Patch to implement the namespaced antlib + other changes

           Summary: Patch to implement the namespaced antlib + other changes
           Product: Ant
           Version: 1.6Alpha (nightly)
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: peter.reilly@corvil.com


This patch implements some of the changes discussed in
the antlib discussion, http://marc.theaimsgroup.com/?t=105138763000003&r=1&w=2

This patch adds 4 new features (the code is interrelated,
but may be split).

  * adapter attribute added to typedef
  * add(Type) method added to introspection rules
  * typedef can read an xml defintion file
  * namespace support for xml defintions (antlib:)

So one can do
<project xmlns:acme="org.acme.anttasks">
   <acme:hello>
      <path path="build.xml"/>
   </acme:hello>
</project>

where the class path contains the org/acme/anttasks/antlib.xml
and the antlib.xml file contains:

<antlib>
   <typedef name="hello" classname="org.acme.anttasks.Hello"/>
</andlib>

The patch file is a tared gzip file. and contains
a patch file, and a set of new files.
see the "adaptor.make" file in the tar file for
the list of changed files and the new files.
See the unit test "src/etc/testcases/taskdefs/typedef2.xml"
for sample usages.

ToDo: add in support for ant-type polyizm and addConfigured(Type).
      also more error checking and unit tests.
