SampleSecondaries(); avoid crash when the loop of SampleSecondaries()
is inkoved in a unit test.

+ Standard:
o Bug fix in G4UrbanMscModel; 1st normal step in StepLimitType 2 mode
was not randomized.
Move methods ComputeTheta0,SimpleScattering(), SampleDisplacement(),
LatCorrelation() to be inlined for small CPU speedup.

Reduced number of divisions by addition of extra class members.
o G4NuclearStopping: fix to avoid changing ion charge.
o G4ionIonisation: do not instantiate extra model at high enegry if

o G4SauterGavrilaAngularDistribution: use Penelope 2008 sampling
algorithm, as it is more effective; distribution itself is unchanged.
o G4GoudsmitSaundersonMscModel, G4GoudsmitSaundersonTable: use G4Log(),
and G4Exp().
o G4eCoulombScatteringModel, G4eSingleCoulombScatteringModel: get pointer
to the vector of cuts from parameters of Initialise(..) method and not
from G4ProductionCutsTable; more convenient for unit tests.
o Fixed Coverity defects.
+ Utils:
o G4VEnergyLossProcess: fixed division by zero for the case of an ion
with charge zero.
o G4EmCalculator: in FindCouple() method, implemented loop over all
regions if argument pointer to region of the method is null.
Added G4Exception if G4MaterialCutsCouple is not found out and
also inside GetCSDARange() when CSDA table is not initialized.
o G4LossTableMananger: fixed bug for initialisation of several runs
in one job (affecting muons and e- and providing non-reproducibility)
o G4LossTableMananger, G4EmProcessOptions: define default verbosity=0
for worker thread, so summary on EM processes is not duplicated.
o G4VEnergyLossProcess, G4VEmProcess: define fixed precison=6 for
initialisation printout.
+ xrays:
o Make some class members and methods static in G4Cerenkov and
G4Scintillation.
o Generic Processes:
-----------------
+ Cuts:

G4BGGNucleonInelasticXS.
+ management:
o Added printout of energy momentum check in G4HadronicProcess.
+ models/binary_cascade:
o G4BinaryLightIoncascade::FuseNucleiAndPrompound(): added protection at
low energy: available energy is not sufficient to create a fragment.
o G4BinaryLightIonReaction: fix for Coverity report on small leak.
o Added printout of particle name in check for valid type of projectile
in G4BinaryCasacde::ApplyYourself().
+ models/de_excitation:
o G4ExcitationHandler: fixed minor memory leak in the case when
FermiBreakUp has no final states available; reported in item
#1371 in hypernews Hadronic forum.
o G4NuclearLevelManager: trivial fix for defect reported by Coverity.

Should help reducing memory churn and improve CPU performance.
Removed counter of warnings; added exception warning in verbose mode.
+ stopping:
