autotools runs
- Fix recognition of --with-debug=full in configure wrapper
- Remove CMakeCache.txt in configure wrapper, to match the original
- Fix recognition of max-no-ndb
- Fix broken dependencies of mysql_fix_privilege_table.sql from 
  mysql_system_tables.sql and mysql_system_tables_fix.sql
- Add "distclean target" that informs user about appropriate bzr command



cmake/configure.pl:
  - Recognize --with-debug=full, map to WITH_DEBUG_FULL
  - remove CMakeCache.txt, so the configuration is no more sticky
  (to match the original configure behavior)
cmake/plugin.cmake:
  - Recognize WITH_MAX_NO_NDB, this fixes missing storage engines after BUILD/*max-no-ndb scripts
mysql-test/CMakeLists.txt:
  test-force uses the same macros (MTR_FORCE) as test-bt* now
scripts/CMakeLists.txt:
  - Fix broken dependency when producing mysql_fix_privilege_tables.sql, reported by Davi.
  We now concatenate 2 scripts in custom command that
  has dependency on both scripts rather than concatenating them at cmake time.
sql/CMakeLists.txt:
  Address frequently asked question "where is distclean" by implementing distclean target 
  that does nothing except pointing to appropriate 
  bzr command.
  
  It is better not to call "bzr clean-tree" automatically, without user consent.
  It could clean new files that were meant to be added.
