added a script to regenerate certificates easily in the future (2035!)
restored server8k-key.pem to actually be 8K key, as it was supposed to

Backport from mysql 5.7. The patch reviewed, test added.

DB-802 make.mysql.bash should extract and use the tokudb version as the git tag.  there was a broken RE

MDEV-6220 mysqldump will not backup database with --flush-logs parameter and log_error my.cnf parameter defined

some checks were "if [ -n "$err_log" ]", others were "if [ $want_syslog -eq 0 ]",

correct the check for PLUGIN_VAR_STR

mtr internally does the following:
1. $default_vardir=....
2. $opt_vardir=$default_vardir unless $opt_vardir;
3. $opt_vardir=realpath $opt_vardir unless IS_WINDOWS
4. if ($opt_vardir eq $default_vardir) { .... use /dev/shm ... }

thus we have to realpath $default_datadir too, otherwise
the comparison logic might be broken

add "mysql-compat-server" alias to MariaDB-server package

it's in the dead code (ifdef-ed out) so it doesn't matter what it is.
