Simplify scripts

[minad]

• remove updatemakes
• start to remove dep.pl (should be part of helper.pl)
• dep.pl is now part of helper.pl

@sjaeckel I hope we can avoid adding new scripts and put all the generation tasks inside helper.pl. dep.pl is a legacy script which is now also part of helper.pl. I transformed everything carefully in a few steps, so there should be no breakage.

there's one thing that breaks... no ./updatemakes.sh -c anymore ;)

Yes, that's intentional. I think it is better if the scripts don't mess with git and I never used this. Agree?

Haha, the git log agrees with me.

$ git log --oneline | grep 'Update makefiles$' | wc
