forgott to add KeyDescriptor.hpp

  LQH computes incorrect hash values during NR (as it doesn't concider charsets)

  Solution: make LQH compute correct hash :-)
           1) move xfrm_key into SimulatedBlock so that there's _one_ impl.
           2) make TC, ACC, LQH use same impl.

On 64 bit platforms the changed statement doesn't work
so making sure that the larger value is first and using
subtraction is a quick and backwards-compatible fix of this
line.

NOT FOUND ...' in conditional handled incorrectly".

Whenever we remove an instruction during optimization, we need to
adjust instruction numbers (ip - instruction pointer) stored in all
instructions. In addition to that, sp_instr_hpush_jump, which 
corresponds to DECLARE CONTINUE HANDLER needs adjustment for m_handler,
which holds the number of instruction with the continue handler.
In the bug report, a wrong ip stored in m_handler was pointing at 
FETCH, which resulted in an error message and abnormal SP termination.
The fix is to just remove m_handler member from sp_instr_hpush_jump,
as it's always points to the instruction next to the DECLARE
statement itself (m_ip+1).

  Temporarily remove error print if MySQL tries to do a SELECT even though trx->n_mysql_tables_in_use is 0. We must return the error print when the lock count of cursors is properly implemented (Bug #12456)
