     - added ConcurrencyFlags class

       The static ConcurrencyFlags allows easy access to information about the
       number of threads, concurrent events, and processes.
        For running in serial, numThreads == 0, numConcEvents == 0, numProcs == 0,
       useful to distinguish between running serial, and running MT with 1 thread,
       or MP with 1 process.

     - 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)

     - Change of terminology within the graph-based scheduler

       This is a minor MR that introduces more accurate terminology within the
       graph-based scheduler. In particular, the `ExecutionFlowGraph` is renamed to
       `PrecedenceRulesGraph`.

     - 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.

     - 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.

     - Algorithm Execution State Service

       Introduction of AlgExecStateSvc
        All event state information removed from Algorithm base class
       (m_filterPassed, m_isExecuted) as it will cause difficulties with re-entrant
       Algorithms.
        event success/fail flag removed from EventContext
        These flags are moved to be under control of a new service, the
       AlgExecStateSvc, which keeps track of the execution state of all Algorithms,
       and the Event as a whole.
        Algorithm status kept in a new class ```AlgExecState``` which has
       ```
           bool m_filterPassed  {true};
           bool m_isExecuted    {false};
           StatusCode m_execStatus  {StatusCode::FAILURE};
       ```
        AlgExecStateSvc holds an AlgExecState for each Algorithm in each Event
       Slot, as well as an overall ```EventStatus``` for each EventSlot, which can
       be one of

       ```
         Invalid = 0,
         Success = 1,
         AlgFail = 2,
         AlgStall = 3,
         Other = 4
       ```
        Algorithms add themselves to the AlgExecStateSvc upon initialization, but
       the Service's initialization of  the data structures is deferred until the
       first time ```AlgExecStateSvc::reset()``` is called, at which point it's
       probably safe to figure out if there's a WhiteBoard, and the number of slots
       to allocate.
        The EventLoopMgr should call ```AlgExecStateSvc::reset()``` at the start of
       each event. If it's a concurrent EventLoopMgr, it should be
       ```AlgExecStateSvc::reset(EventContext)```, after the EventContext object
       has been updated to reflect the new event.
        Also added an EventContext object to the MinimalEventLoopMgr, so that
       serial/concurrent behaviour is similar.
        Concurrent queries to the AlgExecStateSvc must contain the EventContext, so
       the correct EventSlot can be determined. Serial access is via methods that
       don't have the EventContext as a parameter. For access from Algorithm base
       class (eg from setFilterPassed, isExecuted, etc), if the EventContext ptr
       (m_event_context) in the Algorithm is null, we assume we're running
       serially.

     - ThreadPoolSvc: Bugfix/barrier fix

       (from Steve Farrell) see https://gitlab.cern.ch/atlas/Gaudi/merge_requests/17

        This merge fixes a serious undefined behavior condition in ThreadPoolSvc
       introduced in the thread-tool-terminate merge. The boost::barrier was moved
       to a function local which could drop out of scope before workers returned
       from waiting. Now, the barrier is again a class member of the ThreadPoolSvc.
       Tests are successful. Additionally, I added a safety check in
       ThreadPoolSvc::terminateTool that returns FAILURE if the pool wasn't actually
       initialized.
        Finally, I put the ThreadPoolSvc's raw pointer class members into
       unique_ptrs for automatic deletion.

     - Thread tool termination

       This set of changes completes the work started by @leggett in
       a875c69e3ac6b1d1253e4086daea076860a95e52 on thread initialization tools. Such
       tools are invoked by the ThreadPoolSvc on each worker thread when the pool is
       initialized and can be used to setup thread-local workspaces in cases where
       necessary (e.g. for running multi-threaded Geant4).
        These commits enable the thread-termination part of those tools for
       corresponding cleanup/finalization of thread-local memory. This is done
       primarily by adding a terminatePool method to IThreadPoolSvc which is called
       at the end of ForwardSchedulerSvc::activate. The ThreadPoolSvc underwent some
       slight refactoring to support the thread-termination tasks.
        Also included in this merge request are a number of whitespace and
       indentation fixes, as well as some added class documentation in the affected
       classes.

     - Isolate EventContext from Algorithm

       in order to not have re-entrant Algorithms stomp on each others'
       EventContexts, we need to isolate the EventContext from the Algorithm, and
       move it to the AlgoExecutionTask. We can then pass the EventContext
       explicitly to the tbb::task, instead of carrying it via the Algorithm, which
       would fail for re-entrant Algs. This also requires a change to the signature
       of ForwardSchedulerSvc::promoteToExecuted.
        We should also make the EventContext* of the Algorithm const, to prevent any
       modification from inside the Alg.

     - use StringKey for Alg name, add IAlgorithm::setIndex

       this patch does 3 things:

       - makes Algorithm::index() const (as it should have been), set the initial
       value to 0 instead of 123 (!)
       - adds a protected Algorithm::setIndex(unsigned int) method. this allows you
       to distinguish between clones. AlgResourcePool is the one who does the
       setting, and is declared as a friend to IAlgorithm
       - turns Algorithm::m_name into a StringKey (from a string), so we can hash on
       the name of Algorithms more easily (a useful ability when dealing with Alg
       clones, and trying to treat them all the same way)

     - better failure handling during initialization

       Several essential services that fail initialization during the

       the errors aren't propagated, and the job doesn't
     abort.
