Cédric Pasteur b4419a6760 Better deal with memory less nodes
There are now 3 kinds of nodes: Eprim : primitive 
nodes, Enode: nodes with memory, Efun: nodes 
without memory.

Typing now sets correct eq_statefull and b_statefull
for equations and blocks. Resets are only added 
when a node with memory is called.

The calling convention is the generated code needs
to be modified so that we can remove the context 
for nodes without memory.
