Update L1TNuples to l1t-tsg-v5, and address memory management problems.

[mulhearn]

This brings L1TNtuples up-to-date with l1t-tsg-v5. It adds additional updates for memory management as requested by David.

This supersedes #14028.

The same branch can now be used for both 80x and 81x PRs. Past experience has taught me that force pushing such a branch to the original PR 14028 will not work nicely as one would expect, and lots of people will get unnecessary e-mail. So just making a new 81x PR.

This passes our internal tests and does not change algorithm.

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar
