2f2044e74b gf : imfreq : clean evaluator on int
- evaluator on int was not using the same algorithm
as matsubara_freq, which can be surprising...

05c717e70f gf: imfreq : fix evaluator for n<0
- in positive only case, the evaluator for n<0
was wrong : must shift the integer by -1 for the fermions.

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)
mesh_pt should NOT be done directly by (),
it should be casted to matsubara_freq.
Removed an old line of code which we forgot to clean
when introducing matsubara_freq

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 ?

da7e7ec971 Fixed fit_tail for pos. and neg. matsub + bosonic

7aedaef945 arrays : fix matrix = scalar for complex types
Pb :
M() = rhs; // rhs of type RHS
Currenlty does :
M(i,j) = (i==j ? rhs : RHS{})
Changed to
M(i,j) = (i==j ? rhs : RHS{0*rhs})

If RHS is a double, int ... Same result.
If RHS is a matrix, gf, currently the offdiag elements
are default constructed (i.e. of 0 size !).
Which can break operations later (matrix<matrix<double>>)
After change : all elements have the same size !
