[Boost-build] [V2, 1.34] Qt support issues

Hi !

The branch for the 1.34 is coming nearer and I've been thinking about 
the support for Trolltech's Qt Library.

Right now, we have a minimal toolset named "qt.jam" which provides 
rudimental support for Qt <= 3.3.5. Is does not have library name 
detection (necessary on Win32) and no support for Qt3 image embedding.
And then we have a toolset named "qt4.jam" which provides much better 
support for Qt >= 4.1. Is has support for all kinds of "moc" invocation 
and provides support for image embedding via Qt4 "rcc" resource 
compiler.

I think it would be best to rename "qt.jam" to "qt3.jam" and mark it as  
"unmaintained" or maybe "deprecated" or both.
The old "qt4.jam" should be named "qt.jam".

I think this is the last chance to do a clean switch before we switch to 
V2 and provide an obsolete toolset as "qt.jam"

I hope that this change can be made while we are in feature freeze 
because V1 has never had any "official" support for any version of Qt.

Volodya, Thomas: What are you thinking about this ?

And now for some more technical problems:

qt4.jam has an optional "prefix" parameter which defaults to QTDIR when 
not provided by the user. I'd like the prefix  (aka Qt install dir) 
parameter to be required as Trolltech officially dropped the usage of 
QTDIR with Qt4. Alls paths are compiled into the "qmake" makefile 
generator when running configure. I think we should drop QTDIR support, 
too.

And last:
I can't use qt.jam and qt4.jam side-by-side because both use the same 
"types/qt.jam" file and bjam just segfaults while trying to load both 
toolsets.
