The tests have been changed such that the return value of
sftp_aio_begin_*() functions is expected to be a ssize_t
which indicates the number of bytes for which the function
sent a read/write request or error.
Tests for trying to read/write bytes more than the max limit
enforced by the API have also been added.
The negative tests for reading and writing have also been
seperated for the sake of clarity.
