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 with dev brunch (r=24397):
- use std::string for parameter name and remove un-necessary limitation on the length of parameter name
maintan the Name() method returning a char * (for backward compatibility) and add a new method GetName() returning
a reference to a std::string
- add also a method in MInuit2Minimizer to get correlation coefficient between parameter i and j and a method to get
the global Correlation coefficient of parameter i
- add new complex tests of fitting used for parallelization studies
- compile in ROOT also the tests in MnSim and MnTutorial

- syncronize mathcore, mathmore, minuit2 and test/stressMathCore with development branches
- main changes are:
- move some remaining pdf (like beta and landau) from mathmore to mathcore
- add missing landau_cdf
- fix a precision error with normal_cdf (and normal_cdf_c) for small x (large x). Use the correct erf or erfc function according to x
- move majority of quantiles functions from mathmore to mathcore ( implementation is based on inverse functions from Cephes, implemented in SpecFuncCephesInv.cxx)
- add method to create Minimizer concreate classes via the plugin manager
- add possibility to use multi-dim funciton type in one dim integration
- minuit2: add some missing include cassert
