Faster file transfers (up to 160ms/s)

Browse Source 
By reducing the maximum interval between two tox_iterate calls during file transfers to 10ms. This results in reasonnable amounts of extra CPU% used. If the only file transfers are avatars, CoreFile allows sleeping for up to 50ms. If there are currently no FT, up to 1000ms.

We now take the minimum sleeping interval asked by toxcore, toxav, and CoreFile
