    Let users add their own txid suffixes

    The value of the X-Trans-Id-Extra header on the request (if any) will
    now be appended to the transaction ID. This lets users put their own
    information into transaction IDs.

    For example, Glance folks upload images as large objects, so they'd
    like to be able to tie together all the segment PUTs and the manifest
    PUT with some operation ID in the logs. This would let them pass in
    that operation ID as X-Trans-Id-Extra, and then when things went
    wrong, it'd be much easier to find all the requests in Swift's logs.

    Also, this aids debuggability when requests fail to receive
    responses. If a user is sending in their own X-Trans-Id-Extra strings,
    then that gives operators something to search for in the logs. The
    normal txid won't work since that's in the response, but the client
    didn't receive one.

    Swift will only use the first 32 characters of X-Trans-Id-Extra so
    that its log lines stay a manageable length. Also, it's URL-quoted so
    that users cannot inject double quotes into X-Trans-Id-Extra and screw
    up log parsers.
