libmysql/manager.c:
  Code clean-up: as my_net_read() returns ulong value we should use ulong here.

Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now for determining
if we should auto-set value of TIMESTAMP field during this operation.
We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().

 Fix for Bug#6025 "Test "client_test" fails in 4.1.6-gamma build (2)".
 No need for a test case, the bug is covered already.


libmysql/libmysql.c:
  Fix for Bug#6025 "Test "client_test" fails in 4.1.6-gamma build (2)":
  the bug was in assignments like:
    *row+= read_binary_time(tm, row);
  which makes two assingments without a sequence point (read_binary_*
  changes *row too) => undefined behaviour.
  The fix changes read_binary_{time,date,datetime} signature to get
  rid of any probability to fall into the same trouble in future.

  If innodb_locks_unsafe_for_binlog options is used we do not lock
  gaps. Supremum record is really a dummy record i.e. gap, therefore

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.

sql/item_func.h:
  Actual fix for Bug#5985: Item_func_rand rewritten to be

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).

  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).
