databases from 4.0 server

mysqldump treated a failure to set the results charset as a severe
error.  

Now, don't try to set the charset for the SHOW CREATE TABLE statement,
if remote server's version is earlier than 4.1, which means it 
doesn't support changing charsets.

Nothing was in the command-line dictionary, because of the wrong 
order of instructions when populating it.

This is a smaller, less optimistic patch that both fixes a bug and
refreshes the list of keywords that the command-line library (e.g., 
readline) can use to expand typed commands.  Now, read from the 
command list /after/ we free the list, not before.

The best way is to read the keywords from the lexer code, but that
doesn't work everywhere yet.  Grr.

Bug#33976: buffer overflow of variable time_buff in function com_go()

An internal buffer was too short.  Overextending could smash the 
stack on some architectures and cause SEGVs.  This is not a problem
that could be exploited to run arbitrary code.

To fix, I expanded one buffer to cover all the size that could be
written to (we know the abolute max).

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.

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.

The problem occurred when one had a subquery that had an equality X=Y where 
Y referred to a named select list expression from the parent select. MySQL 
crashed when trying to use the X=Y equality for ref-based access. 

Fixed by allowing non-Item_field items in the described case.

The ROUND(X, D) function would change the Item::decimals field during
execution to achieve the effect of a dynamic number of decimal digits.
This caused a series of bugs:
Bug #30617:Round() function not working under some circumstances in InnoDB
Bug #33402:ROUND with decimal and non-constant cannot round to 0 decimal places
Bug #30889:filesort and order by with float/numeric crashes server
Fixed by never changing the number of shown digits for DECIMAL when
used with a nonconstant number of decimal digits.
