cache. This had the effect of clobbering uncommitted changes
if a revert caused the file to be forgotten, which is not what happens with a
normal file. Now the removal and update is skipped for dropped largefiles, and
the corresponding standin is deleted from disk.
This was noticed when working on issue5738 because the forgotten standin files
were left behind, and that changes the behavior of the next rename to that
directory. My first attempt was to cleanup the standins before calling this.
That failed, because this function deletes the largefile if the corresponding
standin is missing.
This function is called by the revert command, merge (and therefore update), and
patch, via the scmutil.marktouched() override. So it should be pretty narrow in
scope.
I didn't mark issue5738 as fixed because the move related issues can still
happen if the main tree and the .hglf subtree get out of sync somehow. I don't
see an easy fix for that, but that should be an edge case. If whoever queues
this thinks it is good enough to close out the bug and can cram it into the
summary, go for it.
