      Dictionary G__%.o: G__%.cxx rules now in main Makefile instead of Module.mk's
=> changes in Module.mk.

First Module.mk's included, then Makefile.precomp - we need ALLHDRS defined

Split $(PCHEXTRAOBJ) and $(PCHFILE) rules - fixes clash with make -j2

Define CINTCXXFLAGS:= - otherwise they will contain PCHCXXFLAGS via
their definition as a copy of CXXFLAGS.

MSVC: prevent LNK4206 linker warning (-Yl...)

      handle in a consistent way the new rootcint options -cint (default),
-reflex and -gccxml. The type of dictionary to be used can be specified
like: ./configure --with-dicttype=reflex. Notice that this option is
there only for the developers working on the migration to the new
dictionary system.

      in case we have gmake >= 3.80 we can use the new | (order) syntax where
all dependencies after the | are required to be there but not trigger
execution of the rule. This should greatly enhance the build experience
on Win32 and AIX (platforms that need the EXPLICITLINK option).

      Implement a cache facility in TVirtualFitter. · 8440e981
      Rene Brun authored 
      The class has a new function TVirtualFitter::SetCache that creates
an internal structure where the information about histogram bins
is stored (bin position, size, content and error).
The cache is used during fitting and speeds up (factor 2) TH1::Fit
when called with the default TMinuit. Only the points included in
the fit are stored in the cache.

Currently the cache is set and filled only in TH1::Fit.

The TFitter and TFumili classes have been changed to take into account
the information in the cache.

The free functions called by Minuit have been rewritten.
They are now only an interface calling the fitter member functions.

- improved comments for TGraph::Fit and TFitter::GraphFitChisquare for this

      - TLinearFitter class: Linear fitter is used to fit a set of data points with a linear
  combination of specified functions (with or without weights). The "linear" in the name
  stands for "linear in parameters", not variables. The main advantages,
  compared to a general non-linear fitter, is that the linear fitter is considerably
  faster and doesn't require setting the initial values of parameters.
  The linear fitter can be used directly or through TH1::Fit and TGraph::Fit functions
  When it's used directly, functions of more than 3 dimensions can be fitted.

- TFormula: a new data member fLinearParts and methods to process it are added. Now
  one can create a function of the type that can be fit by the linear fitter.
  Example: TFormula f("f", "x++sin(x)") is equivalent to
  TFormula f("f","[0]*x + [1]*sin(x)"), but if a TH1::Fit or a TGraph::Fit is performed
  with the 1st formula, it goes through the linear fitter, if it's performed with the
  2nd formula, it goes through Minuit.

- TMultiGraph class: the Fit method is implemented, allowing to fit all the graphs
  of a multigraph simultaneously

- TGraph, TGraphErrors, TGraphAsymmErrors, TGraphBentErrors - functions GetEXhigh(),
  GetEXlow(), GetEYhigh(), GetEYlow() implemented to simplify the GraphFitChisquare()
  function of the TFitter class

- TH1, TGraph, TGraph2D, TMultiGraph - changes in the Fit functions, allowing to use
  the linear fitter. Fitting with "polN" functions redirected to use the linear fitter,
  in cases where no options, except "range", are specified.

 Int_t     GetStats(Double_t &amin, Double_t &edm, Double_t &errdef, Int_t &nvpar, Int_t &nparx) const  = 0;

Add a new function
 Double_t  GetCovarianceMatrixElement(Int_t i, Int_t j) const;

Similar changes in TFitter and TFumili.
