Fix a problem reported by Bill Tanembaum.
The problem had to do with nested typedef to simple type.
I simplify the resulting code of the shadow class by resolving the
typedef to their true names.

The following patch makes sure that the Shadow Class always use fully qualified name when refering to their data members.  This is avoid a confusion when the template
parameter and the template instantiation are in the same dictionary.  (This is usefull for CMS).

This patch:
        a) add ClassDef to the generate TSelector with version 0.
        b) keep the Error message for all cases but those inheriting from TSelector
                (Warnings are not seems in the default rootcint mode).
        c) rootcint succeed in all cases (hence allowing user to compile
                classes that do not strictly implement the TObject interface).

The following patch 'upgrades' the new TClass and TGenericClassInfo code to actually follow the ROOT coding
conventions.

This patch also enables a rootcint error (prevents the creation of the dictionary) in the case where the class
derives (directly or indirectly) from TObject and do not have its own ClassDef.

3 helper class in ROOT failed the test: TGFrameElement, TAssoc and TGMenuEntry.

constructors and destructor.  It also allows for feeding a way to access
the constructor and destructor independently of the dictionary.

5 new data members were added to TGenericClassInfo/TClass.
Those are direct wrapper around
        - default constructor
        - array constructor
        - delete
        - delete []
        - destructor

In TKey::TKey and TBuffer::WriteObjectAny, a new message was added:

Warning in <TKey::TKey>: Since TSocket had no public constructor
        which can be called without argument, TSocket objects can not be read
        with the current library. You would need to add a default constructor
        before attempting to read.

This patch adds the ability to save objects of classes using multiple
inheritance (directly or indirectly) as part of other objects.
(Previously multiple inheritance was only supported for top level objects).

In TBuffer.h, TBuffer.cxx:

   TBuffer::WriteObject( const void *actualObjStart, TClass *actualClass);

has been made protected. It is replaced by

    WriteObjectAny(const void *obj, TClass *ptrClass);

which has a slightly different semantic (for multiple inheriting classes).
The value of 'obj' in expected to be a value that can be legally stored
in a pointer to an object of the type described by 'ptrClass'.  I.e:
    MyClass *ptr;
    ....
    b.WriteObjectAny(ptr,gROOT->GetClass(typeid(MyClass)));

We introduced:

   void    *ReadObjectAny(const TClass* cast);

which returns a value suitable to be stored in a pointer to an object of
the type described by 'cast'.  I.e, a typical usage is:
   MyClass *ptr = (MyClass*)b.ReadObjectAny(MyClass::Class());

The existing function

    TObject *TBuffer::ReadObject(const TClass *clReq)

now ignores its parameter and returns the address where the object read
actually start.  It should be noted that if the object is of a class
which derives from TObject but not as a first inheritance, this value is
NOT a valid TObject*.  We recommend using ReadObjectAny instead.

In TKey.cxx, I reverted the comments to properly describe how to deal with
top level object which inherits from TObject but not as a first inheritance
(can not use dynamic_cast).

In TGenericInfo.h, TGenericInfo.cxx, rootcint.cxx and TClass.cxx, we moved
to always use an IsA wrapper function instead of using the interpreter for
TObjects.

TClass.cxx has been modified to optimize a few function now called many
times.

TStreamerInfo.cxx and TStreamerElement.cxx has been modified to use the
new TBuffer function and to properly read/write multiple inheriting objects.

"I think it is inconvenient for the user (and the documenter) that the
'cint' executable behaves differently in the ROOT environment or in the
pure CINT environment.  For example, the lastest change broke Fons'
script to build the cintdlls (since linG__set_globalcompk was off by
default, the cintdlls where actually empty!).

So I propose to reset the 'link mode' to be on by default for the 'cint'
executable.  We can then explicitly set it to be off in the 'rootcint'
executable.

In order to properly implement this, I also needed to fix the handling
of the argument to '-c' (corretly use the abs value and propagate all
the change into G__set_globalcomp.

This updates increase the support for const data members (the existing
std::string special cases needed to be updated).  It also explicitly
disable I/O for data members which are references.

Rather than modify the current behavior of the TClass constructors, I decided to add some code to the generic
showmember to avoid constructing the TClass object if the corresponding that is not present AND the data member is

instead of, e.g. base/inc. This was due to the search path being -Iinclude
and not -Ibase/inc (this special seach path is only used in rootcint_tmp
used to build ROOT's own dictionaries). Also reorder two linkdef files to
avoid search for not yet loaded classes.

Also some reformatting of recently introduced non-coding style conforming code.
