Add a friend to the friend list and send a friend request.
A friend request message must be at least 1 byte long and at most TOX_MAX_FRIEND_REQUEST_LENGTH.
Friend numbers are unique identifiers used in all functions that operate on friends. Once added, a friend number
is stable for the lifetime of the Tox object. After saving the state and reloading it, the friend numbers may
not be the same as before. Deleting a friend creates a gap in the friend number set, which is filled by the next
adding of a friend. Any pattern in friend numbers should not be relied on.
If more than INT32_MAX friends are added, this function causes undefined behaviour.

Add a friend without sending a friend request.
This function is used to add a friend in response to a friend request. If the client receives a friend request,
it can be reasonably sure that the other client added this client as a friend, eliminating the need for a friend
request.
This function is also useful in a situation where both instances are controlled by the same entity, so that this
entity can perform the mutual friend adding. In this case, there is no need for a friend request, either.
