scripts: Remove the old switch-timer-api script
This script has been useful for the timer API rewrite in 2013, but it is of no use anymore today. Let's remove it now. Message-Id: <20220124102001.35930-1-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

Translate each FILE to the new QEMU timer API. If no files

Options:

-q, --quiet Do not show warnings etc
