Use javadoc extlink across the board
Make line lengths <= 80 chars
Add top-level grouping sections
Note the corresponding Ant target(s) for each component
Fix double whitespaces and add Javadoc links
Remove description from OME ant targets

These targets are meant to be confusing. Removing description prevents them
from being listed in the output of `ant -p`
Homogeneize description of ant targets
Use lowercase for xsd-fu and specification

Imspector OBF: support version 5 stacks
cpp: xerces: Simplify Xerces-C wrapping and add writer helpers

The base class now uses a std::shared_ptr with a custom deleter.
For managed types, the deleter calls the release member function
of the type.  For unmanaged types, the deleter is a no-op.  This
means the wrappers no longer need to be templates and so the
implementation is rather simpler than previously.  The other
change to the design is that the shared_ptr construction with
custom deleter is moved out of the base class and into the
top-level wrapper, allowing the behaviour to be changed, e.g.
for NodeList.

Update Document helpers to add utility functions for writing
Document and Node elements to strings, streams and files.
