executor: Protect the coverage buffer
Add functions to protect and unprotect the coverage buffer. The buffer is
protected from being written to while tracing. When the trace data is
sorted we need to make it read/write, but can return it to read only after
this has completed.
Leave the first page as read/write as we need to clear the length field.
