[Development] ChangeLog script will need adaptation to cherry-pick model

[Thiago Macieira]

I've just noticed this and it'll be relevant for the 6.0 release: the 
ChangeLog script currently excludes the previous releases' commits simply 
because they aren't produced in the git log / rev-list output. Because we 
switched to cherry-pick model, the commits are now different and will not be 
excluded by Git itself.

Someone has to adapt this script to go over the list of commits in the 
previous releases and see if the same commit message or same Change-Id is 
present. Instead of a DAG operation in the commit history, this is a text 
search.

If I were to implement this, I'd create a QSet-equivalent of all Change-Ids 
that apply to the previous branch series that were cherry-picked since the 
branch point.
