Move XML code to the common library

The ManifestMerger library needs to look up the prefix to use for the
Android namespace, and the Document.lookupPrefix method is not
implemented by the Eclipse DOM implementation (which throws an
exception).  However, we have an implementation of this in the ADT
plugin.

This changeset creates a new XmlUtils class in the common/ library
(which is accessible by both ADT and the manifest merger, and the
anttasks where the manifest merger is used), and moves the namespace
prefix lookup code in there.  It also moves the XML escape methods
into that class. It also adds a new method to the ManifestMerger for
merging directly from documents (rather than files), and makes sure
that all the merging code goes via the prefix utility method rather
than calling the document.lookupPrefix method.

Finally, it moves the various string constants associated with XML
namespaces into the single XmlUtils class, since these were spread
across several different classes before (and many of them are needed
in the XmlUtils class).

The vast majority of the diffs in this changeset are related to simple
import statement changes to reflect the new locations of these
constants.
