Review/all warning fixes

[QbProg]

This includes:

• Changes applyed to previous pull request by Denis
• "Interval" behavoir fix (pourSGI)
• Some other warning fixes done yesterday, mainly uninitialized vars

I've reviewed again the changes, and there should not be evident problems nor breaking changes.
Someone can just double-check them?

My only concern is that there are 4 commits modifying IntCurve_IntConicConic_Tool.cxx, but

$ git diff master origin/review/all-warning-fixes -- src/IntCurve/IntCurve_IntConicConic_Tool.cxx

So it would be better to rewrite this branch again to avoid do/undo commits, but if you do not know how to do that, I won't oppose this merge, it is better to have this branch merged as soon as possible.

Sorry, that's my fault, the correction took 3 commits instead of 1 due
to stupid errors.

I imagine how to rewrite it (rebase -i I guess :), but will not have
the time to do this really soon.
So if someone else has the chance to do this in short time, we'll
wait, else for this time let's just merge the branch and look forward
for other
changes.

As I wrote in my previous comment, no problem for me, and when you have time, take a few minutes to learn to use git rebase -i, no doubt you will find this command incredibly awesome. But be warned that you may then want to rewrite everybody's branches to improve them, this is addictive ;-)
