crashes server." The fix makes Item_func_rand prepared-statements
aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.


mysql-test/r/ps.result:
  A test case for Bug#5985: test results fixed.
mysql-test/t/ps.test:
  A test case for Bug#5985 "prepare stmt from "select rand(?)" crashes

  prepared statements aware.
sql/item_func.h:
  Actual fix for Bug#5985: Item_func_rand rewritten to be 
  prepared statements aware.
sql/mysql_priv.h:
  We need a separate call to reset THD state before every execute of
  a prepared statement. Otherwise things like THD->user_var_events
  are never cleaned up and bloat binary log (as the list of events
  grows from execution to execution).
sql/sql_class.cc:
  Statement::end_statement -> THD::end_statement()
  (a leftover from some design change which is not to pushed now, but the
  leftover is to be pushed).
sql/sql_class.h:
  Statement::end_statement -> THD::end_statement()
  (a leftover from some design change which is not to pushed now, but the
  leftover is to be pushed).
sql/sql_lex.cc:
  Move the part responsible for initializing LEX from mysql_init_query
  to lex_start.
sql/sql_lex.h:
  All lex-related initialization is now in lex_start.
  Move thd->select_number to lex->select_number to be able to use it
  easily in lex_start.
sql/sql_parse.cc:
  Split mysql_init_query into two functions: mysql_reset_thd_for_next_query,
  which is used in PS and conventional execution, and lex_start, used only
  when we want to parse something.
  Fix init_connect to use initialized THD.
sql/sql_prepare.cc:
  Deploy mysql_reset_thd_for_next_query to reset THD state before
  execution of a prepared statement.
  Normally this should have been added to just one place, but
  we have to reset thd before assigning placeholders from variables,
  thus we can't do that in execute_stmt (yuck).

Added a check to recover from IGNORE_SPACE in this situation: 
<ident-character(s)><space><dot><ident-character(s)>
The ignored space led to the false identification of the dot
as an ident separator (like "db.table").


mysql-test/r/sql_mode.result:
  BUG#5318 - failure: 'IGNORE_SPACE' affects numeric values after DEFAULT.
  Added the test results.

execute crashes server": we were deleting lex->result
after each execute, but prepared statements assumed that
it's left intact.
The fix adds cleanup() method to select_result hierarchy,
so that result objects can be reused.
Plus we now need to delete result objects more wisely.


mysql-test/r/ps.result:
  Test results fixed: test case for bug#5034
mysql-test/t/ps.test:
  A test case for bug#5034, few followups
sql/sql_class.cc:
  - fix warning in THD::THD
  - implementation of cleanup() for select_result hierarchy
  - select_export::send_eof was identical to 
    select_dump::send_eof: moved to the base class select_to_file.
  - Statement::end_statement() to end lex, free items, and
    delete possible select_result
sql/sql_class.h:
  - select_result::cleanup() declaration
  -
sql/sql_insert.cc:
  - implementation of select_insert::cleanup(): currently
    we always create a new instance of select_insert/
    select_create on each execute.
sql/sql_lex.cc:
  - with more complicated logic of freeing lex->result it's 
    easier to have it non-zero only if it points to a valid
    result.
sql/sql_lex.h:
  Now st_lex::st_lex is not empty.
sql/sql_parse.cc:
  mysql_execute_command():
  - delete select_result *result only if it was created in
    this function.
  - use end_statement() to cleanup lex and thd in the end of
    each statement.
  - no need to save THD::lock if this is explain. This save
    apparently left from times when derived tables were 
    materialized here, not in open_and_lock_tables.
sql/sql_prepare.cc:
  - call result->cleanup() in reset_stmt_for_execute
  - now Statement is responsible for freeing its lex->result.
sql/sql_select.cc:
  handle_select():
  - don't delete result, it might be needed
    for next executions
  - result is never null

 a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement 
execute a subtree with negation was replaced with equivalent 
subtree without NOTs.
The problem was that although this transformation was permanent, 
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(), 
  Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
  THD::free_temporary_pool_for_ps_preparing(); they
  were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
  prepared statement, it points at the thd. 
The rest of the patch con...

Instead of trying to open time zone tables during calculation of CONVERT_TZ() function
or setting of @@time_zone variable we should open and lock them with the rest of

pre-opened tables for loading info about time zones.

The code in mysql_create_table() code assumes that if lower_case_names==2 then table alias 
should contain unchanged table name, and this was not true for temporary tables which
had 'tmp-table' constant as alias. Now we are using table name as alias for such tables.


sql/sql_lex.cc:
  Removed tmp_table_alias constant which is no longer used.
sql/sql_lex.h:
  Removed tmp_table_alias constant which is no longer used.
sql/sql_yacc.yy:
  Let us use table name instead of 'tmp-table' as alias for table being created by 
  CREATE TEMPORARY TABLE statement. This fixes failing temp_table.test on Darwin 7.3 
  since mysql_create_table() code assumes that if lower_case_names==2 then table alias 
  should contain unchanged table name (and now this assumtion is true but it were false
  for temporary tables before...).
