    ! 2017-02-08 - Charles Leggett (commit 09859bd)

     - add sysExecute(EventContext) and extract errorCount from Algorithm base class

       We need to extract the `m_errorCount` variable from the Algorithm base class,
        as it's not important on a per-instance basis, but rather on a job level.
       This is moved to the AlgExecStateSvc.
        This merge request also adds an explicit `IAlgorithm::sysExecute(const
       EventContext&)`, which should become the standard entry point to
       `Algorithm::execute`. This sets the local m_event_context variable, so
       derived classes can get quick access to the current context instead of going
       through the slower thead local `Gaudi::Hive::currentContext()`.
        Note that `IAlgorithm::sysExecute()` has been removed, to avoid "overloaded
       virtual" compiler errors, and should be replaced in all clients with
       `IAlgorithm::sysExecute(EventContext)`, or if the context is not immediately
       available, with `IAlgorithm::sysExecute(Gaudi::Hive::currentContext())`.
        All this is being done in preparation to re-introduce the ReEntrantAlgorithm
       class from merge !177 (see also !274)

     - 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.

    ! 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.

    ! 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

     - Task #47619: Defer calls to OutputStreams in GaudiMP
       Added a class to record which streams should be triggered and a class to
       use the recorded informations to trigger the OutputStream instances:
       RecordOutputStream and ReplayOutputStream.

       To use the delayed write, one need to translate options like:

           mySeq.members.append(OutputStream('MyStream'))

       with something like:

           mySeq.members.append(RecordOutputStream('RecordMyStream',
                                                   OutputStreamName='MyStream'))

     - Patch #5471: fixes to be able to run LHCb applications via GaudiParallel.
       - For Gauss:
         - GMPBase.py:
           - DoFirstEvent(): Call GetHistoNames instead of GetList (nearly the same
             except of the line "rootFID = node.address().par()")
           - GMPComponent.__init__(): Distinguish the applications
           - GetEventNumber(): In Gauss, EventNumber must be given by the Reader due
             to correctly set the random seeds
           - Initialize() of worker: Interface to EventCounter in order to modify
             the counters from outside
           - Engine() of worker: Set EventCounter which is given by the reader
       - General:
         - GMPBase.py:
           - Go(): SUCCESS/FAILURE is not a bool --> if-statement did not work
           - Terminate(): Termination won't work when one of the processes already
             died. Check existing processes
           - Engine() of writer: runTime of writer was not correct as it was
             overwritten every time
           - DoFirstEvent(): Register links in TransientEventStore (DAQ/RawEvent)
           - WAIT_SINGLE_EVENT = 60*6: In certain situations it happened that the
             waiting time for the finalization was too short
           - Engine() of worker: ItemList and optItemList have been modified. Double
             entries caused a memory leak
         - TESSerializer.cpp:
           - loadBuffer(): Find objects, which are not equal to /Event in TES, and
             read out the buffers
         - pTools.py:
           - ProcessTimeSpanFSR(): Time Span in FileRecords are not generated
             correctly (no merging). Instead of writing n times TimeSpanFSR, only
             the minimum and maximum is written
           - syncAllRolling(): In Gauss it happened often that the Reader is too
             fast and could not synchronize with the workers in the end. As the
             synchronization object is not reset the Reader waits for a long time
             until it calls processHang() and kills every process. Modifying the
             if-statement allows to reset the waiting time of the Reader
         - compareOutputFiles.py:
           - Sets-module is deprecated
           - Added functions for the comparison of FileRecords (CompareFSR(),
             GetFSRdict(), CheckFileRecords())
