do a cleanup commit after moving data from or to a git remote

Added Annex.cleanup, which is a general purpose interface for adding
actions to run at the end.

Remotes with the old git-annex-shell will commit every time, and have no
commit command, so hide stderr when running the commit command.

   * Store web special remote url info in a more efficient location.
   * Deal with NFS problem that caused a failure to remove a directory
     when removing content from the annex.
-  * Avoid repeated location log commits when a remote is receiving files.
-    Done by adding a oneshot mode, in which location log changes are
-    written to the journal, but not committed. Taking advantage of
-    git-annex's existing ability to recover in this situation. This is
-    used by git-annex-shell and other places where changes are made to
-    a remote's location log.
+  * Make a single location log commit after a remote has received or
+    dropped files. Uses a new "git-annex-shell commit" command.
   * To avoid commits of data to the git-annex branch after each command
     is run, set annex.alwayscommit=false. Its data will then be committed
     less frequently, when a merge or sync is done.
