TYPO3 Core

With 6.0 the bootstrap related core code was split into small methods
and transferred to a group of encapsulating classes.
While this is an important step to get a flexible and maintainable
bootstrap in the end, this process is not completed and still misses
for example a real concept for scopes.
In order to have freedom for continued development with future TYPO3
core versions, the whole current API should be made protected as much
as possible for now.
The patch groups methods used in all scopes in bootstrap wrapper
methods and makes the business methods protected. The whole API and
all affected classes are marked as "internal", together with a
warning that this API will change in the future and shouldn't be
used by 3rd party code that is not under core control.
