Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.
