LibIPC: Support sending Variants over IPC

Browse source 
The format is quite simply the type index followed by the type in its
own native encoding; just implementing the receive side with static
typing is a bit convoluted. The only limitation of this implementation
is that the variant type has to contain an Empty somewhere as it is not
default constructible otherwise.
