Draft: Fix #1: Disable note for simple-streams and gray-streams
Cmucl supports both simple-streams and Gray streams. Such support
requires changing the function signatures for at least listen and
clear-input.
Here is a list of tests affected by :assume-no-simple-streams:
clear-input.error.1clear-input.error.2file-length.error.4file-length.error.11file-length.error.12listen.error.1stream-element-type.5stream-element-type.6
For :assume-no-gray-streams:
file-length.error.4file-length.error.11file-length.error.12
