I re-send this patch for review. I had to apply the patch to fix few random crashes on Windows using TURN

Hi,
regarding this old patch, there is still a problem.  The list  pending_permission contains all the pending TURN CreatePermission. When a new permission is stored in the list, a new timeout reminder is created and stored in the variable tick_source_create_permission overwriting the old value. 
I fixed this problem by creating just one timeout timer, the one that expires first. When that  timer expires, a new one is created with the next timeout value.

What do you think?

I send the patch for review. 

Regards,
Livio

Thanks for reviewing and fixing the patch. I had a look at the final result and I think it's OK.

Thanks,

I had a couple of issues with the patch, but I fixed them and committed, have a look at the final result :
http://cgit.collabora.com/git/libnice.git/commit/?id=d977c25410d89ab9028228c247b7751a965a0fb4

Changes :
- Removed trailing whitespaces and other small coding style inconsistencies
- Used the GList iterator in a deletion-safe way without using get_nth
- renamed variable to be less than 100 characters long :p
