  Bug #47304 Test main.mdl_sync fails on embedded server

  The problem was that SHOW PROCESSLIST was trying to access
  a thread that was not properly running and therefore had an 
  uninitialized mutex.

  This patch explicitly resets thd->mysys_var after each embedded
  server command to prevent the mutex from being accessed in an
  illegal state.

  The patch also re-enables lock_multi.test and mdl_sync.test for 
  embedded server as they had been disabled because of this bug.

  Bug#41971: Thread state on embedded server is always "Writing to net"
 
  The problem is that the state of a thread on a embedded server is
  always displayed as "Writing to net", which is wrong as there is
  no "network" in the embedded server.

  The solution is only exclude, on a embedded server, the thread
  state conditions that are related to network operations. Other
  thread states related to waiting on conditions or other operations
  are preserved.

SIGWINCH is not defined in termios.h on HP/UX.

  
Added this option, named as "--dump-slave". The purpose of this option is to be
able to produce a dump from a slave used for making backups of the master. Originally,
dumping from the main master was fine, but as more data accumulated, the dump process
would take over 30 minutes, locking up the master database hence website for 30 minutes.
A slave dedicated to producing backups was the answer, but I needed a dump that could be

used to restore a slave instantly and in order to do that, it has to have three things 
contained in the dump:
  
  1. "STOP SLAVE;" at the beginning
  2. "CHANGE MASTER TO ...<the master - info from 'show slave status'>"
  3. "START SLAVE;" at the end
  
These options in this changeset contain this.
  
  --stop-slave adds "STOP SLAVE" to the beginning of the dump and "STOP SLAVE" 
  to the end of the dump.
  
  --include-host gives the user the option to have the host explicitely added
  to the "CHANGE MASTER TO ..." line.
  
  --dump-slave adds the "CHANGE MASTER ..." to the dump representing not the slave's
  master binlog info, but the slave's master's info from "SHOW SLAVE STATUS" 

  
Feature from Eric Bergen, CLA signed 2007-06-27.
  
Adds new mysql client option "--auto-vertical-output", which causes
the client to test whether a result table is too wide for the current
window (where available) and emit vertical results in that case.
Otherwise, it sends normal tabular results.

           deadlocks

Backport of revno: 2617.68.35

The problem was that if one connection is running a multi-statement 
transaction which involves a single partitioned table, and another 
connection attempts to alter the table to drop a non-existing partition,
(which of course will fail), the first connection still gets 
ER_LOCK_DEADLOCK and cannot proceed anymore.

This bug is no longer reproducable. This has also been tested with the
patch for Bug#46654 "False deadlock on concurrent DML/DDL with partitions, 
inconsistent behavior" which concerned a similar problem but where the 
ALTER TABLE is semantically correct.

Test case added in partition_sync.test.

      
Another code-path dropped sign of TIME, presuming all time is positive.
      
Minds sign now. Patch depends on ChangeSet for 42661.

Bug#42662: maketime() and signedness
      
Item_time_typecast::val_int() dropped sign from
MYSQL_TIME gotten using from get_time().
      
Propagates sign now.


Backported to 5.5.0  (6.0-codebase revid: 1810.3897.1)

      
When less than six places are given for microseconds, we zerofill from
the right (leftmost place is always 1/10s). We only did this when all
announced date/time fields were given; now we also format fractional
seconds when more significant fields are left out.

  
The presence of "--skip" parameters is obscure, when it should be
obvious from the text.
  
Now, for boolean options, when they're default to ON and the --skip
is more useful parameter, then tell the user of its existence.

Backported from 6.0-codebase, revid  2572.14.1

Backport for 5.5

In non debug builds, the statements:
- SHOW PROCEDURE CODE
- SHOW FUNCTION CODE
used to fail with a "syntax error", which is misleading.

These statements have been changed to return the following error for non
debug builds:
ERROR HY000: The 'SHOW PROCEDURE|FUNCTION CODE' feature is disabled; you
need MySQL built with '--with-debug' to have it working

For debug builds (./configure --with-debug), nothing is changed.

When the query cache is disabled, the server shouldn't attempt to take the
