Bug#37716.

Browse Source 
1. Test case was rewritten completely.
2. Test covers 3 cases:
 a) do deadlock on slave, wait retries of transaction, unlock slave before lock
timeout;
 b) do deadlock on slave and wait error 'lock timeout exceed' on slave;
 c) same as b) but if of max relay log size = 0;
3. Added comments inline.
4. Updated result file.
