6b671aeee3 MDEV-29710: Disable some more tests on Valgrind
A number of tests often trip warnings on Valgrind, because Valgrind
runs all threads in a single thread and may cause starvation:
InnoDB: A long wait (... seconds) was observed for dict_sys.latch

Let us disable those tests on Valgrind in order to avoid bogus failures.

beec9c0e19 MDEV-21255: Deadlock of parallel slave and mariabackup (with failed log
copy thread)

mariabackup hangs waiting until innodb redo log thread read log till certain
LSN, and it waits under FTWRL. If there is redo log read error in the thread,
it is finished, and main thread knows nothing about it, what leads to hanging.
As it hangs under FTWRL, slave threads on server side can be blocked due
to MDL lock conflict.

The fix is to finish mariabackup with error message on innodb redo log read
failure.
