crashes mysqld": implementation for a generic item tree modifications
registry. Every item tree modification which should be rolled back for
subsequent execution of a prepared statement or stored procedure should
be saved in the registry. All such modifications are rolled back at once
during cleanup stage of PS.
Actual fix for the bug just adds a call to register modifications to
convert_constant_item.
Post review fixes implemented.

  A fix for bug#5748, test results fixed.

sql/item.cc:
  Fix for Bug#5748 "Prepared statement with BETWEEN and bigint values
  crashes mysqld":
  First step in removing up item-specific cleanups: now all such
  tree modifications should be done using the genericm mechanism implemented
  in this changeset.
sql/item.h:
  Fix for Bug#5748 "Prepared statement with BETWEEN and bigint values
  crashes mysqld": no need for an item-specific change record any more.
sql/item_cmpfunc.cc:
  A fix for Bug#5748 "Prepared statement with BETWEEN and bigint

  conventional execution.
sql/sql_prepare.cc:
  Use of the item tree modifications registry in prepared statements:
  rollback all modifications in the end of statement prepare and execute.
  Also we now always set thd->current_arena to be able to determine that
  this is an execution of prepared statement inside the registry code.
tests/client_test.c:
  A typo fixed.

introduced during implementation of TIMESTAMP columns, which are able 
to store NULLs (Unfortunately it is impossible to write test case for
this. Kudos to Holyfoot for noticing it!)


sql/field.cc:
  Field_timestamp::get_auto_set_type(): To preserve compatibility 
  with pre-4.1 we have to handle TIMESTAMP_OLD_FIELD columns properly. 
  (It is ok to handle them as TIMESTAMP_DNUN_FIELD since value of first
   such column should be set to current timestamp on both INSERT and UPDATE
   operations, and we don't call this method for rest of them).

with the system-reserved (and system-defined) '_REENTRANT' 
CPP identifier.
Especially, it must not be "undefine"d, because the Tru64 compiler
needs it if threads are enabled.


include/my_pthread.h:
  On Tru64, '_REENTRANT' is set by the compiler when the "-pthread" 
  option is given, and it must be set when the system's 'pthread.h' is 
  included (or else a '#error' is activated).
  So it must not be undef'ed, and it should not be def'ed either, as it
  is a system-reserved CPP identifier with which we should not mess
  anyway - it is risky to use it!
  Build on all platforms was checked privately, change caused no errors!
