This allows us to use statement replication with functions and triggers
The following things are fixed with this patch:
- NOW() and automatic timestamps takes the value from the main event for functions and triggers (which allows these to replicate with statement level logging)
- No side effects for triggers or functions with auto-increment values(), last_insert_id(), rand() or found_rows()
- Triggers can't return result sets

Fixes bugs:
#12480: NOW() is not constant in a trigger
#12481: Using NOW() in a stored function breaks statement based replication
#12482: Triggers has side effects with auto_increment values
#11587: trigger causes lost connection error


mysql-test/r/trigger.result:
  Added test fpr big
mysql-test/t/sp-error.test:
  Changed error message numbers
mysql-test/t/trigger.test:

sql/item_func.cc:
  Store the first used seed value for RAND() value.
  (This makes rand() replicatable in functions and triggers)
  Save and clear run context before executing a stored function and restore it afterwards.
  This removes side effects of stored functions for RAND(), auto-increment values and NOW() and makes most stored function replicatable
sql/share/errmsg.txt:
  Reuse error message also for triggers
sql/sp_head.cc:
  If in function or trigger, don't change value of NOW()
  (This allows us to use statement replication with functions that directly or indirectly uses timestamps)
sql/sql_class.cc:
  Added framework for storing and retrieving run context while exceuting triggers or stored functions.

sql/sql_parse.cc:

sql/sql_trigger.h:
  Moved process_triggers function from sql_trigger.h

sql/sql_yacc.yy:
  Give error message if trigger can return a result set (Bug #11587)

  Removed return from end of lines

  Fixed bug #12382.
  INSERT statement effectively changed thd->set_query_id to 0,
  while SELECT statement changed it to 0. As a result
  the insert_fields function that expanded '*' was called
  with different values of thd->set_query_id for the query
  SELECT * FROM view depending on whether it was run after
  an INSERT or after a SELECT statement. This was corrected
  by restoring the old value of thd->set_query_id when
  returning from the function setup_fields where possible
  reset could occur.
  If the value of thd->set_query_id == 0 then the fields
  substituted instead of '*' were not registered as used
  for bitmaps used_keys. This caused selection of an invalid
  execution plan for the query SELECT * from <view>.

cursors (+ commit)" and Bug#11832 "Server crash with InnoDB + Cursors"
See comments to the changed files.


innobase/include/read0read.h:
  - add cursor_view_t::n_mysql_tables_in_use
innobase/read/read0read.c:
  - maintain cursor_view_t::n_mysql_tables_in_use. InnoDB
  maintains trx->n_mysql_tables_in_use to know when it can auto-commit
  a read-only statement. When this count drops to zero,
  MySQL has ended processing of such statement and InnoDB can commit.
  Cursors should not break this invariant, and should exclude the tables
  used in a cursor from the count of active tables.
  When a cursor is closed, the number of its tables is added back, 
  to ensure that close_thread_tables->unlock_external->
  ha_innobase::external_lock(F_UNLCK) won't drop the count in trx 
  below zero.
innobase/row/row0sel.c:
  - remove the restoration of the global read view from 
  row_search_for_mysql: MySQL may call row_search_for_mysql
  more than once when fetching a row for a cursor (e.g. if there
  is a WHERE clause that filters out some rows).
sql/ha_innodb.cc:
  - add more verbose printout for the case when we close an InnoDB
  connection without priorlly issuing a commit or rollback. The problem
  should be investigated.
