* [vasp] read fermi from vasp h5 archive and write deltaN to vasp h5 archive
* Reading vasptriqs.h5 file; reading GAMMA file for non-collinear full csc
* fix read error for tetrahedron data and eigs properties
* write deltaN only to vasp h5 if present, write to GAMMA text file only for old interface
* support symmetries at DFT level in VASP
* use IBZ kpoint list for writing GAMMA vaspgamma.h5
* make vaspgamma.h5 default
* write n_k_ibz into dft_misc_input so in can be used inside of sumk
* add new svo converter test

* moved the plovasp C++ code to c++/triqs_dft_tools/converters/vasp
* added global header triqs_dft_tools/triqs_dft_tools.hpp
* python dir based on single cmakelist file
* registered C++ tests for plovasp
* corrected imports for py3 tests for plovasp
* corrected block order in sigma_from_file and srvo3_Gloc
* exchanged ref files for sigma_from_file, srvo3_Gloc, SrVO3.ref.h5
* moved vasp converter bash scripts from dir shells to bin dir
