Introduce a new InnoDB redo log format for MariaDB 10.3.1
The redo log format will be changed by MDEV-12288, and it could
be changed further during MariaDB 10.3 development. We will
allow startup from a clean redo log from any earlier InnoDB
version (up to MySQL 5.7 or MariaDB 10.3), but we will refuse
to do crash recovery from older-format redo logs.
recv_log_format_0_recover(): Remove a reference to MySQL documentation,
which may be misleading when it comes to MariaDB.
recv_log_recover_10_2(): Check if a MariaDB 10.2.2/MySQL 5.7.9
redo log is clean.
recv_find_max_checkpoint(): Invoke recv_log_recover_10_2() if the
redo log is in the MariaDB 10.2.2 or MySQL 5.7.9 format.
