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

Removed the FO document pre-processing step that was adding ptr and creating a reduced FO tree.
* Removed addPtr.xsl and reduceFOTree.xsl
* Implemented Common Accessibility properties on objects that support them
* Added a special implementation of FOEventHandler to build the structure tree
* Added mockito library and its dependencies
* Added mocks for some FO nodes and properties
* Removed FOTreeUnitTester and converted it into a re-usable FODocumentParser class
* Re-worked table FO test cases accordingly

Bugfix: NPE after PDFDocumentGraphics2D.create() due to missing font setup and other missing initializations.
Bugfix: Properly handle state in PDFGraphics2D.drawString().
Added an example class demonstrating the use of PDFDocumentGraphics2D.

Bug relates to PCL painter thread safetly. Previous fix in rev 895012 worked by synchronizing methods of a static instance of Java2DFontMetrics. This fix uses a unique instance for per thread.

Removed the lastMediumMap variable and the check to omit the IMM if it doesn't change. I wonder why I came up with that. This can lead, among other things, to problems when an AFP file is split.
Bugfix: select the right font to paint replacement glyphs. This used to paint some characters on top of each others when a font with an auxiliary encoding was active.
Bugfix: AFMFile sometimes indirectly caused wrong assignments of char widths to code points in a single-byte encoding due to mapping multiple characters to the same code points (see overridePrimaryEncoding).
Removed fallback mechanism in AbstractCodePointMapping. This is superfluous now that SingleByteFont handles all substitutions. This actually fixes a bug: the glyph "minus" was painted using "hyphen" but used the width of "minus" due to this fallback mechanism.
Fixed a multi-threading bug for SVG images included through svg:image inside SVG document. Similar to the fix required in PDFImageHandlerSVG. The SVG DOM must be cloned because Batik attaches the CSS parser to the DOM tree and manipulates the same.
Bi-level images that are generated as page segments and don't need to be resampled produced garbled output because the size of the image data got set to wrong values.

The code is now checking re-use of an already encoded image before actually encoding it. Before, the image was encoded in every case, but only really embedded the first time.

Painting state was not properly handled when painting text runs which could lead to missing color setters and therefore wrong font colors.
Removed save/restoreGraphicsState from PDFTextUtil as that doesn't update the painting state. Instead the code is now using equivalent methods from PDFGraphics2D.
