the result takes its charset/collation
attributes from the character string,
e.g.  SELECT func(NULL, _latin2'string')
now returns a latin2 result. This is
done by introducing a new derivation
(aka coercibility) level DERIVATION_IGNORABLE,
which is used with Item_null.
2. 'Pure' NULL is now BINARY(0), not CHAR(0).
I.e. NULL is now more typeless.

  Fix a bug in InnoDB code that fortunately was never used: row id is stored in a record always as a 6-byte unsigned integer, in a 'non-compressed' form

  fix to make make -jN work

  added so that it is possible to make mysql_test_run_new
  but not done for target all do:
   make mysql_test_run_new

  remove mysql_test_run_new for now, it breaks the make

  changed make order

  Bug #6479  ALTER TABLE ... changing charset fails for TEXT columns
  Fix: use do_conv_blob rather than do_copy_blob
  if the column's character sets are different.

    created new facade object for CommandInterpreter
    removed CPC #if 0 code
    removed editline from mgmtsrver, no replace with readline since interface is obsolete anyways

fix null handling in ha_ndbcluster when using ordered index

1) fix so that missing blob tables don't prevent table from being
    dropped
2) decrease size of blob part if record length exceeds max length
3) add test case for table wo/ corresponding blob table
4) init scan counters when sending scan_tabreq

  Bug#6345 Unexpected behaviour with partial indices

Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root
