- remove the dirty vpath hack
- factorize between the two estimation DLLs
- factorize within SWZ makefile

* added dynare_simul_ DLL
* factorized in a library object the Dynare++ code shared between gensylv, k_order_perturbation and dynare_simul_

Build system: refactored the build system for MEX files, using two sub-packages with their own configure scripts

* Simplified the way we deal with various Octave/MATLAB contexts from MEX files:
  - only three defines: MATLAB_MEX_FILE, MATLAB_VERSION (hex number) and OCTAVE_MEX_FILE
  - one header for MEX files: dynmex.h
  - headers for BLAS and LAPACK: dynblas.h and dynlapack.h (used from Dynare++ and the MEX files)
* Merged the two sources trees of sylvester library

Note that dynare++ will only be built if configure finds ctangle, blas, lapack and pthreads
