[Development] Categorized logging inside Qt

[Frederik Gladhorn]

Hi all,

I just started to port accessibility to the new and shiny categorized logging.
http://blog.qt.digia.com/blog/2014/03/11/qt-weekly-1-categorized-logging/

I'd propose we decide on a certain style of declaring categories.

A quick grep shows that we already have some variety, I'd like to unify this 
before Qt 5.3 is out of the door. I actually saw a patch adding DBG_FOOBAR as 
new category, that made me wonder about which style we should use.

angle/src/d3dcompiler/main.cpp:61:Q_LOGGING_CATEGORY(QT_D3DCOMPILER, 
"qt.angle.d3dcompiler")
corelib/doc/snippets/qloggingcategory/main.cpp:49:Q_LOGGING_CATEGORY(QT_DRIVER_USB, 
"qt.driver.usb")
plugins/platforms/windows/qwindowscontext.cpp:82:Q_LOGGING_CATEGORY(lcQpaWindows, 
"qt.qpa.windows")
plugins/platforms/windows/qwindowscontext.cpp:83:Q_LOGGING_CATEGORY(lcQpaBackingStore, 
"qt.qpa.backingstore")
plugins/platforms/windows/qwindowscontext.cpp:84:Q_LOGGING_CATEGORY(lcQpaEvents, 
"qt.qpa.events")
plugins/platforms/windows/qwindowscontext.cpp:85:Q_LOGGING_CATEGORY(lcQpaFonts, 
"qt.qpa.fonts")
plugins/platforms/windows/qwindowscontext.cpp:86:Q_LOGGING_CATEGORY(lcQpaGl, 
"qt.qpa.gl")
plugins/platforms/windows/qwindowscontext.cpp:87:Q_LOGGING_CATEGORY(lcQpaMime, 
"qt.qpa.mime")
plugins/platforms/windows/qwindowscontext.cpp:88:Q_LOGGING_CATEGORY(lcQpaInputMethods, 
"qt.qpa.inputmethods")
plugins/platforms/windows/qwindowscontext.cpp:89:Q_LOGGING_CATEGORY(lcQpaDialogs, 
"qt.qpa.dialogs")
plugins/platforms/windows/qwindowscontext.cpp:90:Q_LOGGING_CATEGORY(lcQpaTablet, 
"qt.qpa.tabletsupport")
plugins/platforms/windows/qwindowscontext.cpp:91:Q_LOGGING_CATEGORY(lcQpaAccessibility, 
"qt.qpa.accessibility")
