Better Windows support in the scripts directory
mysql_config.pl.in, mysql_install_db.pl.in:
New Perl version of Unix shell script, mainly for Windows
Many files in scripts directory:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
- Improve mysql_upgrade and add comments describing it's logic
- Don't look for mysql and mysqlcheck randomly, use dir where mysql_upgrade
was started from
- Don't look for mysql_fix_privilege_tables.sql randomly, compile
in the mysql_fix_privilege_tables.sql file and use that to upgrade
the system tables of MySQL
- Check for any unexpected error returned from runnning the mysql_fix_privilege_tables SQL
- Fix bug#26639, bug#24248 and bug#25405
