[TYPO3-core] RFC: #7982: Rename TYPO3 to TYPO4 and change all libraries accordingly

[Tapio Markula]

> Problem:
> Many people confuse TYPO3 version 4.0 and later and speak of it as TYPO4.
> To accommodate these people and make their lives easier we should rename
> TYPO3 versions released since 4.0 to TYPO4.
> 
> The new versions are thus TYPO4 1.0 (TYPO3 4.0), TYPO4 2.0 (TYPO3 4.1), and
> TYPO4 3.0 (TYPO3 4.2).
>  
> To make the step complete we of course need to rename class libraries like
> t3lib to t4lib and the typo3/ folder to typo4/, too.

that would cause big headashe for XCLASSing!
Make much plugins incompatible.
