Incidentally, this makes it possible to use model-local variables with either
the “block” or “bytecode” option. (Ref: dynare#1243)

This brings those models in line with stochastic models.

However note that transformation is still not exactly the same on stochastic
and deterministic models, because there is no need to take into account the
Jensen inequality on the latter. In deterministic models, there is a one-to-one
mapping between exogenous with lead/lags and auxiliaries, while in stochastic
models, an auxiliary endo may correspond to a more complex nonlinear expression.

TODO: Check that we can do the same in the matlab version…

Introduce a new method for decomposing a product of factors, so that we can
identify expressions of the form (1-optim_share)*A*B.

Also enforce that the optim_share parameter be in a factor of the form
1-optim_share (previously it would accept any expression containing the
parameter).

Note that this fix does not yet allow to actually write non-optimizing parts of
the form (1-optim_share)*A*B, since at a later point the preprocessor imposes
that this part be a linear combination of variables (but in the future we could
think of expanding the A*B product into a linear combination if, for example, A
is a paramater or a constant and B is a linear combination).

– Fix order of items in this structure. Previously, items were ordered
  according to the declaration order of parameters. Now, items are order
  according to lag order (first lag appears first)
– Gracefully handle the case where there is no autoregressive part

Replace it by calls to ExprNode::collectVariables() at the single place where
it was used.

Many recursive function on ExprNodes were not correctly recursing into the
definition of model local variables.

SymbolTable::getTypeSpecificID() now throws an exception instead of returning -1 when symbol does not have a type-specific ID

This can potentially avoid some undetected bugs.

Value passed to steady_state_growth was not acknowledge.

Closes: #53

This greatly facilitates the job of the compiler during the optimization pass,
since we promise that the various pointers do not overlap each other. It may
now be possible to reenable some of the optimization flags that were disabled
without sacrificing compilation time, but this needs more investigation.
