            localhost/default port

When creating federated table that points to unspecified host or
localhost on unspecified port or port is 0, small memory leak occurs.

This happens because we make a copy of unix socket path, which is
never freed.

With this fix we do not make a copy of unix socket path, instead
share->socket points to MYSQL_UNIX_ADDR constant directly.

This fix is covered by a test case for BUG34788.

Affects 5.0 only.

            correctly - crashes server !

Creating federated table with connect string containing empty
(zero-length) host name and port is evaluated as 0 (port is
incorrect, omitted or 0) crashes server.

This happens because federated calls strcmp() with NULL pointer.

Fixed by avoiding strcmp() call if hostname is set to NULL.

When there are no underlying tables specified for a merge table,
SHOW CREATE TABLE outputs a statement that cannot be executed. The
same is true for mysqldump (it generates dumps that cannot be
executed).

This happens because SQL parser does not accept empty UNION() clause.

This patch changes the following:
- it is now possible to execute CREATE/ALTER statement with
  empty UNION() clause.
- the same as above, but still worth noting: it is now possible to
  remove underlying tables mapping using ALTER TABLE ... UNION=().
- SHOW CREATE TABLE does not output UNION() clause if there are
  no underlying tables specified for a merge table. This makes
  mysqldump slightly smaller.

This is a test case fix for BUG#13861.

When concurrent inserts were disabled, statements after an INSERT
were not put into the query cache. This happened because we do not
save the current data file length at statement start when
concurrent inserts are disabled. But we checked the always zero
local length against the real file length anyway.
  
Fixed by doing the check only if concurrent inserts are not diabled.

  
Disable test case for bug 29948, which is causing sporadically
failures in other tests inside mysql_client_test.

The test file tried to use a mysqltest command '--warning'
but there is no such command.

Changed '--warning' to '#--warning'.

Problem: if the IO slave thread is attempting to connect,
STOP SLAVE waits for the attempt to finish. 
It may take a long time.
Fix: don't wait, stop the slave immediately.

Affected tests fixing. After the fix for st_relay_log_info::wait_for_pos() that
handles widely used select('master-bin.xxxx',pos) invoked by mysqltest
there appeared to be four tests that either tried synchronizing when
the slave was stopped or used incorrect synchronization method like
to call `sync_with_master' from the current connection being to the
master itself.

Fixed with correcting the current connection or/and using the correct
synchronization macro when possible.

No error code was returned by mysqldump if it detects that binary
logging is not enabled on the server.
Fixed by returning error code.

MASTER_POS_WAIT return values are different than expected when the server is not a slave. 
It returns -1 instead of NULL.

Fixed with correcting  st_relay_log_info::wait_for_pos() to return the proper
value in the case of rli info is not inited.
