Replace IBM copyright headers with MIT copyright headers

The code still has internal IBM copyright headers. These need to be replaced with MIT copyright headers to match the actual license of the code. Especially phrases like this are incongruent with being "open source":

/* The Source code for this program is not published  or otherwise  */
/* divested of its trade secrets,  irrespective of what has been    */
/* deposited with the U.S. Copyright Office.                        */

I am assigning this to @ThePrez to make the decision that we can remove those.

I have updated the copyright headers and removed the sync version of the driver.
