Commit timestamp abbreviations

I noticed this when looking at the allocated shared memory structures in
head:
shared memory alignment 64-byte of CommitTs Ctl:  0shared memory alignment 64-byte of CommitTs shared:  0

I thought we got rid of the idea that 'Ts' means timestamp.  Was this
part forgotten?

Do you have a specific reference?  That's not the concern I remember,
and I sure don't want to re-read that whole thread again.

I remember the issue of using _ts and 'ts' inconsistently, and I thought
we were going to spell out timestamp in more places, but maybe I am
remembering incorrectly.

The change was from committs to commit_ts + CommitTs depending on place.
