 - CMake configuration changes to build Gaudi with optional externals missing

   In the last days I experimented a bit with teaching Gaudi how to build when
   only ROOT, Boost and TBB are available to it. This is the result. As far as I
   can tell the code builds in the same way as the current master branch when
   all possible externals are available. (All the ones available in a full ATLAS
   offline build at least.) And I'm also able to build the project in these
   modes:
     * On Ubuntu 16.04 with the system provided Boost and TBB versions, against
   a privately built ROOT 6 version.
     * On macOS Sierra against privately built Boost, ROOT and TBB versions.
   Both when building the project completely on its own, and when building it
   against an ATLAS externals project.
    Some notes:
     * The code uses C++14 expressions in quite a few places by now. So I raised
   the default C++ standard to C++14. This is the default in ATLAS builds since
   a while, I only saw this as an issue when building Gaudi "on its own" with a
   very minimal configuration command.
     * While the code advertises that it still has support for ROOT 5, it's not
   able to build against it since a wile. Since the updates I put in for TLS
   variables on macOS. (The macros used there are ROOT 6 only.) And this update
   makes things even worse. As the code now relies on not providing the
   definition of some classes to the dictionary generator in GaudiPython that
   are not available. (Because AIDA or XercesC is missing.) While ROOT 6 handles
   this with just a build warning, ROOT 5's genreflex treats this with an ERROR
   message. That I was unable to get rid of.
    So, extended testing is clearly necessary, the configuration code could
   definitely be fine tuned as I probably turned off the build of more source
   files than absolutely necessary, but I think we should move ahead with such a
   configuration organisation.

================================ Gaudi v28r0 =================================

! 2016-10-27 - Gerhard Raven, Marco Clemencic (commit b111898)

 - modernization of Property

   This is a major rewrite of the system of `Property` classes. Started as  the
   implementation of GAUDI-1214, it continued as a review of
   `IProperty` and `PropertyMgr`, to end up in a complete rewrite
   (and optimization) of `PropertyWithValue`.

   * Fixes GAUDI-1214
    - added missing `declareProperty` signature
    - added `PropertyHolder` (an updated `PropertyMgr`)
    - adapted all properties in Gaudi
   * improved use of `PropertyHolder`
    - use inheritance instead of composition
    - removed ~200 (duplicated) lines of code in GaudiKernel
   * optimization of Property (fixes GAUDI-1229)
    - use templates and automatic code generation to handle efficiently
      both value and reference properties
      - avoid creation of values on the heap (see GAUDI-1229)
      - removed the *owned* boolean flag
      - improved usability of properties (e.g. begin/end wrappers for
        C++11 loops, increment/decrement operators...)
      - deprecated use of C arrays as properties
    - merged features of `PropertyWithVerifier`, `SimpleProperty` and
      `SimplePropertyRef` into `PropertyWithValue`
    - deduplication of name and doc strings via

   [`boost::string_ref`](http://www.boost.org/doc/libs/1_61_0/libs/utility/doc/html/string_ref.html)

      and a static storage  (see GAUDI-1229)
   * Fixes GAUDI-1205
   * add deprecation warnings in service accessors of `Algorithm` (@graven)
   * renamed `Property` base class to `Gaudi::Details::PropertyBase` and
   `PropertyWithValue` to `Gaudi::Property`
    - added backward compatibility type aliases (but not compatible with
      forward declarations of `class Property`, which should be replaced
      by `#include "GaudiKernel/PropertyFwd.h"`)
   * added macro `GAUDI_PROPERTY_v2` to allow easy implementation of
    backward compatible changes in derived projects (e.g. when user code
    relied on `DoubleProperty` having a verifier)
   * Fixes GAUDI-1268
    The changes are as backward compatible as much as possible (except if you
   explicitly inherit from `SimpleProperty`, or you forward declared
   `class Property`, which now are typedefs), but must be validated in the
   experiment frameworks.

! 2016-03-11 - commit 4912fc9

 - Merge branch 'GAUDI-1099' into 'master'

   fix GAUDI-1099

   std::stol is more aggressive than ::strtol when given bad input. This results
   in Boole failing in the LHCb nightly builds. See GAUDI-1099.

   See merge request !31


! 2015-09-25 - commit 35dd00c

 - Merge branch 'dev-smartif-use' into 'master'

   Provide (and use) C++11 smart pointer 'look and feel' for SmartIF

   The aim of this branch is to confine, for everything that inherits from
   IInterface, the calls to addRef(), release() and queryInterface() to the
   SmartIF implementation. Exceptions are a few places where interfaces
   (currently) return bare pointers (instead of SmartIF...) and where one thus
   has to addRef() explicitly to avoid returning a dangling pointer. This can be
   avoided by changing the relevant interface to return a SmartIF instead of a
   bare pointer.

   In addition, make SmartIF 'look and feel' like a smart pointer.

   - use explict bool conversion instead of .isValid()
   - add SmartIF::as<IFace>(), to return a SmartIF<IFace> to an alternate
      interface -- which (together with move) encourages the use of auto
   - add ISvcLocator::as<IFace>(), to return a SmartIF<IFace> to the current
   ISvcLocator.
   - add ServiceManager::service<IFace>() which return SmartIF<IFace> which
   encourages
      the use of auto

   And add a few other C++11 modernizations (eg. prefer STL over raw loop)

   Fixes GAUDI-1094

      from GaudiKernel.Configurable import ConfigurableGeneric as RFileCnv

! 2005-08-15 - Hubert Degaudenzi
 - patch #506. Creating H2D and H3D histograms (function
   createPersistent) was creating wrong values for weights in some
   cases. This patch removes all the implementation code and calls the
   Aida Root histogram converter (from pi) instead (Stephan Roiser).
	Remarks:

   This includes:

   - the modified histogram converter classes H1DCnv, H2DCnv, H3DCnv,
     each responsible now for conversion of the corresponding fixed and
     variable bin size histograms (classes H1DVarCnv, H2DVarCnv,
     H3DVarCnv removed)
 - Added setting of statistics for 1D, 2D, 3D histograms being made persistent

   reading of 1D variable bin size histograms and 2D fixed bin size
   histograms possible
