b96697d286 MDEV-6648: InnoDB: Add support for 4K sector size if supported 
New generation hard drives, SSDs and NVM devices support 4K
sector size. Supported sector size can be found using fstatvfs()
or GetDiskFreeSpace() functions.

56c4b016ad Fiix random test failures on fil_decompress_page_2 function. 
Analysis: InnoDB writes also files that do not contain FIL-header.
This could lead incorrect analysis on os_fil_read_func function
when it tries to see is page page compressed based on FIL_PAGE_TYPE
field on FIL-header. With bad luck uncompressed page that does
not contain FIL-headed, the byte on FIL_PAGE_TYPE position could
indicate that page is page comrpessed.

Fix: Upper layer must indicate is file space page compressed
or not. If this is not yet known, we need to read the FIL-header
and find it out. Files that we know that are not page compressed
we can always just provide FALSE.

13c73c31c3 Added support for LZO compression method. 
Removed: innodb_use_lz4 configuration parameter

Added: innodb_compression_algorithm configuration parameter
0 = no compression, 1 = ZLIB, 2 = LZ4, 3 = LZO

Fixed issue with incorrect trim calculations

7322270a05 Set actual compressed page size also on read code path to buffer pool so 
that we can later use it to avoid unnecessary trim operations.

8c5d5bc5de Fixed merge error on InnoDB page compression level handling. 
Merged page compression feature to XtraDB storage engine.

Added feature where page compression can use lz4 compression
method (innodb_use_lz4, default OFF).
