clang required explicit default constructor call

Had to explicitly add universal initializer syntax to instantiation
of a temporary const object.
Moved functions from an unnamed namespace to avoid clang problems

clang complained that 'sign' was not being used because the templated
function which used it was not being instantiated in a given object
file. However, since declaring unnamed namespaces in a header is a
bad idea anyway, I moved one function to be a static member of the
template (since it was also templated on the same type) and put
'sign' into a unique namespace.
Fixed bug in BoostedJetMerger and made it a edm::stream::Producer

BoostedJetMerger had the wrong signature for beginJob and therefore
that function was never called (caught by clang). However, neither
beginJob nor endJob did anything so those methods were removed.
In addition, it was safe to change BoostedJetMerger to an
edm::stream::Producer and therefore become efficient when running
with multiple threads.
Protect Electron DQM code from missing MonitorElements

Added needed additional protection for case where a MonitorElement
is missing from the DQMStore.
This fixes a crash seen in the threaded IB RelVals.
