Also, apply the MDEV-17957 changes to encrypted page checksums,
and remove error message output from the checksum function,
because these messages would be useless noise when mariabackup
is retrying reads of corrupted-looking pages, and not that
useful during normal server operation either.
The error messages in fil_space_verify_crypt_checksum()
should be refactored separately.
Rewrite the test encryption.innodb-checksum-algorithm not to
require any restarts or re-bootstrapping, and to cover all
innodb_page_size combinations.
Test innodb.101_compatibility with all innodb_page_size combinations.
Problem was that checksum check resulted false positives that page is
both not encrypted and encryted when checksum_algorithm was
strict_none.
Encrypton checksum will use only crc32 regardless of setting.
buf_zip_decompress: If compression fails report a error message
containing the space name if available (not available during import).
And note if space could be encrypted.
buf_page_get_gen: Do not assert if decompression fails,
instead unfix the page and return NULL to upper layer.
fil_crypt_calculate_checksum: Use only crc32 method.
fil_space_verify_crypt_checksum: Here we need to check
crc32, innodb and none method for old datafiles.
fil_space_release_for_io: Allow null space.
encryption.innodb-compressed-blob is now run with crc32 and none
combinations.
Note that with none and strict_none method there is not really
a way to detect page corruptions and page corruptions after
decrypting the page with incorrect key.
New test innodb-checksum-algorithm to test different checksum
algorithms with encrypted, row compressed and page compressed
tables.
