static-http: mimic more closely localrepo (issue2164: allow clone -r )

* httprangereader: name, __iter__ and close are needed to mimic file object
* static-http opener:
    - disallow write/append modes
    - add (unused) atomictemp parameter
* static-http repo:
    - root attribute is needed for localrepo.dirstate()
    - _branch* attributes are required for commitctx and branchmap calls
* tags: force repo.opener.__iter__ call earlier to force httprangereader
  to try to read the cache early, to avoid raising IOError later.
