bzr push into mysql-5.1-telco-7.0 branch (ole.john.aske:4972 to 4973) Bug#14524939

[Ole John Aske]

 4973 Ole John Aske	2012-09-13
      Fix for bug#14524939 NDBMTD CRASH AT STARTUP IF CONFIGURED WITH MULTIPLE RECEIVER THREADS
            
      Fix ensures that idx[i] is initialized even if we break the init-loop
      'if (!recvdata.m_transporters.get(node_id))'
            
      Tescase is running the ndb_basic.test with a config specifying multiple
      receiver threads.

      This is a followup to revno: 4961: 
      'Update of SPJ component in pre 7.2 branches'.
      
      That commit back ported parts but not all of the online upgrade logic for
      SPJ to 7.0. This commit backports the remainder of the online upgarde logic,
      that is, the parts concerning the API and the TC blocks.
      
      This commit also removes testcases that will no longer work (because of version
      checks) from the daily-basic script. This change should be manually reverted
      when merging this commit to 7.2, as the tests are still supposed to work there.
      Instead, a new test that check that it is not possible to SPJ API extensions
      in pre 7.2 releases have been written (and also added to daily-basic).
      
      Finally, a check of the API version has been added in the API, such that it
      is not possible to use SPJ from API client linked with a pre 7.2 API library.
      (Before this commit, it would have been possible to run a 7.0 client against
      7.2 data nodes.)
