Added the manually specified cmake variable named NoAcs.  Please note that this variable currently has no effect when building the CTA rpms

Created initial (incomplete) logging of timings for generic popping from container.

Adapted the in-RPM script generation.

The same variable is now used in all cases.

Added options, suppressions and re-implemented BackendVFS::AsyncLockfreeFetcher to try and make valgrind happy.

Replaced set_target_properties( .. .. INSTALL_RPATH ..) with set_property (TARGET .. APPEND PROPERTY INSTALL_RPATH ..)

Proceed all successful reports asynchronously and periodically check
and clear statuses if they have finished.
In the end of session do the check/flush for all reports in the
successful reports queue.

Switch from synchronous rados remove to async aio_remove in
case of zero size object in BackendRados::AsyncUpdater

Added many conditional printouts in unit tests. Those printouts are controlled by #defines in a central file.

Fixed calls to promise::get_future() after possible access form other thread. They are now guaranteed to happen before.
Added helgrind annotations for promise based synchronisation.
Added macros enabling helgrind annotations for shared_ptr.
Added suppression for shared_ptr used inside other standard lib object and not covered by the previous macros.
Added unit test for lower level .
Added suppressions for reported race conditions in Rados library.
Review heavily MemArchiveQueue and fixed missing commit in object store, leading to potentially orphaned objects.
Enabled formerly disabled test as it is now fast enough.

This is done by replacing unique_ptr/bare pointer with 2 shared_ptr.
Also added suppressions for helgrind complains about rados.

Added mechanism to make sure the ArchiveQueue lock is released only after all requests
have had their ownership updated.
