Added and implemented file_id parameter to file tranfers.
file_id is a 32byte identifier that can be used by users to identify
file tranfers across core/client restarts in order to resume broken
file tranfers.

In avatar tranfers it corresponds to the hash of the avatar.

Added tox_file_get_file_id() function to api to obtain the file_id
of an ongoing file transfer.

If not set, core will generate a random one.
