Bugfix for ICC color profile parsing in JPEG images.

The about attribute must have the "rdf" namespace prefix.
Adobe Acrobat uses an outdated namespace URI for the PDF/A identification, so do the same as Adobe Distiller: write the PDF/A identification twice, once with each namespace URI. Reason: Acrobat is probably the best tool to verify PDF/A conformance right now. jHove covers only part of ISO 19005-1.

Made the loading of user-specified hyphenation patterns usable again and plugged it into URI resolution.
Backwards-compatibility should be maintained.
PatternParser now uses JAXP to get the SAX parser.
Moved the hyphenation pattern cache into a separate class so I can easily plug it into FopFactory later instead of having static variables.
Added serialVersionUID to HyphenationTree. Necessary because the class signature changed.
FOURIResolver does not complain about "file not found" on the log anymore since this should be done by the caller. Until now, this resulted in two log messages about the same problem on the log. "File not found" is still reported but only on level "debug" which might be helpful when tracking down a problem, but at least it's not a "WARNING" anymore.

Certain filter combinations in PDF could lead to invalid PDFs. DecodeParams were not properly handled.
Default filter for XMP metadata set to NullFilter as XMP metadata should always be embedded as clear-text so non-PDF-aware XMP processors can extract the metadata.
Default filter for DCT/JPEG- and CCITT/TIFF-encoded images set to NullFilter because these two compression methods already do a good job. An additional flate filter (as was applied before due to the single default) helps a just little but also adds processing time. If anyone wants to squeeze every possible bit out of the PDF you can use the following in the user configuration:
<filterList type="tiff">
<value>flate</value>
</filterList>
<filterList type="jpeg">
<value>flate</value>

Added support for fixed-width spaces and kerning.
Note: letter-spacing is still implemented as before. Fixing this cannot be done without looking at space resolution as a whole on inline level.
The Character area tree object is now deprecated. Normal Text objects should be used to keep renderers simpler.
Introduced FontResolver interface to remove the dependency of FOUserAgent into the font package.
Added kerning information to the base14 fonts, Helvetica and Times. By default it is not used to keep the status-quo. Enable base14 kerning through the FOUserAgent (FopFactory after the API finalization).
Restored the production of EPS images in PDF output as PostScript XObjects.

Initial support for XMP metadata (PDF 1.4) under fo:declarations. Both xmpmeta and RDF elements can be used as root elements for XMP metadata.
Extracted DOM2SAX functionality from XMLXMLHandler into utility class since it is now reused elsewhere.
New DOMBuilderContentHandlerFactory is used to create ContentHandlers that build generic DOMs.
New DelegatingContentHandler is a convenience base class modelled after XMLFilterImpl but as passive SAX receiver. It is used by DOMBuilderContentHandlerFactory.
Refactored FOTreeBuilder. FO tree building is now in a special ContentHandler which can be replaced temporarily when handling foreign XML like SVG or XMP. Extension Elements wanting the set their own ContentHandlers (instead of using the standard FO tree building mechanism) return a non-null value in getContentHandlerFactory(). The old mechanism is still supported (MathML, Plan and Barcode4J still use that). However, SVG support is changed to use a ContentHandlerFactory.
Extension elements for xmpmeta and RDF elements making use of the new DOM build-up using ContentHandlerFactory.
XMP metadata is passed to the renderer as ExtensionAttachment to the document. Only PDFRenderer uses the XMP extension attachment at this time.
The PDFRenderer automatically builds XMP metadata based on the basic metadata information in the PDFInfo object if no explicit XMP metadata has been added to the XSL-FO document.
XMP metadata merging is not implemented because this would involve a more sophisticated XMP infrastructure. That also means that XMP metadata is not validated. It's passed into the PDF as is.
The PDF library now provides the PDFMetadata class to embed XMP metadata in PDFs version >=1.4. stream contents use a special filter list which is initially empty, so non-PDF-aware XMP readers can extract (and optionally modify) the XMP metadata.
Trivial update:
Change the wording of a few attributeWarnings -- properties aren't ignored (possible inheritance,
