Did Harry really became unfrozen because DD died?

If the spells of a wizard stop working when they die (Harry 
unfreezing)... will the protection that DD casted on the Dursley's 
house for Harry still wok next summer?

What about other spells DD casted? Such as some protective spells over 
the castle? What about all the other protective spells.... Do they 
always have to be re-casted to keep the castle protected?

No. I do not believe that Harry became unfrozen because DD died. DD did 
not die..... and he lifted the spell on Harry to allow him to go after 
Snape/Malfoy and TRY to get them....
