The main changes in this version are following.
- The standalone compilation with Vertical Partitioning storage engine is now available.

- Vertical Partitioning can be used for multi-step partitioning.
  Example:
    create table a(a int primary key)engine=myisam;
    create table b(a int primary key)engine=vp comment 'tnl "a"';
    create table c(a int primary key)engine=vp comment 'tnl "b"';

- Add table parameter "bgs_mode", "bgi_mode" and "bgu_mode".
- Add server parameter "vp_bgs_mode", "vp_bgi_mode" and "vp_bgu_mode".
  Parallel search and update from Vertical Partitioning to Spider are now available by using this parameters.
