empty result when using DESC

Problem: fetching MyISAM keys we copy a key block pointer to the end of the key buffer.
However, we don't take into account the pointer length calculatig the buffer size,
that may leads to memory overwriting and in turn to unpredictable results.

Fix: increase key buffer size by length of the key block pointer.

Note: no simple test case.

  Fix for bug #33758: Got query result when using ORDER BY ASC, but 
  empty result when using DESC
    - increase possible maximum key length by size of the key block pointer,
      as it's copied into the key buffer in the get_key() MyISAM functions.

Here is the scenario that causes the failure.(by Mats)

1. The to-be corrupt log event (let's call it X), is split into two
   packets B and C on the network level (net_write_buff()). The parts
   are X = (x',x''). The part x' ends up in packet B and part x''
   ends up in packet C. Prior to the corrupt event X, the event Y has
   been written successfully, but has been split into two packets as
   well, which we call (y',y'').
2. The master sends packet A = (y'',x') to the slave, increases the
   packet sequence number, the slave receives the packet, but fails
   to reply before the master gets a timeout.
3. Since the master got a timeout, it reports failure, and aborts
   sending the binary log by exiting mysql_binlog_send(). However, it
   leaves the buffer intact, still holding y'' (but not x', since the
   write_pos is not increased).
4. After exiting mysql_binlog_send(), the master does a
   disconnection of the client thread, which involves sending an
   error message e to the client (i.e., the slave).
5. In this case, net_write_buff() is used again, but this time the
   old contents of the packet is used so that the new packet is
   D = (y'',e). Note that this will use a new packet sequence number,
   since the packet number was increased in step 2.
6. The slave receives the tail y'' of the Y log event, concatenates
   this with x' (which it already received), and writes the event
   (x',y'') it to the relay log since it hasn't noticed anything is
   amiss.
7. It then tries to read more bytes, which is either e (if the length
   given for X just happened to match the length given for Y, or just
   plain garbage because the slave is out of sync with what is
   actually sent.
8. After a while, the SQL thread tries to execute the event (x',y''),
   which is very likely to be just nonsense.

The problem can be fixed by not resetting net->error after the call of 
mysql_binlog_send, so the error message will not be sent and the connection
will be closed.


sql/sql_parse.cc:
  Do not reset net->error, if net->error == 2, we should not try to use the connection again

and so that it works correctly on Windows.

The problem is when create/rename/drop users, the statement was logged regardless of error, even if no data has been changed, the statement was logged.

After this patch, create/rename/drop users don't write the binlog if the statement makes no changes, if the statement does make any changes, log the statement with possible error code.

This patch is based on the patch for BUG#29749, which is not pushed

Bug 33983 (Stored Procedures: wrong end <label> syntax is accepted)

The server used to crash when REPEAT or another control instruction
was used in conjunction with labels and a LEAVE instruction.

The crash was caused by a missing "pop" of handlers or cursors in the
code representing the stored program. When executing the code in a loop,
this missing "pop" would result in a stack overflow, corrupting memory.

Code generation has been fixed to produce the missing h_pop/c_pop
instructions.

Also, the logic checking that labels at the beginning and the end of a
statement are matched was incorrect, causing Bug 33983.
End labels, when used, must match the label used at the beginning of a block.

Bug#25347: mysqlcheck -A -r doesn't repair table marked as crashed

mysqlcheck tests nullness of the engine type to know whether the
"table" is a view or not.  That also falsely catches tables that 
are severly damaged.

Instead, use SHOW FULL TABLES to test whether a "table" is a view
or not.

(Don't add new function.  Instead, get original data a smarter way.)

Make it safe for use against databases before when views appeared.


client/mysqlcheck.c:
  Use SHOW FULL TABLES to test better whether a name in the table
  list is one of a view.  Checking that the engine is NULL is 
  insufficient.
  
  Implemented suggestion from jimw that involved removing most of 
  original patch and getting data a better way
mysql-test/r/mysqlcheck.result:
  Verify that tables that have NULL/unreadable engine types are 
  processed and not interpreted as views.
mysql-test/t/mysqlcheck.test:
  Verify that tables that have NULL/unreadable engine types are 
  processed and not interpreted as views.

Patch by Kasper Dupont.  No CLA required for this size of patch.

"resolveip" program produces incorrect result if given a hostname
starting with a digit.  Someone seems to have thought that names 
can not have digits at the beginning.

Instead, use the resolver library to work out the rules of hostnames, 
as it will undoubtedly be better at it than we are.


configure.in:
  See if we need to a library for address lookups.
extra/resolveip.c:
  Don't use silly heuristic to know whether a string is a dotted
  quad.  Instead, pass the whole thing into the resolver and let
  its smarts do all the work.
