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.

* BufferView
- layoutChanged: new boost signal.
- LyXView owner(), owner_: deleted
* text3.C
- emit BufferView::layoutChanged instead of calling LyXView::setLayout directly
- LFUN_MOUSE_RELEASE: delete LyXView updateMenubar() and updateToolbars() direct calls.
The update is of both bars is done in WorkArea::dispatch().
* WorkArea.C
- dispatch(): add LyXView updateMenubar() call.
* LyXView
- connects to BufferView::layoutChanged directly to Toolbars::setLayout()
- setLayout(): deleted.
* qt4/GuiImplementation: modify BufferView construction (without LyXView).
All other files: cleanup header declaration of LyXView.h

Most of qt3 and gtk should stay compilable except for LyXView.h because the LyXFunc instance has been transferred to Application.
* frontends/Application: new class aimed to be the one unique interface between the frontend and the kernel. Contains one global pointer to the unique instanciation theApp.
* frontends/qt4/GuiApplication: renamed from qt4/Application, the qt4 specialisation of the Application class. Contains one global pointer to the unique instanciation guiApp (equal to theApp but pointing to a GuiApplication instead).
* frontends/qt4/lyx_gui.C: most of the code has been moved to Application and GuiApplication
All other file: adapted to new API.

The associated WorkArea is then responsible to connect these signals to its LyXView parent.
* BufferView:
- showDialog, showDialogWithData, showInsetDialog: new boost signals
* LyXView:
- connectBufferView(), disconnectBufferView(): new method in charge of the connection/disconnection of the above signal to associate private methods (showDialog(), etc).
* WorkArea
- setBufferView(): will connect/disconnect the BufferView to its LyXView parent.

- 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...

The performance may suffer a bit because we do the second drawing step in all cases. This could be possibly optimized out by checking the return value of the BufferView::update() method in "lyxfunc.C:1610". But it is maybe better to keep those two parts of the frontend ignorant of each other: the event handling and the drawing.
BufferView:
* needRedra(), need_redraw_: deleted.
* updateMetrics(): now public.
* update(): only do the first drawing step. Returns true if a full updateMetrics is needed before drawing on screen.
WorkArea:
* redraw(): no check on BufferView::needRedraw(), call updateMetrics() unconditionally.
* processKeySim(): uneeded "redraw()" call commented out. When/if the call to LyXView::redrawWorkArea() in "lyxfunc.C:1610" is not needed anymore, this line should be uncommented out.
