Merge l1t-tsg-v6-cand and l1t-tsg-v7-cand into CMSSW

[mulhearn]

Now that the L1T integration branch has been rebased to CMSSW_8_0_7, we can prepare several PRs to update official CMSSW to l1t-tsg-v6-cand. Once l1t-tsg-v6 is declared (likely equal to l1t-tsg-v6-cand) we will make small incremental updates.

The relevant PRs for l1t-tsg-v6-cand are:

• external Updates to L1TCalorimeter data for l1t-tsg-v6 cms-data/L1Trigger-L1TCalorimeter#11 (merged)
• main pr 81x Update L1T to l1t-tsg-v6-cand (81x) cms-sw/cmssw#14364 (merged)
• ntuples 81x: Update L1T Ntuples for l1t-tsg-v6-cand  cms-sw/cmssw#14495 (merged)
• main pr 80x Update L1T to l1t-ts-v6-cand (80x) cms-sw/cmssw#14362 (merged)
• ntuples 80x: Update L1T Ntuples for l1t-tsg-v6-cand cms-sw/cmssw#14493 (merged)

The relevant PRs for l1t-tsg-v7-cand are:

• external Update data files for L1Trigger/L1TMuon. cms-sw/cmsdist#2302 (merged)
• main pr 81x: Update L1T to l1t-tsg-v7-cand performance (81x) cms-sw/cmssw#14535 (merged)
• Sven's TP update 80x: Correctly configure CSC trigger primitive emulator for Run2 (80X) cms-sw/cmssw#14419 (merged)

The PR for cleaning up unpacker error messages is here:

• 81x Clean-up L1T unpacker warnings cms-sw/cmssw#14591 (merged)
• 80x Clean-up L1T unpacker warnings cms-sw/cmssw#14617 (merged)

An additional PR for updates to handle OMTF muons at edge of OMTF acceptance is here:

• 81x Update OMTF treatment of Muon at edge of OMTF acceptance cms-sw/cmssw#14604 (merged)
• 80x Update OMTF treatment of Muons at edge of OMTF acceptance cms-sw/cmssw#14613 (merged)

PRs for 80x and 81x are ready. 80x will likely need a simple rebase when underlying PRs are merged.

Both PRs pass Jenkin's tests, but I'll run the problematic IB RelVals locally as well.

Looks like IB with l1t-tsg-v7-cand PR went well for us. No problems from us as far as I can tell:

The 80x PRs that bring us up to date with l1t-tsg-v7-cand are now in 80x too. We'll see how tonights IB goes. Last thing is to prepare the 80x version of the small incremental fixes for unpacker error quieting and the OMTF fix for muons at edge OMTF acceptance (already merged in 81x).
