* Update swift from branch 'master'
  - Merge "Allow "static symlinks""
  - Allow "static symlinks"
    
    ... by embedding something like `If-Match: <etag>` semantics in the
    symlink.
    
    When creating a symlink, users may now specify an optional
    X-Symlink-Target-Etag header. If present, the etag of the final object
    returned to the client will be checked; if it does not match the
    X-Symlink-Target-Etag header, a 409 Conflict error will be returned to
    the client.
    
    Note that, unlike "dynamic symlink" behavior, the target object must
    exist with the matching Etag for the "static symlink" to be created.
    
    Since we're validating the Etag anyway, we also set the content-type of
    the symlink to match if the client didn't otherwise specifiy and send
    the etag & content-length along to the container listing as well.
    
    Bonus goodness:
    
    - Tighten assertions on Content-Location
    - Get rid of swift.source-sniffing by making versioned_writes
      symlink-aware ('cause I'm going to want to make it symlink-aware
      later anyway)
    - Allow middlewares left of symlink to set their own
      Container-Update-Override-Etag when creating a symlink
    - Set dynamic symlink content type if client doesn't supply something
