MDEV-5363: Make parallel replication waits killable

Browse Source 
Add another test case. This one for killing a worker while its transaction is
waiting to start until the previous transaction has committed.

Fix setting reading_or_writing to 0 in worker threads so SHOW SLAVE STATUS can
show something more useful than "Reading from net".
