Basically, I replaced all methods in the font_metrics namespace by a proper virtual interface FontMetrics. The FontLoader is _the_ container for FontMetrics.
This patch should also bring some optimizations in a number of place in the code. This is because we do not need any more to search for the LyXFont at each font_metrics call. In effect, the speed advantage is not as sensible and this is a bit deceiving considering that this was my primary motivation behind the patch. But I like the patch anyway as it cleans up the relation and interfacing between fonts, metrics and frontends.
* frontends/FontMetrics.h: new virtual interface. Renamed from font_metrics.h
* qt4/GuiFontMetrics: corresponding qt4 implememtation. Renamed from qfont_metrics.C. The smallCaps particular case treatment has been transfered here as well as the width cache for MacOSX and Windows.
* qt4/QLPainter.C: the smallCapsText has been reworked to return the width of the drawn text.C
all other files: replace font_metric helper function call with corresponding FontMetrics method calls.

- src/support/unicode.[Ch]: new files with functions for converting
to and fro ucs4, ucs2 and utf8.
- src/support/docstring.h: specialization of basic_string that
holds a uint32_t internally.
- Several functions changed to use char_type instead of char or unsigned char.
- Qt3 and Qt4 sends ucs2 on to core
- Gtk sends ucs4 on to core
- Read and write utf-8 .lyx files.
- font_metrics and painter updated to handle ucs4 chars as input.
- Quite a bit of ugly compability code, conversion string->docstring, etc.
- Have fun...

* QLPainter::start() now re-initialize qp_
* QLPainter::end() now end qp_

Don't use multiple QPainter::begin on the same QPaintDevice.

- Cursor handing is done on the server -> *cursor are
QPixmap
- Use new drawScreen and copyScreen methods.
* QWorkArea.[Ch]:
- Pixel manipulation is done on the client -> paint_device_ is a
QImage
- an intermediate Screen device is updated whenever expose is called
-> sreen_device_ is a QPixmap. This screen_device is the one that is
painted on screen in QWorkArea::repaintEvent().
- new update, drawScreen and copyScreen methods.
* QLPainter.C: use the new paintDevice interface.
