Auto-merge from mysql-trunk-bugfixing.

******
This patch fixes the following bugs:
  - Bug#5889: Exit handler for a warning doesn't hide the warning in
    trigger
  - Bug#9857: Stored procedures: handler for sqlwarning ignored
  - Bug#23032: Handlers declared in a SP do not handle warnings generated
    in sub-SP
  - Bug#36185: Incorrect precedence for warning and exception handlers

The problem was in the way warnings/errors during stored routine execution
were handled. Prior to this patch the logic was as follows:

  - when a warning/an error happens: if we're executing a stored routine,
    and there is a handler for that warning/error, remember the handler,
    ignore the warning/error and continue execution.

  - after a stored routine instruction is executed: check for a remembered
    handler and activate one (if any).

This logic caused several problems:

  - if one instruction generates several warnings (errors) it's impossible
    to choose the right handler -- a handler for the first generated
    condition was chosen and remembered for activation.

  - mess with handling conditions in scopes different from the current one.

  - not putting generated warnings/errors into Warning Info (Diagnostic
    Area) is against The Standard.

The patch changes the logic as follows:

  - Diagnostic Area is cleared on the beginning of each statement that
    either is able to generate warnings, or is able to work with tables.

  - at the end of a stored routine instruction, Diagnostic Area is left
    intact.

  - Diagnostic Area is checked after each stored routine instruction. If
    an instruction generates several condition, it's now possible to take a
    look at all of them and determine an appropriate handler.

mysql-test/r/signal.result:
  Update result file:
    1. handled conditions are not cleared any more;
    2. reflect changes in signal.test
mysql-test/r/signal_demo3.result:
  Update result file: handled conditions are not cleared any more.
  Due to playing with max_error_count, resulting warning lists
  have changed.

  Make a test case more readable in the result file.
mysql-test/t/sp-code.test:
  Add a test case for Bug#23032 checking that
  No Data takes precedence on Warning.
mysql-test/t/sp-error.test:
  Adding test cases for:
    - Bug#23032
    - Bug#36185
    - Bug#5889
    - Bug#9857
mysql-test/t/sp.test:
  Fixing test case to reflect behavioral changes made by the patch.
sql/sp_head.cc:
  Reset the per-statement warning count before executing
  a stored procedure instruction.
  
  Move to a separate function code which checks the
  completion status of the executed statement and searches
  for a handler.
  
  Remove redundant code now that search for a handler is
  done after execution, errors are always pushed.
sql/sp_pcontext.h:
  Remove unused code.
sql/sp_rcontext.cc:
  - Polish sp_rcontext::find_handler(): use sp_rcontext::m_hfound instead
    of an extra local variable;
  
  - Remove sp_rcontext::handle_condition();
  
  - Introduce sp_rcontext::activate_handler(), which prepares
    previously found handler for execution.
  
  - Move sp_rcontext::enter_handler() code into activate_handler(),
    because enter_handler() is used only from there;
  
  - Cleanups;
  
  - Introduce DBUG_EXECUTE_IF() for a test case in sp-code.test
sql/sp_rcontext.h:
  - Remove unused code
  - Cleanups
sql/sql_class.cc:
  Merge THD::raise_condition_no_handler() into THD::raise_condition().
  After the patch raise_condition_no_handler() was called
  in raise_condition() only.
sql/sql_class.h:
  Remove raise_condition_no_handler().
sql/sql_error.cc:
  Remove Warning_info::reserve_space() -- handled conditions are not
  cleared any more, so there is no need for RESIGNAL to re-push them.
sql/sql_error.h:
  Remove Warning_info::reserve_space().
sql/sql_signal.cc:
  Handled conditions are not cleared any more,
  so there is no need for RESIGNAL to re-push them.

/**
Find an SQL handler for any condition (warning or error) after execution
of a stored routine instruction. Basically, this function looks for an
appropriate SQL handler in RT-contexts. If an SQL handler is found, it is
remembered in the RT-context for future activation (the context can be
inactive at the moment).
If there is no pending condition, the function just returns.
If there was an error during the execution, an SQL handler for it will be
searched within the current and outer scopes.
There might be several errors in the Warning Info (that's possible by using
SIGNAL/RESIGNAL in nested scopes) -- the function is looking for an SQL
handler for the latest (current) error only.
If there was a warning during the execution, an SQL handler for it will be
searched within the current scope only.
If several warnings were thrown during the execution and there are different
SQL handlers for them, it is not determined which SQL handler will be chosen.
Only one SQL handler will be executed.
If warnings and errors were thrown during the execution, the error takes
precedence. I.e. error handler will be executed. If there is no handler
for that error, condition will remain unhandled.
Once a warning or an error has been handled it is not removed from
Warning Info.
According to The Standard (quoting PeterG):
An SQL procedure statement works like this ...
SQL/Foundation 13.5 <SQL procedure statement>
(General Rules) (greatly summarized) says:
(1) Empty diagnostics area, thus clearing the condition.
(2) Execute statement.
During execution, if Exception Condition occurs,
set Condition Area = Exception Condition and stop
statement.
During execution, if No Data occurs,
set Condition Area = No Data Condition and continue
statement.
During execution, if Warning occurs,
and Condition Area is not already full due to
an earlier No Data condition, set Condition Area
= Warning and continue statement.
(3) Finish statement.
At end of execution, if Condition Area is not
already full due to an earlier No Data or Warning,
set Condition Area = Successful Completion.
In effect, this system means there is a precedence:
Exception trumps No Data, No Data trumps Warning,
Warning trumps Successful Completion.
NB: "Procedure statements" include any DDL or DML or
control statements. So CREATE and DELETE and WHILE
and CALL and RETURN are procedure statements. But
DECLARE and END are not procedure statements.
