- fix a problem returning the covariance matrix when fit failed. Now all minimizer implements CovMatrixStatus() when they calculate the covariance matrix. Add in FitResult method to return covariance matrix status
- Add a flag in interface of Minimizer::GetMinosError to do separatly positive or negative errors
- fix usage of default minimizer from what is defined in etc/system.rootrc
- improve comment in TH1::Fit and TGraph::Fit for usage of TFitResultPtr

import changes from math development branches for subdirectory math. List of changes in detail:
mathcore:
---------
MinimizerOptions:
new class for storing Minimizer option, with static default values that can be
changed by the user
FitConfig:
- use default values from MinimizerOption class
- rename method to create parameter settings from a function
FitUtil.cxx:
improve the derivative calculations used in the effective chi2 and in Fumili and
fix a bug for evaluation of likelihood or chi2 terms.
In EvaluatePdf() work and return the log of the pdf.
FitResult:
- improve the class by adding extra information like, num. of free parameters,
minimizer status, global correlation coefficients, information about fixed
and bound parameters.
- add method for getting fit confidence intervals
- improve print method
DataRange:
add method SetRange to distinguish from AddRange. SetRange deletes the existing
ranges.
ParamsSettings: make few methods const
FCN functions (Chi2FCN, LogLikelihoodFCN, etc..)
move some common methods and data members in base class (FitMethodFunction)
RootFinder: add template Solve() for any callable function.
mathmore:
--------
minimizer classes: fill status information
GSLNLSMinimizer: return error and covariance matrix
minuit2:
-------
Minuit2Minimizer: fill status information
DavidonErrorUpdator: check that delgam or gvg are not zero ( can happen when dg = 0)
FumiliFCNAdapter: work on the log of pdf
minuit:
-------
TLinearMinimizer: add support for robust fitting
TMinuitMinimizer: fill status information and fix a bug in filling the correlation matrix.
fumili:
------
add TFumiliMinimizer:
wrapper class for TFumili using Minimizer interface

- sync changes of David from dev. branch
use directly ROOT::Math::IMultiGenFunction and ROOT::Math::IMultiGradFunction instead of typedef's

Diff to
previous 22352
- fix coding convention violations (mainly change name of RootFinder enumeration)
- fix warning observed on the Windows nightly (avid generating the dictionary for fit method functions for all platforms, it is not needed)
- add implementation of Minimizer interface using TMinuit and the linear fitter
- add method SetBasisFunctions in TLinearFitter class to set the linear terms
- add some optimization of wrapped functions and improve doc
