[Development] Heads-up: new headersclean is going in soon

[Thiago Macieira]

[See thread "A better headersclean test"]

The alpha is out and all the dependencies are in. I will try staging the new 
headersclean during tonight's night in Europe so as to avoid disruption. I 
anticipate at least one failure with some compiler combination I haven't tried 
in qtbase or qtdeclarative.

What this means: other modules whose headers are not clean will stop 
integrating. You will have to fix the headers to be clean, including the 
annoying -Wshadow warning from GCC, but not the integer size & signedness 
mismatch ones.

Unlike the -Werror for .cpp sources, this is not optional: our headers must be 
clean because our users may have unexpected warning options.
