"sometimes I get floating point exception in setting rms in H1InitGaus.
Due to precision calculated rms becomes < 0 ( -1e-20 in my case).
This patch fixes the problem.

I had introduced an unitialized variable with my previous patch. I attached the
fix.
In attachment there is also a fix for unions having a common exit boundary - infinite
loop in TGeoUnion::DistToOutside().

1) In normal TBasket constructor mother directory assigned to TBranch directory.
2) In TBasket::CopyTo method file for copy is used directly without setting gFile/gDirectory
3) In TBasket::WriteBuffer mother dir assigned once again. It is required when basket with
   default constructor was created.

Several small changes to exclude using of gDirectory and correct initialisations.

1) New fMotherDir memeber was added to indicate to which directory and file (via dir->GetFile()) key belongs to.
   Mother directory must be specified in constructor, therefore all consructors get additional argument - mother
   directory
2) New method Build() was added to initialize members of TKey class. It is called from every constructor of
   TKey class.
3) Everywhere gFile and gDirectory were replaced by GetMotherDir() & GetFile(). Two methods: TKey::WriteFile()
   and TKey::Create() gets new argument - TFile* f, indicating which file should be used. By default,
   file from mother directory is used, but for some cases in tree other file pointer specified directly.
4) In TKey::ReadBuffer() sometimes key will be added to gDirectory. For normal cases it should not happen,
   therefore I extract main code to TKey::ReadKeyBuffer() and call it from the places where I know no
   any gDirectory->AppendKey should be called. For instance, when you store streamerinfos. Functionality of
   TKey::ReadBuffer() was not changed. Actually, I did not found a situation, when this function called
   and code with gDirectory->AppendKey() is activated (I check with stress and roottest).

1) In normal constructor I add new argument - mother of directory.
   If it is not specified (for instance, if user creates TDirectory himself), gDirectory will be used.
   In principle, fMother was before, but now it consecutively used in most TDirecory methods, related to
   parent/child relationship.
2) Together with directory fMother member file pointer fFile propogated to all childs.
   Consequently, each directory knows to which file it belongs.
3) When streamed from the file, fFile memeber is assigned from TBuffer::GetParent(). fFile is enougth
   to read keys from the file. Mother directory is assigned later in TKey::ReadObj().

In TDirectory::ReadAll() cast to TNamed was used to find and delete existing object,
   but some TObject also can return correct names (like TCanvas).

TDirectory::GetPath() uses static variable and will fails in multithread application.
   I introduce new GetPath() method and TString fPathBuffer to produce correct full path.
   Old code was moved in GetPathStatic() method. To optimize memory usage, one can replace TString
   by const char* (as it was before).

3 new virtual methods:
   virtual void TBuffer::ClassBegin(const TClass*, Version_t = -1) {}
   virtual void TBuffer::ClassEnd(const TClass*) {}
   virtual void TBuffer::ClassMember(const char*, const char*, Int_t = -1, Int_t = -1, Int_t = -1) {}
This method can be use to make a custom streamed object 'splitable'

Add a new Bit for TBuffer kTextBasedStreaming which can be used in the
streamer to facilitate writing to a text output (xml, sql).

- TEnv::SetValue crashes if TEnv was created with default constructor
- Implement TEnv::GetRcName
- Set TEnv streamable (Class version set to 1 instead of 0)
- Set TEnvRec streamable (Class version set to 1) no ClassDef before
- Add a public default constructor to TEncRec
- Fix typo in TEnv::GetValue

In TBasket::Streamer a new TBuffer is created.  Now we use the current buffer's
parent instead of gDirectory to set the new buffer's parent.

   TBasket was created but not used and lost.
TBasket::CopyTo (line 135). Member fHeaderOnly set to kTRUE twice. I think,
   second time after basket streaming should be fHeaderOnly = kFALSE.
Thanks Sergei for pointing those out.

   Inherit from DoubleSlider widgets and allow easy
   selection of a min, max and pointer value out of
   a range. The pointer position can be constrained
   to edges of slider and / or can be relative to
   the slider position.

 - modification of slider1h.xpm and slider1v.xpm for
   a better design.

   of these new sliders.

From Axel:
- fix for  a problem with rootcint
segv'ing on fopen(0, "r") if the linkdef.h can't be located.

From Stefan:
- removes the printout in case of rootcint -gccxml
- removes the shadow class generation for rootcint -gccxml. Shadow
  classes should now only be generated with rootcint -cint
