[split] twitter-server-internal: Default Dtab, and a hooking mechanism Install a default Dtab for twitter-server-internal users. We expose an API to install the Dtab for projects that do not yet use the twitter-server-internal directly.

A new flag, -dtab.add, is exposed to add entries to the
base dtab. This may change to expose the entire base dtab.
Note that even without this support, one can effectively install
a new base dtab by adding -dtab.add ???/->fail!,..???

During testing, I also discovered that the current ServerSet
implementation may throw an exception on permissions failure.
(This seems bad: watching a serverset should be a read-only op.)
I???ve worked around this by a fixed retry mechanism. The real fix
is ServerSets2, which does not attempt to create ZK directories.
