Extension methods removed

The extension method implementation has been removed from the 5.8 branch again, its quality and performance was way below expectation:

Clumsy declaration syntax
The xp::extensions('lang.types.ArrayList', __CLASS__); in the static initializer block looks weird, it should be replaced by a more syntax-like feature, e.g. a base class (like enums), annotations (like the new generics implementations) or a construct like export().
Full import
As of point where a class gets used, its extension methods were globally available, not only for the scope they were used in. This may lead to confusion about methods "appearing" on objects all of a sudden.
Slow implementation
The first shot came with a serious performance impact, more needed to work around #2

That said, RFC #0189 has been reset to draft status.

It's not dead though, if the issues can be resolved, it will be re-added again.
