Fix for a valgrind warning due to a jump on a uninitialized
variable. The problem was that the sql profile preparation
function wasn't being called for all possible code paths
of query execution.

The solution is to ensure that query profiling is always
started before dispatch_command function is called and to
explicitly call the profile preparation function on bootstrap.

The problem:
CSV storage engine open function returns success even
thought it failed to open the data file
The fix:
return error
Additional fixes:
added MY_WME to my_open to avoid mysterious error message
free share struct if open the file was unsuccessful

Problem: missed "break" in a switch leads to unexpected assertion failure
of 'myisamchk compressed_table'.

Fix: add the break.

Problem: REGEXP in functions/PSs may return wrong results
due to improper initialization.

Fix: initialize required REGEXP params.

The problem was because the event allocated in mysql_client_binlog_statement
was not freed when an error occured while applying the event.

    Test "funcs_1.processlist_val_ps" fails in various ways
+ corrections of logic in poll routines
+ minor improvements

Details:
- add subtest with drop unrelated view
- rearrange existing tests so that a distinction
  between drop procedure and drop function effects
  is possible

Post push fix

an DBUG_ASSERT broke the embedded server, fixed by initializing
it in the embedded version of Protocol_text::prepare_for_resend

Post push fix (compiler warning)

This fix is for 5.1 only : back porting the 6.0 patch manually

The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.

Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes

With this fix:
- C++ constructors are *not* executed with a NULL "this" pointer
when operator new fails.
This is achieved by declaring "operator new" with a "throw ()" clause,
so that a failed new gracefully returns NULL on OOM conditions.

- calls to new/alloc are tested for a NULL result,

- The thread diagnostic area is set to an error status when OOM occurs.
This ensures that a request failing in the server properly returns an
ER_OUT_OF_RESOURCES error to the client.

- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
This prevents causing further crashes when using a partially built parsed
tree in further rules in the parser.

No test scripts are provided, since automating OOM failures is not
instrumented in the server.
Tested under the debugger, to verify that an error in alloc_root cause the
thread to returns gracefully all the way to the client application, with
an ER_OUT_OF_RESOURCES error.

BUG#38369, enable rpl_row_basic_7ndb test

partition is corrupt

Updated result files after merge

Post-merge fix: mysql_client_test.c is compiled by C compilers
and some C compilers don't support mixed declarations and code
and it's explicitly forbidden by ISO C90.

Note: NULL merge of sql/sql_yacc.yy, the fix for bug#38296 will be provided separately for 5.1

Fixed missing DBUG_RETURN in the function find_key_block
