EventInfo reading and conversion code moved from PileUpStream to
PileUpMergeSvc. Restored option to read old EventInfo in PileUpMergeSvc.
Setting SG pointer in const xAOD::EventInfo now possible.

Migrate from TAccept to AcceptData, for MT compatibility.

Migrate from TAccept to AcceptData, for MT compatibility.

Remove from D2PDSelectorBase references to IAthSelectorTool.
This interface uses TAccept but is implemented in master by only one tool,
AthTileTripReader.  Further, there seem to be no configurations which actually
configure D2PDSelectorBase to use AthTileTripReader.

Migrate from using TAccept to AcceptData.
Needed for MT compatibility.

In C++11, implicit declarations of copy and assignment are deprecated if the
class has a user defined destructor or copy or assignment.  gcc9 now warns
about this by default.
Adjust to avoid the warning.

TH1::GetRandom() and TH2::GetRandom2() are not MT-safe, since they're
non-const and also use gRandom.  These are used from
ParticleEnergyParametrization.  Rewrite so as to be const and to allow
passing in a random generator rather than having to use gRandom.
(We currently still pass in gRandom.  Changing that would change rng seeding,
so that will be fixed in a subsequent change.)

Run BS converter tests in both sequential and MT modes and ensure
that the results are identical.
