Marko Mäkelä b249a059da MDEV-34850: Busy work while parsing FILE_ records
In mariadb-backup --backup, we only have to invoke the undo_space_trunc
and log_file_op callbacks as well as validate the mini-transaction
checksums. There is absolutely no need to access recv_sys.pages or
recv_spaces, or to allocate a decrypt_buf in case of innodb_encrypt_log=ON.
This is what the new mode recv_sys_t::store::BACKUP will do.

In the skip_the_rest: loop, the main thing is to process all FILE_ records
until the end of the log is reached.  Additionally, we must process
INIT_PAGE and FREE_PAGE records in the same way as they would be
during storing == YES.

This was measured to reduce the CPU time between the messages
"InnoDB: Multi-batch recovery needed at LSN" and
"InnoDB: End of log at LSN"
by some 20%.

recv_sys_t::store: A ternary enumeration that specifies how records
should be stored: NO, BACKUP, or YES.

recv_sys_t::parse(), recv_sys_t::parse_mtr(), recv_sys_t::parse_pmem():
Replace template<bool store> with template<store storing>.

store_freed_or_init_rec(): Simplify some logic. We can look up also
the system tablespace.

MariaDB: The innovative open source database

MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.

A description of the MariaDB project and a manual can be found at:
