- merge classes from math (TMath, TComplex and TRandom) in libMathCore
- change various functions of TMath (work from David ):
	- make a single template functions for all the various types (like Sort or Binart Search) 
        - use std implementations for Sort, BinarySearch, LocMin
        - use mathcore special functions for Gamma and Beta functions 

- remove genvector from mathcore
- add classes for integration, derivation and root findings using the algorithms of TF1
-  use the plug-in manager to instantiates different implementations of the same classes in MathMore

ROOT can not be compiled with gcc-4.3.
Some ROOT source files doesn't contain required #include directives,
for example, they use strlen(), but #include <string.h> is missed or
malloc() is used and #include <stdlib.h> is missed. 

Earlier versions of gcc allowed some headers to be included implicitly,
but issued a warning (-Wimplicit-function-declaration). Newer one,
gcc-4.3 denies such silly behaviour: all required headers must be explicitly
included. 

Attached patch fixes this. Also it fixes another issue, which disallows
ROOT to compile under gcc-4.3: C functions don't belong to namespace std,
so expressions like std::memcpy() are no longer valid and plain memcpy()
should be used instead.

this patch prevents all dictionaries from being rebuild when non dict related
changes are made in CINT. When the dictionaries change the new
cint/inc/cintdictversion.h must be updated which triggers a dictionary
rebuild. For example:
touch cint/src/v6_var.cxx && make: rebuild no dictionaries
touch cint/inc/cintdictversion.h && make: rebuild all dictionaries
touch utils/src/rootcint.cxx && make: rebuild all dictionaries

* fix error calculation, now similar to TH1 etc
* allow for non-equal bin sizes: call constructor without bin edges,
call SetBinEdges() afterwards

//
//  Method Improvement by Jason A Detwiler (JADetwiler@lbl.gov)
//  -----------------------------------------------------------
//   The nuts-and-bolts of the TMath::KolmogorovTest() algorithm is a for-loop
//   over the two sorted arrays a and b representing empirical distribution
//   functions. The for-loop handles 3 cases: when the next points to be 
//   evaluated satisfy a>b, a<b, or a=b:
//    
//      for (Int_t i=0;i<na+nb;i++) {
//         if (a[ia-1] < b[ib-1]) {
//            rdiff -= sa;
//            ia++;
//            if (ia > na) {ok = kTRUE; break;}
//         } else if (a[ia-1] > b[ib-1]) {
//            rdiff += sb;
//            ib++;
//            if (ib > nb) {ok = kTRUE; break;}
//         } else {
//            rdiff += sb - sa;
//            ia++;
//            ib++;
//            if (ia > na) {ok = kTRUE; break;}
//            if (ib > nb) {ok = kTRUE; break;}
//        }
//         rdmax = TMath::Max(rdmax,TMath::Abs(rdiff));
//      }
//    
//   For the last case, a=b, the algorithm advances each array by one index in an
//   attempt to move through the equality. However, this is incorrect when one or
//   the other of a or b (or both) have a repeated value, call it x. For the KS
//   statistic to be computed properly, rdiff needs to be calculated after all of
//   the a and b at x have been tallied (this is due to the definition of the
//   empirical distribution function; another way to convince yourself that the
//   old CERNLIB method is wrong is that it implies that the function defined as the
//   difference between a and b is multi-valued at x -- besides being ugly, this
//   would invalidate Kolmogorov's theorem).
//    
//   The solution is to just add while-loops into the equality-case handling to
//   perform the tally:
//    
//         } else {
//            double x = a[ia-1];
//            while(a[ia-1] == x && ia <= na) {
//              rdiff -= sa;
//              ia++;
//            }
//            while(b[ib-1] == x && ib <= nb) {
//              rdiff += sb;
//              ib++;
//            }
//            if (ia > na) {ok = kTRUE; break;}
//            if (ib > nb) {ok = kTRUE; break;}
//         }

 - math:      remove the const in ParamFunctor::operator()(double *x, double *p)
  
 - mathcore:     
              - improve integration interface, have now two separate classes : 
              one for 1D the other for multi-dim functions. Rename class IntegratorMultiDim to AdaptiveIntegratorMultiDim
             - clean up of IFunction by removing the un-necessary Dim template parameter
             - add from Cephes inverse functions for normal, beta and gamma functions 
             - improve error reporting

 - mathmore: improve simulated annealing class and ad a test program taken from GSL: simanTSP
             fix problem with dictionary of concrete function classes (like Polynomial) on Windows
