fix last commit - I missed that the parameter I was changing was already there
Fixes needed after RelVal input removal at CERN.
Updated ProcInfoFetcher to match linux 2.6 interface

The code was using an old format of the proc info system. This caused a parsing problem which caused the program to write lots of warnings. This should bring our code up to the linux 2.6 standard.
Fixed bug that cause Service exceptions to cause aborts

If a Service threw an exception during the ending of a processing transition (e.g. end of Event), the exception would cause an abort rather than being propagated as expected.
The problem was the Service signal was generated during the destructor of a 'guard' class instance. In C++11 those destructors are now implicitly noexcept(true) which caused the abort.
The destructor were changed to noexcept(false) and a new method 'allowThrow()' was added which is used to avoid throwing an exception while an exception is being propagated out
of the function which uses the guard.

This fix was already introduced to CMSSW_7_0_X but given the large changes between the two releases this had to be reimplemented by hand.
cmsRun returns non-zero if caught unix signal

If any of the signals cmsRun catches (SIGINT and SIGUSR2) are caught, cmsRun now returns a non zero value. This was requested by data ops.
Backported from CMSSW_7_0_X.
