MDEV-7888, MDEV-7929: Parallel replication hangs sometimes on ANALYZE TABLE or DDL

Browse Source 
Follow-up patch with 10.1-specific changes.

Add test cases that more closely resembles the original bug report (which uses
the 10.1-specific --slave-parallel-mode=optimistic).

Also fix the code so that ANALYZE statements are now marked as DDL, and will
not be attempted to speculatively run in parallel with other transactions.
