The following options will be removed:
innodb_file_format
innodb_file_format_check
innodb_file_format_max
innodb_large_prefix
They have been deprecated in MySQL 5.7.7 (and MariaDB 10.2.2) in WL#7703.
The file_format column in two INFORMATION_SCHEMA tables will be removed:
innodb_sys_tablespaces
innodb_sys_tables
Code to update the file format tag at the end of page 0:5
(TRX_SYS_PAGE in the InnoDB system tablespace) will be removed.
When initializing a new database, the bytes will remain 0.
All references to the Barracuda file format will be removed.
Some references to the Antelope file format (meaning
ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT) will remain.
This basically ports WL#7704 from MySQL 8.0.0 to MariaDB 10.3.1:

lz4.cmake: Check if shared or static lz4 library has LZ4_compress_default
function and if it has define HAVE_LZ4_COMPRESS_DEFAULT.
fil_compress_page: If HAVE_LZ4_COMPRESS_DEFAULT is defined use
LZ4_compress_default function for compression if not use
LZ4_compress_limitedOutput function.
Introduced a innodb-page-compression.inc file for page compression
tests that will also search .ibd file to verify that pages
are compressed (i.e. used search string is not found). Modified
page compression tests to use this file.
Note that snappy method is not included because of MDEV-12615
InnoDB page compression method snappy mostly does not compress pages
that will be fixed on different commit.
Change default to zlib, this has effect only if user has
explicitly requested page compression and then user
naturally expects that pages are really compressed
if they can be compressed.
