    Better escaping for GET /v1/a?format=xml.

    Commit 8f9b135 fixed a bug where an XML attribute could have arbitrary
    characters jammed into it, resulting in a document with arbitrary
    tags... and it did remove the ability to get an arbitrary XML document
    out of the object server. However, it left a couple of ways to get a
    malformed XML document, one example of which is an account named ".

    This fixes up the remaining ways and ensures you always get a
    well-formed XML document in the account-listing response. Also, it
    adds a unit test for the escaping of the container name; this was
    already working, just untested.

    If you look in the discussion for bug 1183884, you'll see that the
    review comments there are basically "seems good, but could use a unit
    test". (The astute reader will note that I am one of the guilty
    parties in that review.)

    I found this bug while writing the missing unit test.

    The moral of this story is left as an exercise for the reader.

    Fixes bug 1183884 harder.
