Replace verbatim license text with a `SPDX-License-Identifier` The comment header mis-attributes this license to be "X11", but the license text does not include the last line "Except as contained in this notice, the name of the X Consortium shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software without prior written authorization from the X Consortium.". Therefore, this license is actually equivalent to the SPDX "MIT" license (confirmed by text diffing).
