Associate structure tree elements directly to render content
* Defer the binding of PCData to struct elems using a placeholder mechanism.
* Translate text nodes to marked-content sequences in IF structure tree.
* Replace ptr with structure tree element.
* Re-order table footers so they appear at the end of the structure tree.

Removed the DOM representation of the structure tree.
The structure tree is now directly converted into corresponding PDF objects.
When going the IF route, the structure tree is stored in the form of SAX events that will be re-played when it's time to stream them into the output. This may still change.
* Extracted RFC3066 methods from XMLUtil into new LanguageTags class that can be re-used in a non-XML context.
* Dropped support for accessibility in the old Area Tree XML.
* Added support for the xml:lang property on fo:root, so that the global language can be set for the document without retrieving the language from the first page-sequence.
* Renamed StructureTreeBuilder into more appropriate StructureTreeEventHandler (same for applicable sub-classes)
* Renamed StructureTreeBuildingFOEventHandler into FO2StructureTreeConverter and added test case
* Added test cases for classes in the StructureTreeEventHandler hierarchy

Issue an error when attempting to render an intermediate XML file in accessibility mode, but that file wasn't generated with accessibility (i.e., does not contain the structure tree)
Reverted changes for "ptr" to painter interface as announced in #46705. The pointer value is now provided through the IFContext so only the implementations that support it have to deal with it.
Also, the method signature changes in the renderers are now reverted. They are not necessary.
Found a few other smaller omissions (IFRenderer, IFSerializer) that didn't seem to have been merged properly from Trunk.

Added support for adding extension elements and foreign attributes on fo:page-sequence.
AFP: Added support for Invoke Medium Map (IMM).
AFP: Fixed a bug adding TLEs in DataStream (TLEs were added to the page group instead of to the page).

Changes to patch by jeremias:
- Some style fixes
- Various simplifications
- Removal of dead code
- Addressed some issues raised in Bugzilla (work in progress)
- Fixed a couple of bugs on leader handling detected while testing (an NPE remains in leader_leader-pattern_use-content.xml)

Moved area tree example to package embedding/atxml.
Created a new concatenation example for the new IF in package embedding/intermediate.
Exchanged IFRendererMaker with IFSerializerMaker.
Removed unused method getConfigurator() from document handler makers.
Extracting original nested IFException in IFParser's parse() method.
Removed obsolete IFSerializerConfiguration. Now covered by PrintRendererConfigurator.
Delegating FontInfo setter calls to mimic handlers in IFSerializer.
Fixed a bug in RendererFactory for the case when FOUserAgent.setDocumentHandlerOverride() is used.
Added a generic IFDocumentHandler proxy class (IFDocumentHandlerProxy).
Added a simple IFConcatenator helper class for simple IF concatenations (experimental).

Introduced IFContext to provide access to foreign attributes (as discussed on fop-dev).
Removed the foreign attributes map from the drawImage methods as a consequence.
Added support for foreign attributes on the page (PCL's paper-source and duplex-mode extensions).
Fixed a couple of bugs parsing the document navigation elements.
Build-time test suite now runs through.

Added page master name to IFDocumentHandler.startPage() method.
Wired together the support for out-of-order rendering (only applicable to PDF) when the intermediate format is not used (in-memory rendering).
Fixed a logical bug in IFRenderer that caused some unneeded code. Glyph adjustments (kerning, letter/word space...) were not done right. All painters fixed/adjusted accordingly.
Started implementation of the PostScript painter: Supports only text and filled rectangles so far. Work in progress...

Split IFPainter into IFDocumentHandler and IFPainter. This makes the implementation classes smaller, better allows to isolate the painting parts and helps with formats that generate one object per page (SVG, PNG etc.).
Added ImageHandlerFactory to FopFactory.
Started TIFF output in order to develop the Java2DPainter that will be needed for certain tasks when generating PCL.
Tweaked the way XML is generated for IF and SVG output.

Had to introduce "clip-rect" to handle clipping on background images, leader etc. A full viewport is probably too heavy-weight here. This is to be considered temporary pending verification with SVG and PCL implementations.
First steps at unified image handling as proposed on http://wiki.apache.org/xmlgraphics-fop/ImageSupport/ImageHandler. This shall serve as a preview to motivate early feedback if anyone is interested.
Basic external-graphic support now available for PDF and SVG painters (for PDF: RenderedImage, SVG, JPEG, CCITT and Java2D, for SVG: embedded SVG and RFC2397 data URLs containing PNG and JPEG images)
Change to IFPainter: added support for foreign attributes for the "image" tag.
PDFContentGenerator introduced to hold the most important objects for PDF generation (unification for renderer and painter).
Re-routed most image handling through the new image handling code (not fully done, yet, some code duplication remains).

Improved/fixed font setup for painters. Reduced the whole thing to pass in a fully set-up FontInfo object to reduce dependencies on the font package to the necessary.
