  in this version. Sure enough, it never caused any improvement in
  the execution speed and rather caused a small increase of execution
  time. This is probably because values are sorted by rowid in each
  range of CONNECT indexes. This could be reconsidered if a customer
  have a need for processing very big files.

it didn't help, instead it only broke upgrades even more

Unlike MyISAM, InnoDB does not support boolean full-text searches on 
nonindexed columns, but this restriction was not enforced, resulting 
in queries that returned incorrect results. (Bug #16434374)

appears to be unset, or when it contains 'root' even though the user
does not have real root permissions

Turned off Performance Schema for Spider test suite

Rules performed unnecessary copying which made tests run with wrong
global testdir

Port to mariadb-1.0 the following fix from mysql-5.6:

  Revision ID: jorgen.loland@oracle.com-20120314131055-ml54x9deueqfsff4
  BUG#13701206: WHERE A>=B DOES NOT GIVE SAME EXECUTION PLAN
                AS WHERE B<=A (RANGE OPTIMIZER)
 
that fix didn't have a public testcase, so I created one.

which has been removed earlier, but somehow got into the sources again.

This file is not really needed, and it prints warnings
"sys/timeb.h is deprecated" for every file when compiling on FreeBSD.
