Refer to 6384805: use AttributesImpl instead of AttributeList

Refer to the following change history:

Patch for CR 6384805 on 01/12/2007. Implementation of xsltc.runtime.AttributeList was buggy, it mixed prefixes and URIs. Since it was pretty memory inefficient as well, I modified the code to use AttributesImpl helper from the SAX package (already part of JAXP). Moreover, I've modified the places where attributes are added to make sure that their URIs are passed.

On 5/24/2007, Restoring a few classes that were lost in the last pruning. Namely, Constants from templates, ExpressionContext from extensions and a few classes from the lib package. Also updating SyntaxTreeNode and Parser to eliminate any references to the old xsltc.runtime.AttributeList class which was replaced by sax.helpers.AttributesImpl.
