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so expressions like std::memcpy() are no longer valid and plain memcpy()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

1. While name of the class is changed, one should use TDirectoryFile class instead of
   TDirectory at the moment, then new directory object is created.
2. Appropriate change done in non-binary part of TDirectoryFile::Streamer() that old version of
   class can be read.

This is the continuation of the effort to structure libCore into
independent sub-packages.

A new class TDirectoryFile is introduced. It derives from TDirectory
and takes from TDirectory all the I/O functions.

All the classes (except TROOT) deriving from TDirectory are now derived
from TDirectoryFile. TDirectory keeps the previous API for back compatibility
with several functions made virtual.

This change should be back compatible, except if the user codes creates
a file sub-directory by direct invokation of the TDirectory constructor
instead of calling TDirectory::mkdir.

Note that TMapFile is not yet fully adapted to the new scheme.

CVs been changed into a pure abstract interface.
The concrete implementation is in the new class TBufferFile.
All classes previously deriving from TBuffer derive now from TBufferFile, ie

  TBuffer  <- TBufferFile  <- TMessage
                           <- TBufferXML
                           <- TBufferSQL
                           <- TBufferSQL2

Because there are several problems with C++ operators overloading,
The I/O operators are defined in TBuffer. These are inline functions
calling C++ virtual functions defined in TBuffer and overloaded
by TBufferFile and all other derived classes when necessary.

The previous implementation of TBuffer.h included <vector> and Bytes.h.
The two include statements have been moved to TBufferFile.h. As a result the
compilation of the ROOT system is now slightly faster and a big bonus
is that changes in TBufferFile or Bytes.h will affect only TBufferFile
and will not force the recompilation of the entire system.
This change has some side-effects. If you assumed that include <vector>
was done by TBuffer.h, you may have to specify this include directly
in your class. This was the case for a few ROOT classes.

   TMath::Abs, TMath::Min, TMath::Max, TMath::Sign, TMath::Range
These functions are unfortunately not defined in a standard way in std::

This include is referenced by a new version of TMath.h.
As a result, TMath.h is back compatible with the previous version.

TMathBase.h is used in place of TMath.h in all the classes
that will go into the future miniCore library.
TMath.h and the TMath implementation will go into a new math sub-directory.

TString.h uses TMathBase.h instead of TMath.h.
As a result, it was necessary to include "TMath.h" in some classes
assuming that TMath was included via TString and using other functions
than the ones defined in TMathBase.h

-Rename class TFilePrefetch -> TFileCacheRead
-Rename class TTreeFilePrefetch -> TTreeCache
-Add new class TFileCacheWrite that implements automatic caching
 when writing network files. This class replaces the previous class TCache.
-old TCache class deleted.
-TFileCacheRead can read buffers from the wite cache in TFileCacheWrite.
-As a result TFile::UseCache is obsolete. The function is kept for
  backward compatibility.
-Remove references to TCache from TXMLFile, TSQLFile, TwebFile, TNetFile
-remove pointer TFile::fCache
-Add pointers TFile::fCacheRead and TFile::fCacheWrite
-Remove members fMaxCacheSize and fPageSize from TChain

  rm -f base/src/*.d base/src/*.o
  rm -f net/src/*.d  net/src/*.o

2. Small fix in TSQLFile. With old MySQL versions it does not try to use TSQLStatement class.
3. Enabling/disabling error output for TSQLStatement class.
4. Fix in error handling in TMySQLServer::Statement() method. Previousely error code was not correctly stored.

Dictionary G__%.o: G__%.cxx rules now in main Makefile instead of Module.mk's
=> changes in Module.mk.

First Module.mk's included, then Makefile.precomp - we need ALLHDRS defined

Split $(PCHEXTRAOBJ) and $(PCHFILE) rules - fixes clash with make -j2

Define CINTCXXFLAGS:= - otherwise they will contain PCHCXXFLAGS via
their definition as a copy of CXXFLAGS.
