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.

- old boost includes before C++11
- remove boost serialization, make macro TRIQS_MAKE_NVP temporarely
- remove boost::is_complex (can be written in 2 lines...)
- move some lib in cpp

2f2044e74b gf : imfreq : clean evaluator on int

5128126055 arrays: change operator() && for const_view
Changed operator()(int, int...) && for array, and views.

- For const_view and regular type, returns value_type (i.e. a copy).
  NB : does make a copy, not a move. Ok for scalar type. TODO: think for complicated types.
  This allows codes like :
  f(x)(0,0) where f : x-> matrix or const_view
  to be correct in clef expression evaluation.

- For _view : return a value_type &, as before to allow :
    A(....)(0,0) = rhs;
  It is not possible to detect dangling refs in that case at compile time.
  Added a security in TRIQS_ARRAYS_DEBUG mode to detect a dangling ref at run time,
  i.e. the case where the view is "unique" (ref count ==1).
  This would be a quite bad design anyway ...

- also :

 - clean operator[] for vector (old workaround for old gcc...)
 - add IsView flag in ISP impl class, for the impl. of operator() &&

a1a29d6c85 gf: correct evaluator for gf imfreq (remove mesh_pt)

b8d7373177 arrays : fix auto_assign for chains assignment.
A(i_)(om_) << ...
for A an array of gf was not working.
Modified the auto_assign of arrays to handle the case when the object
in the array is itself autoassigned.
Using the model of std::vector adapter for clef, which works.
Also fixed the gf for a little details (gf_impl is usually in the expression tree, not gf).

73d81cc55a gf: correct bug in matsubara_freq mesh point
- bool at_end() for a mesh point means AFTER the last point ,
as end in STL. It was not correct ( +1 missing).
- also the at_end was not computed in the mesh product.
- it slightly changes the test_fit_tail --> just changed the output.
--> did this bug affect other functions/codes ?
