remove a couple of old unused #defines
Increased the version number
MDEV-6354: Implement a way to read MySQL 5.7.4-labs-tplc page
compression format (Fusion-IO).

Addeed LZMA and BZIP2 compression methods.
MDEV-6456: Add progress indication for "Reading tablespace information from the .ibd files"

# of processed files is printed every 15 sec.
Fix default value for innodb_compression_algorithm to 0 (uncompressed)
to avoid test failures.
Merge branch '10.1' of github.com:MariaDB/server into 10.1
Added default_role column to mysql_system_tables
Added extra error messages for default role.

Also fixed wording on one message.
Added default role implementation
Fixed comment.
Extended create_and_drop_role_invalid_user_table

Added extra check for default_role column.
Changed set_default_role_for test to clean up correctly
cleanup and updated test results
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.
Fix compiler error on Windows.
Fix compiler error on Windows.
MDEV-6512: InnoDB: Assertion failure in thread 4537024512 in file
buf0buf.cc line 2642.

Analysis: innodb_compression_algorithm is a global variable and
can change while we are building page compressed page. This could
lead page corruption.

Fix: Cache innodb_compression_algorithm on local variable before
doing any compression or page formating to avoid concurrent
change. Improved page verification on debug builds.
MDEV-5834: Merge Kakao Defragmentation implementation to MariaDB 10.1

    Merge https://github.com/kakao/mariadb-10.0 that contains Facebook's
    implementation for defragmentation

    facebook/mysql-5.6@a2d3a74
    facebook/mysql-5.6@def96c8
    facebook/mysql-5.6@9c67c5d
    facebook/mysql-5.6@921a81b
    facebook/mysql-5.6@aa519bd
    facebook/mysql-5.6@fea7d13
    facebook/mysql-5.6@09b29d3
    facebook/mysql-5.6@9284abb
    facebook/mysql-5.6@dbd623d
    facebook/mysql-5.6@aed55dc
    facebook/mysql-5.6@aad5c82

    This version does not add new SQL-syntax and new handler API function.
    Instead optimize table is mapped to defragment table if
    innodb_defragment=ON, by default the feature is off.

    Contains changes authored by Sunguck Lee (Kakao).
MDEV-6247: Merge 10.0-galera to 10.1.

Merged lp:maria/maria-10.0-galera up to revision 3867.
Fix Windows compiler error by disabling for now the nullptr class
implementation.
