redesign the header API

I'm quite satisfied with this right now (though this doesn't say
anything about how I feel about it tomorrow), but it's ugly that some
guts (headers.Base) are exposed in the public API.

-//NewMetadata constructs a Metadata instance from a list of key-value pairs
-//with compact syntax. It is recommended over a map literal since it correctly
-//formats keys with textproto.CanonicalMIMEHeaderKey(). For example:
-//
-//    m = NewMetadata(
-//        "color", "blue",
-//        "size", "large",
-//    )

-//    m = make(Metadata)
-//    m.Set("color", "blue")
-//    m.Set("size", "large")

-//NewMetadata panics if it is called with an odd number of arguments.

-//
-//For account or container metadata, a key which has been deleted with Del() will
-//remain unchanged on the server. To remove the key on the server, use Clear()
-//instead.
-//
-//For object metadata, deleting a key will cause that key to be deleted on the
-//server. Del() is identical to Clear() in this case.
