[TYPO3-ect] 4.1.0: Request parameters could not be validated

[Elmar HInz]

Hi,

I just tested lib/div with 4.1.0. When sending a request I get an error
message: 

Reason: Request parameters could not be validated (&cHash empty)

It seems there is now an additional check in for parameter validation. So
currently lib/div will not run with 4.1.0. A will have a look how this can
be fixed. I don't know if this behaviour is a real improvement and gives
more security. Did we had a security hole in the past? 

I fear some extensions will break. The handling of lib/div link object
will probably become more difficult and switching between caching and non
caching (USER/USER_INT) for the same extension could also become more
difficult.  I hoped they would simplify tslib_pibase so that it would
become more simple for extension programmers to build proper caching
extensios. It seems the opposite happens.
