      Fix for bug #29131: SHOW VARIABLES reports variable 'log' but SET · 99f4b743

      This is a 5.0 version of the patch, it will be null-merged to 5.1
      
      Problem:
      
      'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up
      in SHOW VARIABLES, but could not be used in expressions like 
      "select @@log". Also, using them in the SET statement produced an 
      incorrect "unknown system variable" error.
      
      Solution:
      
      Make 'log' and 'log_slow_queries' read-only dynamic variables to make 
      them available for use in expressions, and produce a correct error 
      about the variable being read-only when used in the SET statement.

      Fixed bug #27695: View should not be allowed to have empty or · e36846de

      all space column names.
      
      The parser has been modified to check VIEW column names
      with the check_column_name function and to report an error
      on empty and all space column names (same as for TABLE
      column names).

      Bug #30715: Assertion failed: item_field->field->real_maybe_null(), · 54cea400
      gkodinov/kgeorge@magare.gmz authored
        file .\opt_sum.cc, line
      The optimizer pre-calculates the MIN/MAX values for queries like
       SELECT MIN(kp_k) WHERE kp_1 = const AND ... AND kp_k-1 = const
      when there is a key over kp_1...kp_k
      In doing so it was not checking correctly nullability and 
      there was a superfluous assert(). 
      Fixed by making sure that the field can be null before checking and
      taking out the wrong assert().
      .
      Introduced a correct check for nullability 
      The MIN(field) can return NULL when all the row values in the group
      are NULL-able or if there were no rows.
      Fixed the assertion to reflect the case when there are no rows.
