Component clarification

[Daniel van Vugt]

OK, let's try again. There seems to be reasonable agreement that at 
least some components are poorly named and therefore confusing. Of 
course, any change requires significant search and replace in the least 
so I'd like to discuss it before any proposals occur.

How about...

mir::surfaces:: --> mir::core::
This component already represents the core platform-independent state 
and implementation code. So rather than call it "surfaces" which 
confuses the numerous existing Surface classes (75% of which are not in 
the "surfaces" component), why not call the component "core" or some such?

mir::graphics::*:: --> mir::platform::*:: or
mir::graphics::*:: --> mir::*::
The whole project is about graphics so we need to stop calling one 
component "graphics". This component already represents the 
platform-specific code. So why not name it "platform" or even remove the 
word "platform"/"graphics" completely and use the actual platform name 
mir::gbm::, mir::android:: etc?
