Well, that seems to be true. I haven't look at all yet. There is about
240 of them.

Mostly there is just: *ppEnvTypeName =
CPPU_CURRENT_LANGUAGE_BINDING_NAME; (this was in all I have renamed)
with occasional test: if( ppEnvTypeName != 0 )
But sometimes there also exist things like in:
http://opengrok.libreoffice.org/xref/components/extensions/source/preload/services.cxx#59
That doesn't seem interesting to me, but I don't know, maybe it
actually does something relevant.

And default is: throw loader::CannotActivateFactoryException.
There always has to be some function.
But it's only used to set one variable in shlib.cxx.
So, if CPPU_CURRENT_LANGUAGE_BINDING_NAME can be also defined in
shlib, we could use that directly to set the variable.

I may be missing something but if not I'd just remove
component_getImplementationEnvironment if it is not doing something
special and set the variable directly in shlib.
