Fixed prior bounds (according to the doc in master branch).
...
* Second and third positional arguments after the name of the
estimated parameter in the estimated_params block are only
considered in the optimization stage (not in the MCMC)
* Do not store bounds in bayestopt_, because bounds do not always
reflect restrictions implied by prior shapes.
* prior_bounds routine returns a structure (with fields lb and ub)
instead of a matrix.

Fix several bugs related to estimated measurement errors
...
1. The first call to set_prior overwrote the first column of
estim_params_.var_endo storing the position of the variable with
measurement error in M_.endo_names with the position in
options_.var_obs. All subsequent calls to set_prior then lead to
crashes.
2. At the same time, for correlations of ME, the first column of
estim_params_.corrn still stored the position of the variable with
measurement error in M_.endo_names. But subsequent calls to it were done
as if it stored the position in options_.var_obs
I introduced two new variables in estim_params_ storing the respective
positions in var_obs so as to not necessitate changes in the
preprocessors.
3. For cases of calibrated measurement error correlations, the
covariance matrix was not updated.
4. Fixing a lot of smaller bugs related to measurement errors, including
some copy and paste errors

Efficiency & Cosmetic changes related to the design of bayestopt_ and
...
the computation of the prior density.
bayestopt_.p1 is always the prior mean
bayestopt_.p2 is always the prior standard deviation
bayestopt_.p3 is unchanged
bayestopt_.p4 is unchanged
bayestopt_.p5 [new field] is the prior mode
bayestopt_.p6 [new field] is the first hyper-parameter of the prior density
bayestopt_.p7 [new field] is the second hyper-parameter of the prior density
These fields are defined in set_prior and are never changed after. In
the previous version of Dynare, the hyper parameters of the densities
were updated at each iteration of the optimization routine or the
metropolis.
Removed fields pmean and pstdev.
Vectorized the code in priordens.
Fixed the bug mentionned by Gianni. If a (logged) density is evaluated
outside the prior domain, the output of priordens if minus infinity
(instead of a complex number).
