* webdav: delete a folder with its contents
* webdav: guard the recursive delete against stale and confined paths
- propagate stat lookup errors instead of returning an error-bearing
FileInfo: OpenFile and DELETE would otherwise take the recursive
removeAll on a path whose type was never confirmed, wiping a
directory on a transient filer error
- refuse wrappedFs.Rename from or to the served root, matching the
RemoveAll guard and webdav.Dir
- normalize trailing slashes in removeAll so the delete names the
entry itself, and refuse the root for every caller
* webdav: keep file-only deletes shallow and refuse ancestor destinations
- removeAll used by OpenFile and failed-upload cleanup now deletes
non-recursively, so a folder swapped in after the stat check is not
emptied by a pending file delete
- MOVE and COPY whose destination contains the source are refused
before the handler removes the destination, which would otherwise
take the source down with it
* webdav: also refuse a destination inside the source
a MOVE or COPY into its own subtree recurses into the destination it
just created; refuse it with the same guard instead of burning the
recursion budget for a 500
* webdav: allow a shallow copy into the source subtree
a COPY with Depth: 0 creates only the destination collection and never
reads children, so it is safe inside the source; only deep copies and
moves are refused there
* webdav: refuse a copy/move whose source is unreadable
* webdav: cover the missing-source refusal in the guard test
* webdav: 500 on a source lookup failure, 404 only when absent

filer: clean up manifest resolve error propagation and add webdav test (#78)
Drop GitHub issue references from comments and trim verbose comments.
Replace the viewFromChunksOrErr helper with the existing
NonOverlappingVisibleIntervals + ViewFromVisibleIntervals at the stream
call sites, and add a WebDavFile.Read regression test for the manifest
resolution failure path.

* webdav: name the entry, not its path, in a listing
DAV:displayname carried the full path of every entry. A client that
takes displayname for the child's name - Windows Explorer does - then
looks for /dir/name under /dir and finds nothing, so a folder shows up
empty while the root, where the two spellings differ only by a leading
slash, still lists.
Readdir now builds its entries with toFileInfo like stat does, so a
listing and a lookup describe a child the same way, and the wrapper that
was trimming the sub-folder back off a name goes away with it.

* webdav: derive an ETag when nothing hashed the entry
Uploads through this gateway carry no content MD5, so filer.ETag comes
back empty and every file in a PROPFIND answered with an empty
DAV:getetag, which is not a valid entity-tag. Report it as unimplemented
instead, the way the sub-folder wrapper already did, and webdav falls
back to modification time and size. The wrapper's copy went with it - it
swallowed the stat error a caller was meant to see.
