MDEV-33361 Excessive delays in SET GLOBAL innodb_log_file_size
innodb_log_file_size_update(): Wait for buf_pool.done_flush_list
(that a flush batch has completed), not buf_pool.do_flush_list
(that the buf_flush_page_cleaner was woken up).
The condition variable buf_pool.done_flush_list is broadcast by the
buf_flush_page_cleaner() at the end of each batch, which is when the
log checkpoint can advance and where any log resizing may be completed.
The purpose of the condition variable buf_pool.do_flush_list is to
wake up the buf_flush_page_cleaner() thread because there is work to do.
If no thread is signaling that condition variable, this loop could
unnecessarily wait for up to 5 seconds too long for the log resizing
to be completed. By consuming signals it could also prevent the
buf_flush_page_cleaner() thread from waking up.
MDEV-33095 MariaDB-backup - no OS_DATA_FILE_NO_O_DIRECT on some platforms
Postfix for a6290a5bc5f3cba096854595c354d19d9267743d, in 10.11
where OS_DATA_FILE_NO_O_DIRECT gets used. Same #ifdef conditions
as other uses of OS_DATA_FILE_NO_O_DIRECT.
Noticed on aarch64-macos builder.

MDEV-30839: Add new options to mini-benchmark and fixes
Add new options to mini-benchmark.sh so it is more useful, such as
`--log` to avoid output from `lscpu` and other commands being lost.
Also fix following errors:
- Fix if condition for the cycle count regression verdict. The condition
checked if the cycle count was greater than 850 billion, but `$RESULT`
is only 3 digits and represents the number of cycles in billions.
- Fix flamegraph width. The original width caused the flamegraph to be
cut-off on most screen sizes in the browser.
- Fix ShellCheck warnings and suggestions.
- Fix condition to check if perf has permission to run on the system.

Still not ready to support mariadb-plugin-rocks by distro.
pmem (despite its EOL on Intel) and liburing are available on Noble
(24.04). Its unclear why they where disabled in lunar/jammy. Too
unstable to change now so introduce to 24.04 and see how it goes
during testing.
Some old versions of "patch" (such as patch 2.5.9 on Microsoft Windows)
require that a file name header be present.
To ensure that the diff will be applied, let us add the header.
MDEV-32242 fixup: innodb.doublewrite test may be skipped again
It is not sufficient to sleep for only 1 second to
ensure that the page cleaner has gone idle.
The timings could have been changed compared to earlier releases
by commit a635c40648519fd6c3729c9657872a16a0a20821 (MDEV-27774).
Let us allow the non-debug test innodb.doublewrite to be skipped,
and remove the insufficient 1-second sleep.
