Problem: in case of failed 'show binlog events...' we don't inform that 
the log is not in use anymore. That may confuse following 'purge logs...'
command as it takes into account logs in use.

Fix: always notify that the log is not in use anymore.

When a UNION statement forced conversion of an UTF8
charset value to a binary charset value, the byte
length of the result values was truncated to the
CHAR_LENGTH of the original UTF8 value.


sql/item.cc:
  Fixed bug #29205.
  The calculation of data length was modified in
  the Item_type_holder::join_types method to take into
  account possible conversion of a multibyte charset
  value to a binary charset value, when each
  multibyte character is converted into a sequence
  of bytes (not to a single byte of binary charset).

spaces.

When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.

Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.

query / no aggregate of subquery
 The optimizer counts the aggregate functions that 
 appear as top level expressions (in all_fields) in 
 the current subquery. Later it makes a list of these
 that it uses to actually execute the aggregates in
 end_send_group().
 That count is used in several places as a flag whether
 there are aggregates functions.
 While collecting the above info it must not consider
 aggregates that are not aggregated in the current 
 context. It must treat them as normal expressions 
 instead. Not doing that leads to incorrect data about
 the query, e.g. running a query that actually has no
 aggregate functions as if it has some (and hence is
 expected to return only one row).
 Fixed by ignoring the aggregates that are not aggregated
 in the current context. 
 One other smaller omission discovered and fixed in the 
 process : the place of aggregation was not calculated for
 user defined functions. Fixed by calling 
 Item_sum::init_sum_func_check() and 
 Item_sum::check_sum_func() as it's done for the rest of 
 the aggregate functions.

SHOW CREATE TABLE or SELECT FROM I_S.

Actually, the bug discovers two problems:
  - the original query is not preserved properly. This is the problem
    of BUG#16291;
  - the resultset of SHOW CREATE TABLE statement is binary.

This patch fixes the second problem for the 5.0.

Both problems will be fixed in 5.1.

mysql-test/t/show_check.test:

sql/item.h:
  Use utf8_general_ci instead of binary collation by default,
  because for views and base tables utf8 is the character set
  in which their definition is stored. For system constants
  it's the default character set, and for other objects
  (routines, triggers), no character set is stored, and
  therefore no character set is known, so returning utf8
  is just as good as any non-binary character set.
  This latter problem is fixed in 5.1 by 16291. In 5.1
  we will return the "real" character set.

  Thanks to Martin Friebe for finding and submitting a fix for this bug!
  
  A table with maximum number of key segments and maximum length key name
  would have a corrupted .frm file, due to an incorrect calculation of the
  complete key length.  Now the key length is computed correctly (I hope) :-)
  
  MyISAM would reject a table with the maximum number of keys and the maximum
  number of key segments in all keys.  It would allow one less than this total
  maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
  very minor issue.)
