[svn-r16194] Purpose:

    Bug Fix

Description:

    Resolved issues with broken sanity checks that were failing when the 'b2'
    debugging package was enabled (v2 b-tree debugging):

        - Fixed outdated assertions that would not compile. They now compile
          and function correctly.

        - Removed too far outdated assertions that would require too much 
          unnecessary refactoring of code in order to satisfy their
          initial purpose.

        - Re-enabled b2 debugging package when "--enable-debug=all" is
          specified on the configure line.

Tested:

    jam, smirom, linew
