Import the code from the branch dev/datamodelevolution revision 25436

This implements the infrastructure for the new Data Model Evolution Scheme.

This Data Model Evolution is brought to your courtesy of BNL/STAR/ATLAS/Fermi/Cern

Current Capabilities:
  Assign values to transient data members
  Rename classes
  Rename data members
  Change the shape of the data structures or convert one class structure to another
  Change the meaning of data members
  Ability to access the TBuffer directly when needed
  Ensure that the objects in collections are handled in the same way as the ones stored separately
  Supported in object-wise, member-wise and split modes.

Coming soon:
  Make things operational also in bare ROOT mode
  Ability to transform data before writing
  Support for changing the class type of nested object in a split branch
  Support for access to onfile version of nested objects from within the parent rule

LinkDef rule syntax:
  Setting a transient member:

#pragma read sourceClass="ACache" targetClass="ACache" source="" version="[1-]" target="zcalc" \
   code="{ zcalc = false; }"

  Setting a new member from 2 removed members

#pragma read sourceClass="ACache" targetClass="ACache" source="int x; int y; char c"  version="[8]" target="z" \
   code="{ z = onfile.x*1000 + onfile.y*10; }"

   Renaming a class

#pragma read sourceClass="ACache" version="[8]" targetClass="Axis" \
   source="int x; int y;"  target="z" \
   code="{ z = onfile.x*1000 + onfile.y*
#pragma read sourceClass="ACache" version="[9]" targetClass="Axis";

Selection XML syntax

  <read  sourceClass="ACache" targetClass="ACache" source="" version="[1-]" target="zcalc">
  <![CDATA[
   { zcalc = false; }
  ]]></read>

embed the Cache allocation and deallocation in TStreamerInfo::ReadBuffer (StreamerElement type: kCacheNew and kCacheDelete).  The Cache stack is now a stack of TVirtualArray pointer.
