Bugzilla #41831:

- Add support font auto-detection (easier font configuration) including a font cache to speed up the auto-detection process.
- Refactoring of the configuration code: All Avalon configuration stuff is extracted into separate "Configurator" classes.
- Refactoring of the FOURIResolver.
Submitted by: Adrian Cumiskey <fop-dev.at.cumiskey.com>

Changes to the patch by jeremias during the review:
- Font cache simplified (Java object serialization instead of XML), functionality fixed and moved to the fonts.package.
- Relocated default cache file location to user directory.
- Fixed the font configuration for PDFDocumentGraphics2D/PDFTranscoder that got lost with the patch.
- Fixed a problem with having a non-file URL as font base URL.
- Simplified RendererContextInfo stuff to make it easier to understand.
- Fixed handling of Type 1 fonts in auto-detection.
- Reduced verbosity of font-related log output.
- Updated Jakarta Commons IO to version 1.3.1 (the patch depends on it)
- Various javadocs improvements
