MDEV-28758: Mariabackup copies binary logs to backup directory

This commit restores defaults and functionality regarding binlogs
to the way it was prior to MDEV-27524. The mariabackup utility no
longer saves binlogs files as part of a backup without the --galera-info
option. However, since we use --galera-info during SST, the behavior
of mariabackup changes and, in combination with GTIDs support enabled,
mariabackup transfers one (most recent) binlog file obtained after
FLUSH BINARY LOGS. In other cases, binlogs are not transferred during
SST in mariabackup mode. As for SST in the rsync mode, as it was
before MDEV-27524 - it transfers one last binlog file by default.

The --sst-max-binlogs option for mariabackup and the sst_max_binlogs
parameter in the [sst] / server sections are no longer supported for
SST via mariabackup.

MDEV-26562: galera-sst-mariabackup is failing due to missing xtrabackup_checkpoints

This commit contains workaround for a bug known as 'Red Hat issue 1870279'
(connection reset by peer issue in socat versions 1.7.3.3 to 1.7.4.0) which
further causes crashes during SST using mariabackup (when openssl is used).

Also fixed broken logic of automatic generation of the Diffie-Hellman parameters
for socat version less than 1.7.3 (which defaults to 512-bit values instead of
2048-bit ones).

MDEV-28583: Galera: binlogs disappear after rsync IST

This commit sends a flag indicating the presence of the "--bypass"
option from the donor node to the joiner nodes during rsync IST,
because without such a flag it is impossible to distinguish IST
from the SST on the joiner nodes (in IST/SST scripts, because the
"--bypass" option is still not passed to scripts from server code).
Specifically, this fixes an issue with binary logs disappearing
after IST (via rsync). There are also changes to diagnostic messages
here that will make it easier to diagnose script-related problems
in the future when debugging and when checking the logs. This commit
also adds more robust signal handlers - to handle exceptions during
script execution. These handlers won't mask some crashes and it
also unifies exit codes between different scripts. These changes
have already been helpful to debugging "bypass" flag handling.

MDEV-28423: Galera IST is failing on Joiner node

This commit fixes an issue with IST handling in
version 10.9 which is a regression after MDEV-26971
and related to trying to get a non-existent "total"
tag on the IST branch (this tag is only defined in
SST mode).

MDEV-28552 Assertion `inited==RND' failed in handler::ha_rnd_end

We cannot permanently change bits in read_partitions in the middle of
processing because ha_rnd_init()/ha_rnd_end() depends on that.
