Check the killed state of a connection
@details
In MySQL support for the KILL statement is cooperative. The KILL
statement only sets a "killed" flag. This function returns the value
of that flag. A thread should check it often, especially inside
time-consuming loops, and gracefully abort the operation if it is
non-zero.
@param thd user thread connection handle
@retval 0 the connection is active
@retval 1 the connection has been killed
