Release/6.3.0

[fkonvick]

This is the (hopefully complete) collection of my changes to Gecode for 6.3.0. I did not create a separate branch for each change but hopefully the changes are simple enough to review.

Hi @fkonvick - thanks for this.

I tried building this PR, but got an error (on macos, arm processor)

I remember getting this error in the past but I am not sure what the fix was, sorry.

Thanks for trying. I think that this might be unrelated to my changes - could you successfully build the 6.3.0 release branch as is, without the PR applied?
I would think that parser.tab.hpp is a product of some Flex/Bison build steps, so perhaps your build configuration is missing these, or Perl.

[ozgurakgun]

I think you are right.

[fkonvick]

@zayenz Thanks. I got a notification saying "Gecode release/6.3.0" and I thought wow :) but then I realized it was just a merge. If there's anything I can do to help, please let me know!

[zayenz]

Yep, the branch name merged was a bit conspicuous.

Trying to get everything squared up now, and will check in on your build during next week.
