Macros need to compile in ROOT6 (ALCA) (7_4_X)

[wmtan]

In ROOT6 macros are processed by cling, rather than CINT. Over 500 CMSSW macros do not compile in ROOT6. Since that is too many macros to be fixed centrally, it was decided by David Lange to centrally fix only those 45 macros with compilation errors that have been modified since the switch over to git, since those are the ones most likely to be used. Only four of these 45 macros are in the ALCA L2 category. This pull request fixes them.

It appears that these changes are OK for ROOT5, but I can't be 100% sure.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @ktf, @smuzaffar
