0a1285405c [gfs] Lattice fourier, multivar G, curry, tail
- Add Fourier for lattice.
  - Add regular_bz_mesh, cyclic_lattice, and their FFT.

- rm freq_infty.
- The gf can now be evaluated on a tail_view, which result in composing the tail.
- Fix the following issue :
  g(om_) << g(om_ +1)
  will recompose the tail correctly.
- TODO : TEST THIS NEW FEATURE IN DETAIL.

- Work on singularity for G(x, omega)

 - Separate the factory for singularity from the data factory in gf.
 - overload assign_from_functoin (renamed).
 - Fix singularity_t and co in the gf (const issue).

- Clean tail, add tail_const_view
 - add m_tail for x -> tail on any mesh
 - test curry + fourier works on k

4af1afbdaf hdf5 : clean up
- For users : only change is :
   H5::H5File in apps. to be replaced by triqs::h5::file, same API.

- using only the C API because :
   - it is cleaner, better documented, more examples.
   - it is the native hdf5 interface.
   - simplify the installation e.g. on mac. Indeed, hdf5 is
     usually installed without C++ interface, which is optional.
     E.g. EPD et al., brew by default.
     Also the infamous mpi+ hdf5_cpp bug, for which we have no clean solution.

- clean the notion of parent of a group. Not needed, better iterate function in C LT API.
- modified doc : no need for C++ bindings any more.
- modified cmake to avoid requiring CPP bindings.
